SUPPLEMENTARY INFORMATION: 

I. Introduction

    The NRC is considering issuance of a renewed Facility Operating 
License No. R-87, held by Purdue University, which would authorize 
continued operation of PUR-1, located in West Lafayette, Tippecanoe 
County, Indiana, for an additional 20 years. In connection with the 
renewed license, the applicant is also seeking a power increase from 1 
kW(t) to 12 kW(t). As required by section 51.21 of title 10 of the Code 
of Federal Regulations (10 CFR), ``Criteria for and identification of 
licensing and regulatory actions requiring environmental assessments,'' 
the NRC performed an EA. Based on the results of the EA that follows, 
the NRC has determined not to prepare an environmental impact statement 
for the proposed action and is issuing a FONSI.

II. Environmental Assessment

Description of the Proposed Action

    The proposed action would renew Facility Operating License No. R-87 
for a period of 20 years from the date of issuance of the renewed 
license. The proposed action would also authorize a power increase from 
1 kW(t) to 12 kW(t). The proposed action is in accordance with Purdue 
University's application dated July 7, 2008, as supplemented by letters 
dated June 30, 2008; June 3, and June 4, 2010; November 15, 2011; 
January 4, January 30, January 31, June 1, June 15, June 29, July 13, 
and August 11, 2012; April 10, 2013; July 24, 2015; and January 29, 
February 26, March 31, May 9, July 7, July 19, September 19, and 
September 29, 2016 (collectively referred to as ``the renewal 
application''). In accordance with Sec.  2.109, ``Effect of timely 
renewal application,'' the existing license remains in effect until the 
NRC takes final action on the renewal application.

Need for the Proposed Action

    The proposed action is needed to allow the continued operation of 
the PUR-1, which is used for teaching and research to support the 
mission of Purdue University, for a period of 20 years. Operation of 
the PUR-1 at the requested higher power level would expand the 
educational and research uses of the facility.

Environmental Impacts of the Proposed Action

    Separate from the environmental assessment referenced in this 
document, the NRC is writing a safety evaluation (SE) of the proposed 
action to issue renewed Facility Operating License No. R-87 to allow 
continued operation of the PUR-1 for a period of 20 years. The details 
of the NRC's SE will be provided with the renewed license, if approved. 
This document contains the EA of the proposed action.
    The applicant has requested a power increase from 1 kW(t) to 12 
kW(t) maximum allowed licensed power. The applicant performed analyses 
at 18 kW(t) to bound the requested power increase. The applicant's 
required annual reports from 2011 through 2015 indicate that no 
measurable amount of radioactive effluent was released from the PUR-1 
to the environment.

Facility Site and Environs

    The PUR-1 is a heterogeneous, pool-type non-power reactor that has 
been in operation since 1962 for teaching and research purposes. The 
PUR-1 is located in the Duncan Annex of the Electrical Engineering 
Building on the eastern edge of the Purdue University campus. The 
building was originally designed as a high voltage laboratory, and the 
space was later converted into classrooms, laboratories, and offices. 
The building is constructed of brick, concrete block, and reinforced 
concrete. Within the Duncan Annex, the PUR-1 is located within a 6,400-
gallon cylindrical water tank that is 17 feet deep and 8 feet in 
diameter. The tank is enclosed by a concrete shielding structure.
    The PUR-1 operates about 90 times per year on average. The reactor 
is fueled with standard low-enriched uranium plate-type fuel and is 
cooled by natural convection of light water. The reactor coolant system 
includes a process system, which controls the pool water temperature, 
and a purification system, which is designed to maintain pool water 
quality by limiting corrosion and coolant activation by the use of 
microfilters and ion exchange resins. Water from the pool is drawn out 
from the scupper drain or suction line via polyvinyl chloride piping 
leading to the circulating pump; a second source of water for the pump 
is a water supply tank supplied with city service water and controlled 
by a float valve. Ball valves for water shutoff and a vacuum cleaning 
connection are provided in the pump supply line. From the pump, a pipe 
with a ball valve installed leads first to the filter and then to a 
demineralizer. An adjustable by-pass or throttling valve is inserted in 
the system to regulate water flow through the demineralizer. A flow 
indicator and a conductivity indicator are installed as a check on flow 
rate and water purity

