SUPPLEMENTARY INFORMATION: 

I. Introduction

    The NRC is considering renewal of Facility Operating License No. R-
83, held by TEES/TAMUS, which would authorize continued operation of 
its NSCR, located in College Station, Brazos County, Texas. Therefore, 
as required by Sec.  51.21 of Title 10 of the Code of Federal 
Regulations (10 CFR), the NRC performed an environmental assessment. 
Based on the results of the environmental assessment that follows, the 
NRC has determined not to prepare an environmental impact statement for 
the renewed license, and is issuing a finding of no significant impact.

II. Environmental Assessment

Description of the Proposed Action

    The proposed action would renew Facility Operating License No. R-83 
for an additional 20 years from the date of issuance of the renewed 
license. The proposed action is in accordance with the licensee's 
letter dated February 27, 2003, as supplemented by letters dated July 
22, 2009; July 28, August 30, August 31, and December 9, 2010; May 27, 
June 9, and November 21, 2011; January 12, April 11, and November 14, 
2012; January 31, 2013; February 3, February 11, and November 13, 2014; 
and March 2, June 5, June 11, and June 30, 2015 (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 TEES/TAMUS NSCR to routinely provide teaching, research, and 
services to numerous institutions for a period of 20 years.

Environmental Impacts of the Proposed Action

    The NRC has completed its safety evaluation of the proposed action 
to issue a renewed TEES/TAMUS NSC Facility Operating License No. R-83 
to allow continued operation of the TEES/TAMUS NSCR for an additional 
20 years and concludes there is reasonable assurance that the licensee 
will continue to operate the TEES/TAMUS NSCR safely for the additional 
period of time. The details of the NRC's safety evaluation will be 
provided with the renewed license that will be issued as part of the 
letter to the licensee approving its license renewal application. This 
document contains the environmental assessment of the proposed action.
    The TEES/TAMUS NSC is located on a rectangular 6-acre site on the 
west end of the Texas A&M University (TAMU) campus in College Station, 
Texas. The NSC is located 460 meters (1500 feet) west of the north-
south runway of Easterwood Airport. The NSC is surrounded by land owned 
and controlled by TAMU and Easterwood Airport. No industrial, 
transportation or military facilities within the vicinity of the NSC 
pose sufficient risk to the NSC NSCR to render the site unusable for 
operation of the reactor facility. Although the airport is nearby, the 
trajectory of the runways make the probability of a casualty resulting 
from an aircraft collision low. The NSCR is located within a steel and 
concrete confinement building, below ground level, and is protected by 
thick stainless steel-lined concrete pool walls, which would minimize 
the radiological risk of a potential aircraft collision.
    The NSC is comprised of the reactor confinement building, entry/
