SUBJECT:
REQUEST FOR ADDITIONAL INFORMATION, RESIDUAL HEAT REMOVAL PUMP TESTING, BULLETIN 88-04, POTENTIAL SAFETY-RELATED PUMP LOSS, SALE" NUCLEAR GENERATING STATION, UNIT 1 (TAC NO. M87200)
By letter dated August 2, 1993, Public Service Electric and Gas Company (PSE&G) informed the NRC staff that system modifications would not be undertaken to preclude the condition of a strong pump overcoming the discharge head of a weak pump, thus causing the weak pump to be operated in a no flow (deadheaded) condition.
In lieu of system modifications, PSE&G proposed to use residual heat removal (RHR) pump testing to determine the operability of the pumps.
In reviewing the letter, the staff raised some questions which were the subject of a telephone call between your staff and the NRC staff on October 1, 1993.
In order for the staff to complete their review of your request, the following information is requested:
- 1.
In the August 2; 1993 letter, the acceptance criteria is listed as 300 gpm per pump with the RHR pumps operating in parallel. This would provide adequate flow for 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> of pump operation. Please provide the basis for the 300 gpm limit and the 3-hour limit.
- 2.
In the August 2, 1993 letter, the statement that "The Technical Specification surveillance program in accordance with 4.0.5-P testing will be used to monitor for strong-weak pump interaction." is included.
However, the 4.0.5-P program'does not require operating the pumps in parallel. Please provide a summary of the 4.0.5-P program and the enhancements to be added for testing the RHR pumps at Salem 1.
Include how trending will be done, when corrective action will be taken, and any administrative controls that will be added.
- 3.
Identify the accident scenarios where the strong-weak pump interactions may be a concern.
Does the proposed testing simulate the conditions that would be expected during the identified accident scenarios? In the emergency operating procedures (EOP) for the identified accident scenarios, how are the operators alerted to the possibility of a strong-weak pump interaction taking place?
- 4.
In a letter dated August 31, 1990, PSE&G proposed to use differential pressure between the RHR pumps to determine if deadheading was occurring