[[Page 74824]]

from the demineralizer. The water next flows through a stainless steel 
heat exchanger. The water from the heat exchanger is then returned to 
the reactor pool. A magnetrol water-level control is located in the 
reactor pool; this unit controls a solenoid valve in the line from the 
water supply tank to ensure that the prescribed pool water level is 
maintained. However, this system is manually controlled by the PUR-1 
staff to allow markup water to be inventoried. Makeup pool water is 
provided by the city public water supply.
    A detailed description of the reactor can be found in the PUR-1 
Safety Analysis Report (SAR) submitted by the applicant with its 
renewal application.
A. Radiological Impacts
Environmental Effects of Reactor Operations
    During normal operations at the PUR-1 facility, the two primary 
airborne sources of radiation are argon-41 (Ar-41) and nitrogen-16 (N-
16). N-16 is produced when oxygen in the pool water is irradiated in 
the reactor core, and must then diffuse to the pool surface before it 
is released to the atmosphere. The applicant estimates that, due to its 
short half-life (about 7 seconds), any N-16 produced by the reactor at 
the bounding power level of 18 kW(t) would decay before reaching the 
surface of the pool. The primary source of Ar-41 at the PUR-1 is from 
irradiation of air containing argon dissolved in the reactor pool. At 
the current 1 kW(t) steady-state operation, effluent samples in the 
reactor room have not contained detectable traces of Ar-41. At the 
bounding power level of 18 kW(t), the applicant estimates that steady-
state operation of the reactor would produce an equilibrium 
concentration of 2.08 x 10-7 [mu]Ci/cm\3\ of Ar-41 in the 
exhaust air and the reactor room, which is lower than the 3.0 x 
10-6 [mu]Ci/cm\3\ Derived Air Concentration (DAC) limit for 
occupational workers found in 10 CFR part 20. Due to the DAC being 
below regulatory limits, the estimated occupational radioactivity 
exposure levels will also be below the 10 CFR part 20 limit of 5 
reontgen equivalent man (rem). The estimated dose rate to a worker at 
the bounding power level of 18 kW(t) was calculated by the applicant to 
be 0.167 milli roentgen equivalent man per hour (mrem/hr) (0.00167 
millisievert/hour (mSv/hr)). Using the calculated dose rate, the total 
effective dose equivalent to a worker in the reactor room for an entire 
year would be less than 334 mrem (3.34 mSv), assuming a hypothetical 
2,000-hour steady state, full power operation, since the reactor 
license contains no restriction on operating hours. The reactor 
normally operates for much less than the assumed 8 hours per day and 
the conservatively calculated dose is still well below the 5,000-mrem 
(50 mSv) limit established in Sec.  20.1201, ``Occupational dose limits 
for adults.'' The applicant also calculated, at the bounding 18 kW(t) 
power level, an environmental public dose rate from normal operations 
to a person in the unrestricted area due to Ar-41 released from the 
building ventilation opening. The release point is on the roof vent on 
the top of the building 15 meters above ground. Assuming a hypothetical 
continuous steady state, full power operation for a year, the applicant 
calculated the public dose rate to be 3.17 x 10-4 mrem/hr 
(3.17 x 0-6 mSv/hr) or 2.8 mrem/yr (0.28 mSv/yr), which is 
well below the limit in Sec.  20.1301 of 100 mrem/yr (1 mSv/yr). This 
calculated public dose rate would also meet the as low as is reasonably 
achievable (ALARA) dose constraint of 10 mrem/yr (0.1 mSv/yr) found in 
Sec.  20.1101(d).
    Purdue University has a structured radiation safety program. 
Policies for the program are determined by the University Radiation 