reception area, laboratory building and other equipment rooms, and 
storage/support buildings. The main entrance into the NSC is located at 
the east end of the site. The NSC is located 9.6 kilometers (6 miles) 
south of the city center of Bryan, 4.8 kilometers (3 miles) southwest 
of the TAMU main campus, and 4.1 kilometers (2.5 miles) west-southwest 
of the City of College Station. The nearest permanent residences are 
greater than 1 kilometer (0.6 miles) from the NSC and the nearest 
dormitories are 4 to 6 kilometers (2.5 to 3.5 miles) away.
    The NSC is approximately 6 kilometers (3.5 miles) south of TAMU's 
Zachry Engineering Center complex. The Zachry Engineering Center is the 
location of TAMU's second research reactor, an Aerojet General 
Nucleonics (AGN)-201M research reactor (the AGN). The license for the 
AGN is currently under review for renewal which will also include an 
environmental assessment similar in nature to this environmental 
assessment for the NSC.
    The NSCR is a pool-type, light water moderated and cooled TRIGA 
research reactor licensed to operate at a steady-state power level of 
1.0 megawatt (thermal). The reactor is also licensed to operate in a 
pulse mode. The fuel is located at the bottom of a stainless steel-
lined concrete pool, which has two sections with a total volume of 
401,500 liters (106,000 gallons) of water. The main section of the pool 
is 10 meters (33 feet) deep and 5.5 meters (18 feet) wide. The stall 
section of the pool is 2.8 meters (9 feet) wide with a rounded end, 
which can be isolated from the main section of the pool by an aluminum 
gate. The reactor is fueled with standard TRIGA low-enriched uranium 
fuel and the core is normally covered by 8 meters (26 feet) of water. A 
detailed description of the reactor is publicly available and can be 
found in the Safety Analysis Report (SAR) for the NSCR. There have been 
two major modifications to Facility Operating License No. R-83 since 
the last renewal of the license on March 30, 1983. An order was issued 
in 2006 amending the license by: (1) Allowing an increase in the 
possession limits for uranium-235 to bring a low-enriched uranium core 
on site for converting the reactor from the use of high-enriched 
uranium fuel to low-enriched uranium fuel (possession limits were 
reduced when the high-enriched uranium core was removed from the 
facility after conversion); and (2) converting the reactor from the use 
of high-enriched uranium fuel to low-enriched uranium fuel.
A. Radiological Impact
    Environmental Effects of Reactor Operations:
    Gaseous radioactive effluents are discharged from the NSCR facility 
exhaust system through a single release point, a 26-meter (85 feet) 
high building stack, at a volumetric flow rate of approximately 233 
cubic meters (8,000 cubic feet) per minute. The only significant 
radionuclide found in the gaseous effluent stream is argon-41 (Ar-41). 
The Ar-41 release rate for the NSCR is limited to 30 curies per year 
(Ci/yr), as required by TS 3.5.2.

