SUMMARY
DESCRIPTION The proposed change revises Salem Generating Station Units 1 and 2 (Salem) Technical Specification (TS) 3/4.8.1.1 to remove the required actions for load testing operable Emergency Diesel Generators (EDGs) when another EDG and/or offsite circuits are inoperable. As part of this change, the current TS Surveillance Requirement (SR) 4.8.1.1.2.a.2, which combines the EDG starting test and the load-run test, is split into two separate SRs. TS 3.8.1.1, Actions c and e, will be revised for consistency with the extended EDG Allowed Outage Time (AOT) approved in Amendment Nos. 346 and 327. TS 3.8.1.1 Actions c and e are also restructured for enhanced clarity and alignment with the intent of NUREG-1431 (Reference 1).
2.0 DETAILED DESCRIPTION 2.1 System Design and Operation The Salem offsite Alternating Current (AC) power supply for station startup, normal operation, and safe shutdown is supplied from the PJM Regional Transmission Organization transmission network. Offsite power is supplied to Salem from three physically independent, 500-kV circuits designed and located to minimize the likelihood of simultaneous failure. There are two physically independent circuits between the off-site transmission network and the on-site Class 1E distribution system.
The 4160-V (4-kV) distribution system for each unit includes three vital buses supplying engineered safeguards equipment. The standby AC power source for each vital bus consists of an EDG that is automatically started by accident initiation logic or on detection of a loss of offsite power. Any two of the EDGs and their associated vital buses can supply sufficient power for operation of the required safeguards equipment for a design basis Loss of Coolant Accident (LOCA) coincident with a loss of offsite power. Sufficient redundancy is provided in the safety features and their assignment to the vital buses so that failure to energize any one vital bus does not prevent operation of the required minimum safety equipment.
2.2 Current Technical Specifications Requirements TS SR 4.8.1.1.2.a.2 contains the EDG starting test and load-run test in a single SR:
Each diesel generator shall be demonstrated OPERABLE:
a.
In accordance with the Surveillance Frequency Control Program by:
2.
Verifying the diesel generator starts from standby conditions* and achieves 3910 volts and 58.8 Hz in 13 seconds, and subsequently achieves steady state voltage of 3910 and 4400 volts and frequency of 60 +/- 1.2 Hz.
Subsequently, verifying the generator is synchronized with voltage maintained 3910 and 4580 volts, gradually loaded to 2340-2600 kw**,
and operates at a load of 2340-2600 kw for greater than or equal to 60 minutes.
LR-N25-0053 LAR S22-06 Enclosure 2
The SR is modified by two Notes; one permitting testing to be conducted in accordance with the manufacturer's recommendations regarding engine pre-lube, warm-up and loading (unless loading times are specified in the individual SRs); and the second clarifying that the loading band is meant as guidance to preclude routine exceedances of the EDG manufacturer's design ratings, and that loads in excess of this band for special testing or momentary variations due to changing bus loads shall not invalidate the test.
With one EDG inoperable in MODES 1, 2, 3 and 4, TS 3.8.1.1, Action b.3 requires the operable EDGs to be tested in accordance with SR 4.8.1.1.2.a.2 unless specified conditions are met:

2.3 Reason for the Proposed Change The changes are consistent with the NRC guidance and recommendations provided in NUREG-1366, "Improvements to Technical Specifications Surveillance Requirements," Generic Letter (GL) 93-05, "Line-Item Technical Specifications Improvements to Reduce Surveillance Requirements for Testing" (References 2 and 3) and NUREG-1431, Revision 5, "Standard Technical Specifications, Westinghouse Plants" (Reference 1).
The EDG starting test and load-run test are currently combined into the single SR 4.8.1.1.2.a.2.
Splitting the current SR into two separate SRs is consistent with SR 3.8.1.2 and SR 3.8.1.3 in Reference 1, and is necessary to accommodate the proposed changes to TS 3.8.1.1, Action b.31.
