SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 203 TO FACILITY OPERATING LICENSE NO. DPR-46 NEBRASKA PUBLIC POWER DISTRICT COOPER NUCLEAR STATION DOCKET NO. 50-298
1.0 INTRODUCTION
By application dated August 25, 2003 (ML032450233), Nebraska Public Power District (the licensee), requested changes to the Technical Specifications (TS) for Cooper Nuclear Station.
The proposed changes would revise TS 3.5.1 to incorporate TS Task Force (TSTF) Standard TS Change Traveler, TSTF-318, Revise 3.5.1 for one LPCI [low pressure coolant injection]
pump inoperable in each of two ECCS [emergency core cooling system] divisions.
The current TS 3.5.1 Condition A provides for a seven-day Limiting Condition for Operation (LCO) for one inoperable LPCI subsystem. The proposed amendment would modify TS LCO requirement 3.5.1 for Condition A to allow one LPCI pump inoperable in both LPCI subsystems for a period of seven days. The current TS actions require entry into shutdown LCO 3.0.3 for this condition. The proposed change will also revise Conditions D, F, and H to be consistent with and reflect the change to Condition A. The proposed addition to Condition A with one LPCI pump inoperable in both subsystems, reflects an enhanced reliability of at least one LPCI pump being available for post-loss of coolant accident (LOCA) injection. Additionally, during an event that does not impact LPCI availability and requires LPCI injection, one pump in each LPCI subsystem provides more injection flow than two pumps in a single subsystem.
2.0 REGULATORY EVALUATION
The staff finds that the licensee in Section 5.2 of its submittal identified the applicable regulatory requirements and guidance. The regulatory requirements and guidance on which the staff based its acceptance are TSTF-318 and NUREG-1433, Standard Technical Specifications General Electric Plants, BWR [Boiling Water Reactor]/4," Volume 1, Revision 2, June 2001 (ML011090341).
The proposed change is consistent with the NRC-approved TSTF-318. In addition, the proposed change is consistent with NUREG-1433. The TS Bases for TS 3.5.1 will be revised to provide supporting and clarifying information for the condition of one LPCI pump in both LPCI subsystems being inoperable at the same time for a period of seven days.
3.0 TECHNICAL EVALUATION
The staff has reviewed the licensees regulatory and technical analyses in support of its proposed license amendment which are described in Sections 5 and 4, respectively, of the licensees submittal.
The pre-TSTF-318, TS 3.5.1 LCO Actions required actions to be taken when two LPCI pumps in a given LPCI subsystem were not operable, and required entry into shutdown LCO 3.0.3 for a condition of one LPCI pump in each subsystem inoperable. NRC-approved TSTF-318 revised TS 3.5.1 by adding to TS 3.5.1 LCO Actions, Condition A, a provision for the inoperability of one LPCI pump in both LPCI subsystems during MODES 1, 2, and 3 for seven days. Therefore, the proposed change will allow two inoperable LPCI pumps (i.e., one in each subsystem or two from one subsystem) for seven days in MODES 1, 2, and 3.
The standard BWR/4 residual heat removal (RHR) configuration consists of two LPCI pumps in each of the two LPCI (ECCS injection mode) subsystems, for a total of four LPCI pumps.
Typically, one subsystem consists of pumps A and B and the second subsystem consists of pumps C and D. Pumps A and C are powered from Electrical Division I and pumps B and D are powered from Electrical Division II. The pre-TSTF-318 TS 3.5.1 Condition A allowed one low pressure ECCS injection/spray subsystem (i.e., one or both LPCI pumps in one subsystem) to be inoperable for seven days during MODES 1, 2, and 3. The allowed two inoperable LPCI pumps from one subsystem were from two different electrical divisions. However, despite the power supply diversities, the currently acceptable configuration is not single failure proof. A single failure of the remaining subsystems injection valve (i.e., electrical or mechanical failure) would result in unavailability of all four LPCI pumps.
TSTF-318 added a new entry into TS 3.5.1 Condition A which would also allow two inoperable LPCI pumps (one in each subsystem) for seven days. The staff considered it acceptable to have two LPCI pumps from the two subsystems out-of-service because this configuration represents a level of risk equal to or less than that of the currently approved configurations by:
1.
Providing adequate injection to either loop (pumps not injecting into the same header will actually provide more flow), and 2.
Not being vulnerable to single failure of the injection valve, and if pumps are from different emergency power divisions (not required but desirable), not being vulnerable to a single emergency diesel generator failure.
The ECCS is designed to limit fuel clad temperatures over the complete spectrum of possible break sizes in the reactor coolant pressure boundary including the design basis break. The LPCI subsystems provide protection to the core in the case of a large break in the reactor coolant pressure boundary when reactor water level cannot be maintained and the reactor vessel rapidly depressurizes. Protection extends to a small break in which High Pressure Coolant Injection is unable to maintain the reactor water level and the Automatic Depressurization System has operated to lower reactor vessel pressure.
The proposed addition to Condition A reflects an more reliable configuration of at least one LPCI pump being available for post-LOCA injection. With one subsystem inoperable, the LOCA can eliminate the availability of the remaining subsystem for injection, while a LOCA during operations with only one LPCI pump in each ECCS division will only remove the availability of one of the two remaining LPCI pumps. Additionally, during an event that does not impact LPCI availability and requires LPCI injection, one pump in each LPCI subsystem provides 400 gallons per minute more injection flow than two pumps in a single subsystem.
Thus, allowing one LPCI pump to be inoperable in both subsystems for a period of seven days will not affect the ability of the LPCI subsystem components to perform their designed function.
This TS change represents a more reliable LPCI configuration than allowed by the current TS, and therefore, the same seven-day Completion Time is justified.
License amendments to revise TS 3.5.1, for one LPCI pump inoperable in each of the two ECCS divisions, have been approved by the NRC staff for Browns Ferry, Susquehanna, and Peach Bottom.
The staff has reviewed the licensees regulatory and technical analyses in support of its proposed license amendment. The proposed change: (1) provides adequate injection to either loop, with pumps not injecting into the same header providing more flow, and (2) does not cause vulnerability to single failure of the injection valve, and if pumps are from different emergency power divisions (not required but desirable), does not cause vulnerability to a single emergency diesel generator failure. The proposed revision to Conditions D, F, and H are consistent with and reflect the change to Condition A, and are consistent with TSTF-318.
Based on the above, the staff finds that the licensees proposed amendment is acceptable.
4.0 STATE CONSULTATION
In accordance with the Commission's regulations, the Nebraska State official was notified of the proposed issuance of the amendment. The State official had no comments.
5.0 ENVIRONMENTAL CONSIDERATION
The amendment changes a requirement with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20. The NRC staff has determined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendment involves no significant hazards consideration, and there has been no public comment on such finding published October 14, 2003, (68 FR 59218). Accordingly, the amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9). Pursuant to 10 CFR 51.22(b) no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendment.
6.0 CONCLUSION
The Commission has concluded, based on the considerations discussed above, that: (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, 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.