[[Page 53345]]

    The licensee states that all modes of operation at the NSCR, 
including thermal column operations, produce air concentrations and 
total Ar-41 release much less than the TS 3.5.2 limit of 30-Ci/yr. 
However, using the 30-Ci/yr TS 3.5.2 limit and the stack flow rate 
provided above, the licensee calculated that the average Ar-41 release 
concentration would be 2.5x10-7 microcuries per milliliter 
([mu]Ci/mL), which is 8.3 percent of the derived air concentration 
(DAC) limiting value of 3x10-6 [mu]Ci/mL, established in 
Table 1 of appendix B, ``Annual Limits on Intake (ALIs) and Derived Air 
Concentrations (DACs) of Radionuclides for Occupational Exposure; 
Effluent Concentrations; Concentrations for Release to Sewerage,'' to 
10 CFR part 20. Using the building concentration as the average stack 
flow concentration provided above, the licensee calculated the 
occupational dose to an NSC worker staying in the confinement for 2,000 
hours per year at 416 millirem (mrem). The license also evaluated the 
dose to a worker given the assumption that the concentration of Ar-41, 
based on the 30 Ci/yr release limit, was generated during 2,000 hours 
of reactor operation and the resulting dose was 1.84 rem, which is well 
below the 5,000 mrem limit established in Sec.  20.1201, ``Occupational 
dose limits for adults.''
    The licensee calculated, using an atmospheric dilution factor of 5 
x 10-3 for the distance to the fence line at 100 m (boundary 
of the restricted area), the potential dose to a member of the public 
to be 12.6 mrem for a continuous Ar-41 exposure over the entire year. 
This dose value is below the limit of 100 mrem/yr in Sec.  20.1301, 
``Dose limits for individual members of the public.'' In order to 
ensure that the actual dose remains below the 10 mrem annual as low as 
is reasonably achievable (ALARA) constraint of Sec.  20.1101, 
``Radiation protection programs,'' the licensee indicated that the Ar-
41 releases are monitored monthly, and the Radiation Safety Officer 
(RSO) reviews the results of any abnormal releases to ensure that the 
Ar-41 doses remain below the 10 mrem ALARA constraint. Additionally, a 
review of the Ar-41 releases from the licensee's annual reports shows 
that the annual release of Ar-41 is well below the 30 Ci limit. The 
2013 Annual Report, as supplemented, is publicly available and 
indicated that the total release of Ar-41 was 10.4 Ci. The NRC 
estimates this release could result in a potential dose to a member of 
the public to be approximately 4.3 mrem over a year.
    The licensee disposes of liquid radioactive wastes by discharge to 
the sanitary sewer. Liquid radioactive waste is collected from various 
locations within the facility and transferred to one of three 140,060 
liters (37,000 gallons) hold-up tanks. When a tank is full, its 
contents are filtered to remove any particulates, and sampled for 
radioactive content. Procedures are used to control the discharge 
process to ensure that discharges meet the requirements of Sec.  
20.2003, ``Disposal by release into sanitary sewerage,'' for disposal 
into the sanitary sewerage. For many years, the licensee discharged 
liquid waste from the hold-up tanks directly to a small creek running 
through the site. The waste was analyzed and sufficiently diluted 
before each release. Sampling of creek sediment was routinely done as 
part of the overall environmental monitoring program. In September 
2008, the licensee reconfigured its liquid effluent system such that 
the hold-up tanks now discharge to the sanitary sewer. Since that time, 
no releases have been made to the creek and none are planned.
    The licensee oversees the handling of solid low-level radioactive 
waste generated at the NSC. The bulk of the waste consists of gloves, 
paper, plastic, and small pieces of metal. The licensee disposes of the 
waste by decay-in-storage or shipment to a low-level waste broker in 
accordance with all applicable regulations for transportation of 
radioactive materials.
    To comply with the Nuclear Waste Policy Act of 1982, the licensee 
has entered into a contract with the U.S. Department of Energy (DOE) 
that provides that DOE retains title to the fuel utilized at the NSC 
and that DOE is obligated to take the fuel from the site for final 
disposition.
    As described in Chapter 11 of the publicly available NSC SAR, 
personnel exposures are well within the limits set by Sec.  20.1201, 
``Occupational dose limits for adults,'' and are ALARA. The licensee 
tracks exposures of personnel monitored with dosimeters, which are 
usually less than 10 percent of the occupational limit of 50 
milliSieverts (5,000 mrem) per year. Area thermo-luminescent dosimeter 
(TLD) monitors mounted in the control room and other strategic 
locations provide an additional monthly measurement of total radiation 
exposures at those locations. No changes in reactor operation that 
would lead to an increase in occupational dose are expected as a result 
of the proposed action.
    The licensee conducts an environmental monitoring program to assess 
the radiological impact of reactor operations on the surrounding areas. 
The program consists of measuring and recording the integrated 
radiation exposure obtained from environmental TLDs located at various 
positions around the site boundary and at two control locations away 
from any direct influence from the NSC. The licensee administers the 
program and maintains the appropriate records. Over the past five 
years, the survey program indicated that radiation exposures at the 
monitoring locations were not significantly higher than those measured 
at the control locations. Year-to-year trends in exposures are 
consistent between monitoring locations. Also, no correlation exists 
between total annual reactor operation and annual exposures measured at 
the monitoring locations. Based on its review of the past five years of 
data, the NRC staff concludes that operation of the NSC does not have 
any significant radiological impact on the surrounding environment. No 
changes in reactor operation that would affect off-site radiation 
levels are expected as a result of the proposed action.