The current requirement in TS 3.8.1.1, Action b.3, to perform the one-hour load-run test requires the operable EDGs to be synchronized with an offsite source, placing demands on plant operating personnel that can lessen the focus on the actions needed to restore the inoperable EDG to operable status. In addition, while operating in parallel with an offsite source, the operable EDGs are susceptible to perturbations in the offsite power system when the number of onsite power sources to the vital buses is already reduced.
With one offsite circuit and one EDG inoperable, TS 3.8.1.1, Action c, requires demonstrating the operability of the remaining operable EDGs by performing SR 4.8.1.1.2.a.2 within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />.
The required action places demands on plant operating personnel that can lessen the focus on the actions needed to restore the inoperable EDG or offsite circuit to operable status. While operating in parallel with an offsite source, the operable EDGs are again susceptible to perturbations in the offsite power system when the number of onsite power sources to the vital buses is already reduced. In addition, if the inoperable EDG is inoperable due to a planned maintenance outage of up to 14 days, once the inoperable offsite source is restored to operable status, the inoperable EDG should be able to be restored within the remainder of its extended AOT per TS 3.8.1.1, Action b.4.a)2, in lieu of the fixed 72-hour time frame currently identified in TS 3.8.1.1, Action c. Similarly, in TS 3.8.1.1, Action e, after the restoration of two of the EDGs, the remaining inoperable EDG should be able to be restored within the remainder of its extended AOT per TS 3.8.1.1, Action b.4.a)2, in lieu of the fixed 72-hour timeframe currently identified.
1 The Salem EDGs do not have the capability to gradually accelerate to no-load conditions, as is allowed by SR 3.8.1.2. Thus, Salem SR 4.8.1.1.2.a.2 is commensurate with SR 3.8.1.7 in Reference 1. However, the Bases for SR 3.8.1.2 in Reference 1 state that SR 3.8.1.7 is more restrictive than, and may be performed in lieu of, SR 3.8.1.2. Thus, Salem SR 4.8.1.1.2.a.2 is also commensurate with SR 3.8.1.2 in Reference 1. Therefore, SR 3.8.1.2 is referenced in this request for consistency with LCO 3.8.1, Required Action B.3.2.
LR-N25-0053 LAR S22-06 Enclosure 4
With both offsite circuits inoperable, TS 3.8.1.1, Action d.1, requires starting and loading the operable EDGs within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />. In GL 93-05, the NRC staff recognized that removing the requirement to test EDGs with both offsite circuits inoperable can improve safety, decrease equipment degradation, and eliminate an unnecessary burden on personnel resources.
The current format of TS 3.8.1.1 Actions c and e leaves room for potential ambiguity with regard to the proper actions should the first requirements listed fail to be met. This change will restructure Actions c and e to enhance clarity and align with the intent of NUREG-1431.
2.4 Description of the Proposed Change Additions are shown in double underline and deletions are shown as a strikethrough.
While no changes are being made to the text of TS 3.8.1.1, Action b.3, the effect of dividing the current SR 4.8.1.1.2.a.2 into two separate SRs will be to remove the requirement to perform the one-hour loaded-run test for the operable EDGs when one EDG is inoperable.
The current SR 4.8.1.1.2.a.2 will be divided into two separate SRs, 4.8.1.1.2.a.2 and new SR 4.8.1.1.2.a.4:
Each diesel generator shall be demonstrated OPERABLE:
- a.
In accordance with the Surveillance Frequency Control Program by:
- 2.
Verifying the diesel generator starts from standby conditions* and achieves 3910 volts and 58.8 Hz in s 13 seconds, and subsequently achieves steady state voltage of 3910 and 4400 volts and frequency of 60 +/- 1.2 Hz.
- 4.
Verifying the generator is synchronized with voltage maintained 3910 and 4580 volts, gradually loaded to 2340-2600 kw**, and operates at a load of 2340-2600 kw for greater than or equal to 60 minutes.
An allowance in SR 4.8.1.1.2.c which currently refers to SR 4.8.1.1.2.a.2 will be revised to refer to both SRs 4.8.1.1.2.a.2 and new 4.8.1.1.2.a.4:
- c.