Safety Committee, which has the mission to ensure the safety of the 
University and community in the utilization of all radioactive 
materials and radiation-producing devices at the University by faculty, 
staff, or students. The program is administered by the Radiation Safety 
Officer and his staff, as part of Radiological and Environmental 
Management. The staff is equipped with radiation detection 
instrumentation to determine, control, and document occupational 
radiation exposures at the reactor facility under the broad scope 
byproduct materials license held by Purdue University.
    Only very limited contaminated materials are generated by PUR-1. 
Any contaminated material is disposed of under the Purdue University 
broad scope license. No wastes have been released to the environment in 
an uncontrolled manner. During the past 5-year period from 2011 through 
2015, the applicant reported no routine releases of liquid radioactive 
waste by any disposal method. The NRC assumes that any changes due to 
the requested power increase from 1 kW(t) to 12 kW(t) are expected to 
be minimal and capable of being handled by the existing systems and 
procedures.
    As described in Chapter 11 of the PUR-1 SAR, personnel exposures 
are well within the limits set by Sec.  20.1201, ``Occupational dose 
limits for adults,'' and the ALARA dose criteria in Sec.  20.1101(b). 
The University is committed to the principle of ALARA and it makes 
every effort to keep doses to a minimum. All unanticipated or unusual 
exposures are investigated. According to annual reports for the past 5 
years of operation from 2011 through 2015, there were no radiation 
exposures greater than 25 percent of limits set forth in Sec.  20.1201. 
The change in occupational dose from the proposed power uprate from 1 
kW(t) to 12 kW(t) is discussed previously in this notice.
    The applicant monitors dose to the public by placing 
thermoluminescent dosimeters (TLD) at the boundaries of the facility. 
The TLDs are checked for exposure every other month. Doses measured 
from the TLDs at the current operating power level of 1 kW(t) have been 
at background levels, therefore, the applicant concludes that the 
public has not received exposures greater than the limits set forth in 
Sec.  20.1301, ``Dose limits for individual members of the public.'' As 
stated previously, this should not change for the proposed power 
increase of 12 kW(t). Additionally, the potential radiation dose from 
current operations at 1kW(t) also demonstrates compliance with the 
ALARA dose constraints specified in Sec.  20.1101(d), ``Radiation 
protection programs.'' As stated previously, this should not change for 
the proposed power increase of 12 kW(t).
    Over the past 5 years of operation from 2011 through 2015, results 
from the applicant's survey program indicate that radiation exposures 
at the current operating power level of 1 kW(t) at the monitoring 
locations were not significantly higher than those measured at the 
control locations. This should not change for the proposed power 
increase of 12 kW(t). Therefore, the NRC concludes that the proposed 
action would not have a significant radiological impact.
Environmental Effects of Accidents
    The maximum hypothetical accident (MHA) is an event involving the 
cladding failure of an irradiated fuel element in air. The MHA is 
considered the worst-case fuel failure scenario for PUR-1 that would 
lead to the maximum potential radiation hazard to facility personnel 
and to members of the public. The results of the MHA are used by the 
NRC to evaluate the ability of the applicant to respond and mitigate 
the consequences of this postulated radioactive release.
    The applicant conservatively calculated doses to facility personnel