Environmental Effects of Accidents

    Accident scenarios are discussed in Chapter 13 of the NSC SAR. The 
maximum hypothetical accident is the simultaneous loss of coolant and 
rupture of a single fuel element in air. The licensee conservatively 
calculated doses to facility personnel and the maximum potential dose 
to a member of the public. The NRC performed independent calculations 
to verify that the doses represent conservative estimates for the 
maximum hypothetical accident. Occupational doses resulting from this 
accident would be well below the 10 CFR part 20 annual limit of 50 
milliSievert (5.0 rem). Maximum doses for members of the public 
resulting from this accident would be well below the 10 CFR part 20 
annual limit of 1.0 milliSievert (100 mrem). The proposed action will 
not increase the probability or consequences of accidents.
    The licensee has not requested any changes to the facility design 
or operating conditions as part of the application for license renewal. 
No changes are being made in the types or quantities of effluents that 
may be released off site. The licensee 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. As discussed in the safety 
evaluation, the systems and radiation protection program are 
appropriate for the types and quantities of effluents expected to be 
generated by continued operation of the NSCR. Accordingly, there would 
be

[[Page 53346]]

no increase in routine occupational or public radiation exposure as a 
result of license renewal. As discussed in the safety evaluation, the 
proposed action would not significantly increase the probability or 
consequences of accidents. Therefore, license renewal would not change 
the environmental impact of facility operation. The NRC evaluated 
information contained in the licensee's renewal application and 
reviewed data reported to the NRC by the licensee for the last five 
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 its evaluation, the NRC concludes that continued operation of 
the NSCR would not have a significant environmental impact.
B. Non-Radiological Impacts
    The NSCR core is cooled by a light water primary system consisting 
of the reactor pool, a heat removal system, and a processing system. 
Cooling occurs by natural convection with the heated coolant rising out 
of the core and into the bulk pool water. The large heat sink provided 
by the volume of primary coolant allows several hours of full-power 
operation without any secondary cooling. The heat removal system 
transfers heat to the secondary system via a heat exchanger. The 
secondary system uses water supplied by the municipal water system. The 
licensee monitors both systems for purity and to detect significant 
leakage. The licensee does not chemically treat the primary coolant. 
Three chemicals (sulfuric acid, sodium hypochlorite (bleach), and a 
commercial cooling water treatment) are used to maintain the secondary 
coolant pH, control growth of organisms, and control the buildup of 
scale, respectively. These chemicals are highly diluted and possess 
minimal hazards to the operating staff. Secondary cooling tower water 
is occasionally ``blown-down'' to maintain acceptable conductivity 
(purity), and the blow-down water is disposed of in accordance with the 
permit limits of the University's waste water treatment plant. The 
licensee uses small volumes of standard laboratory-grade chemicals in 
their chemical laboratories. These chemicals are disposed through an 
established procedure with the University's Environmental Health 
Office. The licensee implements a non-radiological environmental 
monitoring program with the Texas Department of State Health Services. 
This program helps to ensure that impacts are kept within acceptable 
limits.
    Given that the proposed action does not involve any change in the 
operation of the reactor, the minimal heat load dissipated to the 
environment and limited chemical usage, the NRC concludes that the 
proposed action will not have a significant non-radiological impact on 
the environment.