In accordance with the Surveillance Frequency Control Program by verifying the diesel generator starts from standby conditions* and achieves 3910 volts and 58.8 Hz in 13 seconds, and subsequently achieves steady state voltage of 3910 and 4400 volts and frequency of 60 +/- 1.2 Hz.
The generator shall be synchronized to its emergency bus with voltage maintained 3910 and 4580 volts, loaded to 2340-2600** kw in less than or equal to 60 seconds, and operate at a load of 2340-2600 kw for at least 60 minutes.
This test, if it is performed so it coincides with the testing required by Surveillance Requirements 4.8.1.1.2.a.2 and 4.8.1.1.2.a.4, may also serve to concurrently meet those requirements.
LR-N25-0053 LAR S22-06 Enclosure 5
TS 3.8.1.1, Action c, will be divided into four steps. The requirement to demonstrate the operability of the remaining operable EDGs by performing SR 4.8.1.1.2.a.2 within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> will be removed. The restructuring will provide clarification as to the actions to take should the specified requirements not be met. Action c.3 will refer back to Actions a and b, potentially allowing use of the extended AOT, rather than preserving the original 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> requirement:

3.0 TECHNICAL EVALUATION
3.1 Change to SR 4.8.1.1.2.a.2 Splitting the current combined start and load-run requirement in SR 4.8.1.1.2.a.2 into two separate SRs is consistent with the presentation of separate SRs 3.8.1.2 (start) and 3.8.1.3 (load-run) in NUREG-1431. The proposed change is administrative in nature. It is intended to accommodate the remaining proposed changes within the TS and does not affect any of the current SR acceptance criteria.
3.2 Change to TS 3.8.1.1, Action b.3 Eliminating the requirement in TS 3.8.1.1, Action b.3, to perform the one-hour load run test for the operable EDGs when one EDG is inoperable is consistent with NUREG-1431, TS 3.8.1, Required Action B.3.2. As noted in the NUREG-1431 Bases, when the cause of the initial inoperable EDG cannot be confirmed not to exist on the remaining EDGs, performance of the start test suffices to provide assurance of continued operability of operable EDGs.
Loading the operable EDGs requires that they be paralleled with an offsite power source, making them vulnerable to perturbations in the offsite power system and creates a potential for losing the operable EDGs at a time when the number of onsite power sources to the vital buses has already been reduced. The additional requirement for loading the remaining operable EDGs also presents an additional burden to operations personnel that are focused on actions to restore the EDG to operable status.
LR-N25-0053 LAR S22-06 Enclosure 7
3.3 Change to TS 3.8.1.1, Action c Restructuring TS 3.8.1.1, Action c, removes ambiguity as to the actions that must be taken if the specified requirements are not met, and better aligns the action with the intent of NUREG-1431.
Removing the TS 3.8.1.1, Action c, requirement to start and load the operable EDGs within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> when one offsite circuit and one EDG are inoperable is consistent with the required actions for NUREG-1431, TS 3.8.1, Condition D. If the inoperable offsite circuit or the inoperable EDG is restored to operable status before the unit is required to be in COLD SHUTDOWN, the proposed TS 3.8.1.1, Action c.3, requires the other AC power source (offsite circuit or EDG) to be restored to operable status in accordance with the provisions of TS 3.8.1.1, Action a or b, as appropriate, with the time requirement of that action based on the time of initial loss of the remaining inoperable AC power source.
If the EDG remained inoperable after the offsite circuit was restored to operable status, the provisions of TS 3.8.1.1, Action b are required to be completed, with the completion times based on the time the EDG became inoperable. Proposed TS 3.8.1.1 Action c.3 removes an inconsistency regarding restoration of the inoperable EDG within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> from time of initial loss if the extended 14 day AOT of TS 3.8.1.1 Action b.4.a)2 was entered. TS 3.8.1.1, Action b includes performance of SR 4.8.1.1.2.a.2 within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> if it cannot be determined that the two remaining operable EDGs are not inoperable due to common cause failure.
