NUCLEAR REGULATORY COMMISSION

[Docket Nos. 50-289 and 50-320; NRC-2017-0146]


Exelon Generation Company, LLC; Three Mile Island Nuclear 
Station, Units 1 and 2

AGENCY: Nuclear Regulatory Commission.

ACTION: Environmental assessment and finding of no significant impact; 
issuance.

-----------------------------------------------------------------------

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is considering 
issuance of an amendment to Renewed Facility Operating License No. DPR-
50 held by Exelon Generation Company, LLC (Exelon, the licensee) for 
the operation of Three Mile Island Nuclear Station (TMI), Units 1 and 
2, located in Dauphin County, Pennsylvania. The proposed amendment 
would allow for changes to TMI's Radiological Emergency Plan Annex 
staffing levels to align with Exelon's standard fleet Emergency 
Response Organization (ERO) framework. In accordance with the 
Possession-Only License No. DPR-73 Post-Defueling Monitored Storage 
Safety Analysis Report for TMI, Unit 2, the emergency plan for Unit 1 
is considered to encompass Unit 2. Therefore, an amendment to the Unit 
2 license is not required. The NRC is issuing an environmental 
assessment (EA) and finding of no significant impact (FONSI) associated 
with the proposed license amendment.

DATES: The EA referenced in this document is available on June 22, 
2017.

SUPPLEMENTARY INFORMATION: 

I. Introduction

    The NRC is considering issuance of a license amendment pursuant to 
section 50.54 of title 10 of the Code of Federal Regulations (10 CFR), 
``Conditions of licenses,'' paragraph (q), ``Emergency plans,'' to 
Renewed Facility Operating License No DPR-50 held by Exelon for the 
operation of TMI, Units 1 and 2, located in Dauphin County, 
Pennsylvania. In accordance with 10 CFR 51.21, the NRC performed the 
following EA that analyzes the environmental impacts of the proposed

[[Page 28539]]

licensing action. Based on the results of this EA, and in accordance 
with 10 CFR 51.31(a), the NRC has determined not to prepare an 
environmental impact statement for the proposed licensing action, and 
is issuing a FONSI.

II. Environmental Assessment

Description of the Proposed Action

    The proposed action would revise the Radiological Emergency Plan 
Annex for TMI in order to allow changes to staffing levels to align 
with Exelon's standard fleet ERO framework. The proposed changes would 
decrease the on-shift radiation protection technician staffing from 
three to two technicians. The proposed amendment would also make 
changes to the staffing of on-shift maintenance personnel. 
Specifically, the amendment would: (1) Revise the on-shift position of 
operations support center director (renamed repair team lead) to remove 
the requirement that the position be from the maintenance organization; 
(2) remove two dedicated maintenance technicians from the on-shift 
staffing total; and (3) remove two additional personnel from the repair 
and corrective actions major task and assign them to respond within 60 
minutes, as well as one additional staff person to respond within 90 
minutes.
    The proposed action is in accordance with the licensee's 
application dated July 15, 2016 (ADAMS Package Accession No. 
ML16201A306), as supplemented by letter dated February 13, 2017 (ADAMS 
Accession No. ML17045A036).

Need for the Proposed Action

    Nuclear power plant owners, government agencies, and state and 
local officials work together to create a system for emergency 
preparedness and response that will serve the public in the unlikely 
event of an emergency. An effective emergency preparedness program 
decreases the likelihood of an initiating event at a nuclear power 
reactor proceeding to a severe accident. Emergency preparedness cannot 
affect the probability of the initiating event, but a high level of 
emergency preparedness increases the probability of accident mitigation 
if the initiating event proceeds beyond the need for initial operator 
actions.
    Each licensee is required to establish emergency plans to be 
implemented in the event of an accident. These emergency plans, in 
part, cover preparations for evacuation, sheltering, and other actions 
to protect individuals near plants in the event of an accident.
    The NRC, as well as other Federal and state regulatory agencies, 
reviews emergency plans to ensure that the condition of emergency 
preparedness provides reasonable assurance that adequate protective 
measures can and will be taken in the event of a radiological 
emergency.
    Separate from this environmental assessment, the NRC staff is 
performing a safety assessment of Exelon's proposed changes to the 
emergency plan for TMI. This safety review will be documented in a 
safety evaluation report. The safety evaluation report will determine 
whether, with the proposed changes to the emergency plan for TMI, there 
continues to be reasonable assurance that adequate protective measures 
can and will be taken in the event of a radiological emergency at TMI, 
in accordance with the standards of 10 CFR 50.47(b) and the 
requirements in appendix E to 10 CFR part 50.
    The proposed action is needed to align TMI's Radiological Emergency 
Plan Annex staffing levels with Exelon's standard fleet ERO framework. 
This will improve consistency throughout the Exelon fleet regarding the 
application of operating experience and process improvements from other 
Exelon fleet sites and will provide flexibility in staffing ERO 
positions with qualified personnel from either the operations or 
maintenance organizations.