[[Page 74825]]

during evacuation and the maximum potential doses to members of the 
public at various locations around the PUR-1 facility. The license 
estimated an occupational dose of 317 mrem (3.17 mSv), for a one minute 
(evacuation) duration, and 47 mrem (0.47 mSv) for the maximum exposed 
member of the public. The NRC performed independent calculations to 
verify that the applicant's calculated doses represented conservative 
estimates for the MHA. The NRC, using conservative assumptions, 
estimated a dose to a worker of 294 mrem (2.94 mSv) for a one minute 
duration, and 4 mrem (0.04 mSv) for the maximum exposed member of the 
public. The details of these calculations are provided in the NRC's SER 
that will be issued with the renewed license. The occupational 
radiation doses resulting from the postulated MHA would be well below 
the 10 CFR 20.1201 limit of 5,000 mrem (50 mSv). The maximum calculated 
radiation doses for members of the public resulting from the postulated 
MHA would be below the 10 CFR 20.1301 limit of 100 mrem (1 mSv).
    Because the NRC concludes in the SE that the radiological 
consequences of the MHA are within the NRC's 10 CFR part 20 dose 
limits, the proposed action will not have a significant impact with 
respect to the radiological consequences of the MHA.
Conclusions--Radiological Impacts
    As discussed previously in this notice, the applicant has requested 
a power increase from 1kW to 12 kW maximum allowed licensed power. In 
addition, as previously described, while there is a potential increase 
in routine occupational and public radiation exposure as a result of 
license renewal at the higher power level, all exposure rates and doses 
would be within regulatory limits. There would be no changes in the 
types of effluents that may be released off site, and any potential 
increase in their quantities would be within regulatory limits. The 
applicant has systems in place for controlling the release of 
radiological effluents and implements a radiation protection program to 
monitor personnel exposures and releases of radioactive effluents, and 
the systems and radiation protection program are appropriate for the 
types and quantities of effluents expected to be generated by continued 
operation of the reactor. The proposed action will not significantly 
increase the probability or consequences of accidents. Therefore, 
license renewal and the proposed power increase would not change the 
environmental impact of facility operation. The NRC evaluated 
information contained in the renewal application and data reported to 
the NRC by the applicant for the last 5 years of operation to determine 
the projected radiological impact of the facility on the environment 
during the period of the renewed license. The NRC found that releases 
of radioactive material and personnel exposures were all well within 
applicable regulatory limits. Based on this evaluation, the NRC 
concludes that the proposed action would not have a significant 
environmental impact.
B. Non-Radiological Impacts
    The proposed action would not result in any land use changes, 
visual resource impacts, or increases in noise. No significant changes 
in air emissions would occur as a result of the proposed license 
renewal and power increase. Because water is supplied through the city, 
the proposed action would not affect surface water or groundwater 
resources. There is no potential for the proposed action to affect 
aquatic or terrestrial resources. Therefore, the NRC concludes that the 
proposed action would have no significant non-radiological impacts.
Other Applicable Environmental Laws
    In addition to the National Environmental Policy Act (NEPA), the 
NRC has responsibilities that are derived from other environmental 
laws, which include the Endangered Species Act (ESA), Coastal Zone 
Management Act, National Historic Preservation Act (NHPA), Fish and 
Wildlife Coordination Act, and Executive Order 12898 Environmental 
Justice. Preparing this EA satisfies the agency's obligations under 
NEPA. The following presents a brief discussion of impacts associated 
with resources protected by these laws.
Endangered Species Act
    The NRC staff conducted a search of Federally listed species and 
critical habitats that have the potential to occur in the vicinity of 
the PUR-1 using the U.S. Fish and Wildlife Service's (FWS) 
Environmental Conservation Online System Information for Planning and 
Conservation (IPaC) system. Five Federally-listed mussels--clubshell 
(Pleurobema clava), fanshell (Cyprogenia stegaria), snuffbox 
(Epioblasma triquetra), rabbitsfoot (Quadrula cylindrical cylindrical), 
and sheepnose (Plethobasus cyphus)--and the Indiana bat (Myotis 
sodalis) occur in Tippecanoe County. However, none of these species are 
likely to occur near the PUR-1 because the facility is located on the 
Purdue University Campus, which has been developed since the 1960s and 
does not provide suitable habitat for Federally-listed species. 
Additionally, operation of PUR-1 has no direct nexus to the natural 
environment that would affect Federally-listed species. Accordingly, 
the NRC concludes that the proposed license renewal of the PUR-1 would 
have no effect on Federally-listed species or critical habitats. 
Federal agencies are not required to consult with the FWS if they 
determine that an action will not affect listed species or critical 
habitats (ADAMS Accession No. ML16120A505). Thus, the ESA does not 
require consultation for the proposed PUR-1 license renewal and 
proposed power uprate, and the NRC considers its obligations under ESA 
section 7 to be fulfilled for the proposed action.
Costal Zone Management Act
    Tippecanoe County, Indiana does not contain any coastal zones. 
Because the PUR-1 is not located within or near any managed coastal 
zones, the proposed action would not affect any coastal zones and 
Coastal Zone Management Act consistency certification does not apply.
National Historic Preservation Act
    The NHPA requires Federal agencies to consider the effects of their 
undertakings on historic properties. As stated in the Act, historic 
properties are any prehistoric or historic district, site, building, 
structure, or object included in, or eligible for inclusion in the 
National Register of Historic Places (NRHP). The NRHP lists several 
historic districts and properties within 0.5 miles of PUR-1 in the 
Duncan Annex of the Electrical Engineering Building on the campus of 
Purdue University. Operation of PUR-1 has not likely had any impact on 
these districts and properties. Based on this information, the NRC 
staff finds that the potential impacts of license renewal and the 
continued operation of PUR-1 would have no adverse effect on historic 
properties located near PUR-1.
Fish and Wildlife Coordination Act
    The proposed action does not involve any water resource development 
projects, including any of the modifications relating to impounding a 
body of water, damming, diverting a stream or river, deepening a 
channel, irrigation, or altering a body of water for navigation or 
drainage. Therefore, no coordination with FWS pursuant to the Fish and 
Wildlife Coordination Act is required for the proposed action.