When both an offsite circuit and an EDG are inoperable, the current requirement to test the operable EDGs within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> is an unnecessary challenge to operating personnel and can lessen the focus of operations personnel on the actions needed to restore one of the inoperable AC sources to operable status within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. As noted in GL 84-15 (Reference 4), 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> is reasonable to confirm that the operable EDGs are not affected by the same problem as the inoperable EDG.
3.4 Change to TS 3.8.1.1, Action d Eliminating the TS 3.8.1.1, Action d.1, requirement to start and load the operable EDGs within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> when both offsite circuits are inoperable is consistent with the required actions for NUREG-1431, TS 3.8.1, Condition C. Inoperability of both offsite power sources is not indicative of an increased probability that the EDGs would fail to perform their required safety function. The periodic EDG testing required by SR 4.8.1.1.2 to demonstrate EDG operability provides a high degree of assurance that the EDGs are operable. The proposed change would contribute to a reduction in unnecessary equipment challenges and burden on personnel resources, and potential degradation to the EDGs.
3.5 Change to TS 3.8.1.1, Action e Restructuring TS 3.8.1.1, Action e, removes ambiguity as to the actions that must be taken if the specified requirements are not met, and better aligns the action with the intent of NUREG-1431.
Proposed TS 3.8.1.1 Action e.3 removes an inconsistency regarding restoration of the inoperable EDG within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> from time of initial loss if the extended 14 day AOT of TS 3.8.1.1 Action b.4.a)2 was entered.

4.0 REGULATORY EVALUATION
4.1 Applicable Regulatory Requirements/Criteria The proposed changes have been evaluated to determine whether applicable regulations and requirements continue to be met. PSEG has determined that existing requirements continue to be met and that the proposed changes do not require any exemptions or relief from regulatory requirements. The following current applicable regulations and regulatory requirements were reviewed in making this determination:
10 CFR 50.36(c)(2), Limiting conditions for operation 10 CFR 50.36(c)(2) requires Technical Specifications to include limiting conditions for operation, defined as the lowest functional capability or performance levels of equipment required for safe operation of the facility. When a limiting condition for operation of a nuclear reactor is not met, the licensee shall shut down the reactor or follow any remedial action permitted by the technical specifications until the condition can be met. 10 CFR 50.36, paragraph (c)(2)(ii)(C), Criterion 3, states that a technical specification limiting condition for operation of a nuclear reactor must be established for systems that are part of the primary success path and which functions or actuates to mitigate a design basis accident or transient that either assumes the failure of or presents a challenge to the integrity of a fission product barrier. The proposed TS change involves the onsite power system that is required by 10 CFR 50, Appendix A, GDC 17, to provide the independence and redundancy to ensure an available source of power to the systems identified in Criterion 3 above.
10 CFR 50.36(c)(3), Surveillance requirements 10 CFR 50.36(c)(3) requires Technical Specifications to include surveillance requirements, defined as requirements relating to test, calibration, or inspection, to assure that the necessary quality of systems and components is maintained, that facility operation will be within safety limits, and that the limiting conditions for operation will be met. The proposed TS changes alter SR 4.8.1.1.2.a.
The proposed changes are associated with the testing of the operable EDGs when a EDG and/or offsite sources are inoperable. The changes will eliminate unnecessary EDG testing requirements that place needless burden on plant operational personnel and can contribute to potential mechanical degradation of the EDGs. The changes are consistent with NUREG-1431 and are supported in part by GL 93-05 and NUREG 1366. Based on the assessments provided herein, the proposed change to the Salem TS continues to comply with the requirements of 10 CFR 50.36.
10 CFR 50, Appendix A, General Design Criteria for Nuclear Power Plants Salem Units 1 and 2 were designed in accordance with Atomic Energy Commission (AEC) proposed General Design Criteria (GDC), as published in July 1967. The applicable AEC proposed criteria, as documented in Salem UFSAR Section 3.1, were compared to 10 CFR 50, Appendix A GDC. The GDC criteria applicable to this LAR - GDC 17 and GDC 18 - are listed with the correlating AEC proposed criteria below.