Environmental Impacts of the Proposed Action

    The NRC staff has completed its evaluation of the environmental 
impacts of the proposed action.
    The proposed action consists mainly of administrative changes 
related to the staffing levels and positions of the TMI emergency plan. 
These changes include (a) decreasing radiation protection technician 
staffing from three to two technicians, (b) renaming the on-shift 
``operations support center director'' to ``repair team lead'' and 
removing the requirement that the position be filled by a ``maintenance 
team lead,'' (c) removing two dedicated maintenance technicians from 
the on-shift staffing total, (d) removing one Mechanical and one 
Electrical/Instrumentation and Control Maintenance Technician assigned 
concurrent duties, and (e) adding one Mechanical Maintenance Technician 
and one Electrical Maintenance Technician as 60-minute augmentation 
responders and one Maintenance Instrumentation and Control Technician 
as a 90-minute augmentation responder.
    With regard to potential non-radiological environmental impacts, 
the proposed changes would have no direct impacts on land use or water 
resources, including terrestrial and aquatic biota, as they involve no 
new construction or modification of plant operational systems. There 
would be no changes to the quality or quantity of non-radiological 
effluents and no changes to the plant's National Pollutant Discharge 
Elimination System permit are needed. Changes in staffing levels could 
result in minor changes in vehicular traffic and associated air 
pollutant emissions, but no significant changes in ambient air quality 
would be expected from the proposed changes. In addition, there would 
be no noticeable effect on socioeconomic conditions in the region, no 
environment justice impacts, and no impacts to historic and cultural 
resources from the proposed changes. Therefore, there are no 
significant non-radiological environmental impacts associated with the 
proposed action.
    With regard to potential radiological environmental impacts, if the 
NRC staff's safety review of the proposed changes to the TMI emergency 
plan determines that, with the proposed changes, the emergency plan 
continues to meet the standards of 10 CFR 50.47(b) and the requirements 
in appendix E to 10 CFR part 50, then the proposed action would not 
increase the probability or consequences of radiological accidents. 
Additionally, the NRC staff has concluded that the proposed changes 
would have no direct radiological environmental impacts. There would be 
no change to the types or amounts of radioactive effluents that may be 
released and, therefore, no change in occupational or public radiation 
exposure from the proposed changes. Moreover, no changes would be made 
to plant buildings or the site property from the proposed changes. 
Therefore, there are no significant radiological environmental impacts 
associated with the proposed action.

Environmental Impacts of the Alternatives to the Proposed Action

    As an alternative to the proposed action, the NRC staff considered 
denial of the proposed action (i.e., the ``no-action'' alternative). 
Denial of the license amendment request would result in no change in 
current environmental impacts. Accordingly, the environmental impacts 
of the proposed action and the no-action alternative are similar.

Alternative Use of Resources

    The proposed action does not involve the use of any different 
resources than those previously considered.

Agencies and Persons Consulted

    No additional agencies or persons were consulted regarding the

[[Page 28540]]

environmental impact of the proposed action.

III. Finding of No Significant Impact

    Pursuant to 10 CFR 50.54(q), the licensee has requested a license 
amendment to Renewed Facility Operating License No. DPR-50 for the 
operation of TMI to allow staffing changes to the Radiological 
Emergency Plan Annex for TMI. The NRC is considering issuing the 
requested amendment. On the basis of the EA included in Section II of 
this document and incorporated by reference into this finding, the NRC 
concludes that the proposed action would not have a significant effect 
on the quality of the human environment. Accordingly, the NRC has 
determined not to prepare an environmental impact statement for the 
proposed action.
    The related environmental document is NUREG-1437, ``Generic 
Environmental Impact Statement for License Renewal of Nuclear Plants, 
Supplement 37, Regarding Three Mile Island Nuclear Station, Unit 1, 
Final Report,'' and is available for public inspection at ADAMS 
Accession No. ML091751063. NUREG-1437, Supplement 37, provides the 
latest environmental review of current operations and a description of 
environmental conditions at TMI.