[[Page 74826]]

Executive Order 12898--Environmental Justice
    The environmental justice impact analysis evaluates the potential 
for disproportionately high and adverse human health and environmental 
effects on minority and low-income populations that could result from 
the relicensing and the continued operation of PUR-1. Such effects may 
include human health, biological, cultural, economic, or social 
impacts.
    Minority Populations in the Vicinity of PUR-1. According to U.S. 
Census Bureau's 2010 Census, approximately 21 percent of the total 
population (approximately 164,000 individuals) residing within a 10-
mile radius of PUR-1 identified themselves as minorities. The largest 
minority population were Hispanic, Latino, or Spanish origin of any 
race at (approximately 12,800 or 8 percent), followed by Asian 
(approximately 10,700 persons or 7 percent). According to the 2010 
Census, about 20 percent of the Tippecanoe County population identified 
themselves as minorities, with persons of Hispanic, Latino, or Spanish 
origin and Asians comprising the largest minority populations 
(approximately 8 and 7 percent, respectively). According to the U.S. 
Census Bureau's 2014 American Community Survey 1-year Estimates, the 
minority population of Tippecanoe County, as a percent of the total 
population, had increased to about 22 percent.
    Low-income Populations in the Vicinity of PUR-1. According to the 
U.S. Census Bureau's 2010-2014 American Community Survey 5-Year 
Estimates, approximately 36,000 persons and 4,000 families 
(approximately 22.7 and 11.7 percent, respectively) residing within a 
10-mile radius of PUR-1 were identified as living below the Federal 
poverty threshold. The 2014 Federal poverty threshold was $24,230 for a 
family of four.
    According to the U.S. Census Bureau's 2014 American Community 
Survey Census 1-Year Estimates, the median household income for Indiana 
was $49,446, while 11 percent of families and 15.2 percent of the state 
population were found to be living below the Federal poverty threshold. 
Tippecanoe County had a lower median household income average ($45,771) 
and a higher percent of families and people living below the poverty 
level (12.2 and 23.6 percent, respectively).
    Impact Analysis. Potential impacts to minority and low-income 
populations would mostly consist of radiological effects, however, 
radiation doses from continued operations associated with the license 
renewal and the proposed power increase are expected to continue at 
current levels, and would be well below regulatory limits.
    Based on this information and the analysis of human health and 
environmental impacts presented in this EA, the proposed action would 
not have disproportionately high and adverse human health and 
environmental effects on minority and low-income populations residing 
in the vicinity of PUR-1.
Environmental Impacts of the Alternatives to the Proposed Action
    As an alternative to license renewal, the NRC considered denying 
the proposed action (i.e., the ``no-action'' alternative). If the NRC 
denied the request for license renewal, reactor operations would cease 
and decommissioning would be required. The NRC notes that, even with a 
renewed license, PUR-1 will eventually be decommissioned, at which time 
the environmental effects of decommissioning would occur. 
Decommissioning would be conducted in accordance with an NRC-approved 
decommissioning plan, which would require a separate environmental 
review under Sec.  51.21. Cessation of reactor operations would reduce 
or eliminate radioactive effluents. However, as previously discussed in 
this EA, radioactive effluents from reactor operations constitute a 
small fraction of the applicable regulatory limits. Therefore, the 
environmental impacts of license renewal, including the proposed power 
uprate, and the denial of the request for license renewal would be 
similar. In addition, denying the request for license renewal would 
eliminate the benefits of teaching, research, and services provided by 
the PUR-1 facility.
Alternative Use of Resources
    The proposed action does not involve the use of any different 
resources or significant quantities of resources beyond those 
previously considered in the issuance of Facility Operating License No. 
R-87 for the PUR-1 in August 1988, which renewed the Facility Operating 
License for a period of 20 years.
Agencies and Persons Consulted
    The NRC did not enter into consultation with any other Federal 
agencies or with the State of Indiana regarding the environmental 
impact of the proposed action. However, on October 21, 2016, the NRC 
notified the Indiana State official, Ms. Laura Dresen, Radiation 
Programs Director, of the Indiana Department of Homeland Security of 
the proposed action. The State official had no comments.

III. Finding of No Significant Impact

    The NRC is considering issuance of a renewed Facility Operating 
License No. R-87, held by Purdue University, which would authorize the 
continued operation of PUR-1 for an additional 20 years.
    On the basis of the EA included in Section II of this notice and 
incorporated by reference in this finding, the NRC concludes that the 
proposed action would not have significant effects on the quality of 
the human environment. Section IV lists the environmental documents 
related to the proposed action and includes information on the 
availability of these documents. Based on its findings, the NRC has 
decided not to prepare an environmental impact statement for the 
proposed action.

IV. Availability of Documents

    The documents identified in the following tables are available to 
interested persons as indicated.