GDC Criterion 17 - Electric power systems - An onsite electric power system and an offsite electric power system shall be provided to permit functioning of structures, systems, and components important to safety. The safety function for each system
LR-N25-0053 LAR S22-06 Enclosure 9
(assuming the other system is not functioning) shall be to provide sufficient capacity and capability to assure that (1) specified acceptable fuel design limits and design conditions of the reactor coolant pressure boundary are not exceeded as a result of anticipated operational occurrences and (2) the core is cooled and containment integrity and other vital functions are maintained in the event of postulated accidents.
The onsite electric power supplies, including the batteries, and the onsite electric distribution system, shall have sufficient independence, redundancy, and testability to perform their safety functions assuming a single failure.
Electric power from the transmission network to the onsite electric distribution system shall be supplied by two physically independent circuits (not necessarily on separate rights of way) designed and located so as to minimize to the extent practical the likelihood of their simultaneous failure under operating and postulated accident and environmental conditions. A switchyard common to both circuits is acceptable. Each of these circuits shall be designed to be available in sufficient time following a loss of all onsite alternating current power supplies and the other offsite electric power circuit, to assure that specified acceptable fuel design limits and design conditions of the reactor coolant pressure boundary are not exceeded. One of these circuits shall be designed to be available within a few seconds following a loss-of-coolant accident to assure that core cooling, containment integrity, and other vital safety functions are maintained.
Provisions shall be included to minimize the probability of losing electric power from any of the remaining supplies as a result of, or coincident with, the loss of power generated by the nuclear power unit, the loss of power from the transmission network, or the loss of power from the onsite electric power supplies.
GDC Criterion 18 - Inspection and testing of electric power systems - Electric power systems important to safety shall be designed to permit appropriate periodic inspection and testing of important areas and features, such as wiring, insulation, connections, and switchboards, to assess the continuity of the systems and the condition of their components. The systems shall be designed with a capability to test periodically (1) the operability and functional performance of the components of the systems, such as onsite power sources, relays, switches, and buses, and (2) the operability of the systems as a whole and, under conditions as close to design as practical, the full operation sequence that brings the systems into operation, including operation of applicable portions of the protection system, and the transfer of power among the nuclear power unit, the offsite power system, and the onsite power system.
GDC Criterion 17 is similar to AEC Criteria 24 and 39. GDC Criterion 18 is similar to AEC Criteria 39 and 48.
AEC Criterion 24 - Emergency Power for Protection Systems - In the event of loss of all offsite power, sufficient alternate sources of power shall be provided to permit the required functioning of the protection systems.
AEC Criterion 39 - Emergency Power for Engineered safety Features - Alternate power systems shall be provided and designed with adequate independence, redundancy, capacity, and testability to permit the functioning required of the engineered safety features. As a minimum, the onsite power system and the offsite power system shall each, independently, provide this capacity assuming a failure of a single active component in each power system.
LR-N25-0053 LAR S22-06 Enclosure 10 AEC Criterion 48 - Testing of Operational Sequence of Emergency Core Cooling Systems - A capability shall be provided to test under conditions as close to design as practical, the full operational sequence that would bring the Emergency Core Cooling Systems in to action, including the transfer to alternate power source.
Following implementation of the proposed change, Salem Units 1 and 2 will remain in compliance with AEC Criteria 24, 39, and 48.
4.2 Precedent Removing the requirement to perform the one-hour load run test for the remaining operable EDGs when one EDG is inoperable is consistent with the improved standard TS (e.g.,
NUREG-1431 (Reference 1) and NUREG-1433 (Reference 5)). The NRC approved similar changes for the Hope Creek Generating Station (Reference 6) and the Limerick Generating Station, Unit 1 (Reference 7).
Removing the requirement to test the operable EDGs within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> when one offsite circuit and one EDG are inoperable is consistent with NUREG-1431. The NRC approved a similar change for the Shearon Harris Nuclear Plant (Reference 8).
Removing the requirement to test the EDGs when two offsite circuits are inoperable is consistent with NUREG-1431 and NUREG-1433. The NRC approved similar changes for the Shearon Harris Nuclear Plant (Reference 8), St. Lucie Plant (Reference 9) and the Limerick Generating Station (Reference 10).