National Environmental Policy Act Considerations

    The NRC has responsibilities that are derived from the National 
Environmental Policy Act and 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 (FWCA) and Executive Order 12898--Environmental 
Justice. The following presents a brief discussion of impacts 
associated with these laws and other requirements.
    1. Endangered Species Act
    No effects on the aquatic or terrestrial habitat in the vicinity of 
the NSC, or to threatened, endangered, or protected species under the 
ESA, would be expected.
    2. Coastal Zone Management Act
    The NSC is not located within any managed coastal zone, nor would 
the effluents and emissions from the NSCR impact any managed coastal 
zones.
    3. National Historic Preservation Act
    The NHPA requires Federal agencies to consider the effects of their 
undertakings on historic properties. The National Register of Historic 
Places lists several historical sites in Brazos County. However, none 
of the sites are located within 1 kilometer (0.6 miles) of the NSC and, 
given their respective locations, continued operation of the NSCR will 
not impact any historical sites. The NRC staff contacted the State of 
Texas Historical Preservation Officer (SHPO) and discussed the proposed 
action. The SHPO indicated that there was no objection to the proposed 
action and that it did not require a formal review by that office. 
Based on this information, the NRC staff finds that the potential 
impacts of the proposed action would have no adverse effect on historic 
and archaeological resources.
    4. Fish and Wildlife Coordination Act
    With regard to the NSC, TEES/TAMUS is not planning any water 
resource development projects, including any 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, this action has no significant 
impact related to the FWCA.
    5. 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 the NSC. Such effects 
may include human health, biological, cultural, economic, or social 
impacts.
    Minority Populations in the Vicinity of the NSC--According to the 
2010 census data, 36 percent of the total population (approximately 
512,000 individuals) residing within a 50-mile radius of the NSC 
identified themselves as minority individuals. The largest minority 
were people of Hispanic, Latino, or Spanish origin of any race 
(approximately 100,000 persons or 19.5 percent), followed by Black or 
African American (65,000 or 12.7 percent). According to the U.S. Census 
Bureau, about 41 percent of the Brazos County population identified 
themselves as minorities, with persons of Hispanic, Latino, or Spanish 
origin comprising the largest minority group (23 percent). According to 
U.S. Census Bureau's 2013 American Community Survey 1-Year Estimates, 
the minority population of Brazos County, as a percent of the total 
population, had increased to about 42 percent.
    Low-income Populations in the Vicinity of the NSC--According to the 
U.S. Census Bureau's 2008-2012 American Community Survey 5-Year 
Estimates, approximately 100,000 individuals (20 percent) residing 
within a 50-mile radius of the NSC were identified as living below the 
Federal poverty threshold. The 2012 Federal poverty threshold was 
$23,492 for a family of four.
    According to the U.S. Census Bureau's 2013 American Community 
Survey 1-Year Estimates, the median household income for Texas was 
$51,704, while 13.6 percent of families and 17.5 percent of the state 
population were found to be living below the Federal poverty threshold. 
Brazos County had a lower median household income average ($37,913) and 
a higher percent of families (16.1 percent) and individuals (29.5 
percent) living below the poverty level, 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 are expected to

[[Page 53347]]

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 environmental assessment, the 
proposed license renewal would not have disproportionately high and 
adverse human health and environmental effects on minority and low-
income populations residing in the vicinity of the NSC.

Environmental Impacts of the Alternatives to the Proposed Action

    As an alternative to license renewal, the NRC considered denying 
the proposed action. If the NRC denied the request for license renewal, 
reactor operations at the NSC would cease and decommissioning would be 
required. The NRC notes that, even with a renewed license, the NSC will 
eventually require decommissioning, 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, 
``Criteria for and identification of licensing and regulatory actions 
requiring environmental assessments.'' Cessation of reactor operations 
at the NSC would reduce or eliminate radioactive effluents and 
emissions. However, as previously discussed in this environmental 
assessment, radioactive effluents resulting from reactor operations are 
only a small fraction of the applicable regulatory limits. Therefore, 
the environmental impacts of renewing the license 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 NSCR.

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 License Amendment No. 9 to 
Facility Operating License No. R-83 for the NSC dated March 30, 1983, 
which renewed the Facility Operating License No. R-83 for an additional 
period of 20 years.

Agencies and Persons Consulted

    In accordance with the agency's stated policy, on June 11, 2010, 
the NRC staff consulted with the Texas State Liaison Officer regarding 
the environmental impact of the proposed action. The consultation 
involved a thorough explanation of the environmental review, the 
details of this environmental assessment, and the NRC's findings. The 
State official stated the he understood the NRC review and had no 
comments regarding the proposed action.

III. Finding of No Significant Impact

    The NRC staff has prepared this EA as part of its review of the 
proposed action. On the basis of this EA, the NRC finds that there are 
no significant environmental impacts from the proposed action, and that 
preparation of an environmental impact statement is not warranted. On 
the basis of the environmental assessment included in Section II of 
this document, the NRC concludes that the proposed action will not have 
a significant effect on the quality of the human environment. 
Accordingly, the NRC has determined that a finding of no significant 
impact is appropriate.