Salem Units 1 and 2 are four-loop Westinghouse-designed pressurized water reactors. There are distinct differences between Salem and the other power plants cited above. However, requirements for EDG testing are universally applied across nuclear power plants with installed safety-related EDGs. Therefore, these previous approvals are applicable to Salem.
4.3 No Significant Hazards Consideration In accordance with 10 CFR 50.90, PSEG Nuclear LLC (PSEG) requests an amendment to the renewed Facility Operating License Nos. DPR-70 and DPR-75 for Salem Generating Station, Unit 1 and Unit 2 (Salem). The proposed changes revise Salem Technical Specification (TS) 3/4.8.1.1 to modify the required actions for testing operable emergency diesel generators (EDGs) when EDGs or offsite circuits are inoperable. To accommodate this proposed change, the current TS Surveillance Requirement (SR) combining the EDG starting test and the load-run test is split into two separate SRs. In addition, in the condition of multiple AC sources being inoperable, the proposed changes align the restoration time for a remaining inoperable EDG consistent with the time of entry (when that specific EDG initially became inoperable) and the established Allowed Outage Time.
PSEG has evaluated whether a significant hazards consideration is involved with the proposed amendment(s) by focusing on the three standards set forth in 10 CFR 50.92, "Issuance of amendment," as discussed below:
- 1.
Does the proposed amendment involve a significant increase in the probability or consequences of an accident previously evaluated?
Response: No.
LR-N25-0053 LAR S22-06 Enclosure 11 The proposed changes revise the Salem TS to better align with the standard TS in NUREG-1431 for inoperable EDGs and offsite circuits. The proposed changes do not affect the operational limits or the physical design of the EDGs or offsite circuits.
The EDGs and offsite circuits are not accident initiators. The proposed changes will minimize unnecessary testing that can result in additional degradation and will reduce the burden on plant operating personnel while continuing to ensure EDG and offsite circuit reliability.
Since the proposed changes do not affect any accident initiator and since the EDGs and offsite circuits will remain capable of performing their design function, the proposed change does not involve a significant increase in the probability or radiological consequences of an accident previously evaluated.
Therefore, it is concluded that this change does not involve a significant increase in the probability or consequences of an accident previously evaluated.
- 2.
Does the proposed amendment create the possibility of a new or different kind of accident from any accident previously evaluated?
Response: No.
The proposed changes revise the Salem TS to better align with the standard TS in NUREG-1431 for inoperable EDGs and offsite circuits. The proposed changes do not affect the design function or operation of the EDGs or offsite circuits. The EDGs and offsite circuits will remain capable of performing their design function. No new failure mechanisms, malfunctions, or accident initiators are being introduced by the proposed changes.
Therefore, it is concluded that this change does not create the possibility of a new or different kind of accident from any accident previously evaluated.
- 3.
Does the proposed amendment involve a significant reduction in a margin of safety?
Response: No.
The proposed changes revise the Salem TS to better align with the standard TS in NUREG-1431 for inoperable EDGs and offsite circuits. The proposed changes do not exceed or alter a design basis or safety limit. The EDGs and offsite circuits will remain capable of performing their design function. Unnecessary testing that can result in increased degradation of the EDGs will be minimized by the proposed changes.
Therefore, the proposed change does not involve a significant reduction in a margin of safety.
4.4 Conclusions In conclusion, based on the considerations discussed above, (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commissions regulations,
LR-N25-0053 LAR S22-06 Enclosure 12 and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.
5.0 ENVIRONMENTAL CONSIDERATION
A review has determined that the proposed amendment would change a requirement with respect to installation or use of a facility component located within the restricted area, as defined in 10 CFR 20, or would change an inspection or surveillance requirement. However, the proposed amendment does not involve (i) a significant hazards consideration, (ii) a significant change in the types or a significant increase in the amounts of any effluents that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure. Accordingly, the proposed amendment meets the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(c)(9). Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed amendment.
