UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20555 September 12, 1989 Docket No.:
50-206 Mr. Harold B. Ray Vice President Southern California Edison Company Irvine Operations Center 23 Parker Irvine, California 92718
Dear Mr. Ray:
SUBJECT:
AMENDMENT APPLICATION 162 REGARDING CONTAINMENT SPRAY ACTUATION INSTRUMENTATION FOR SAN ONOFRE NUCLEAR GENERATING STATION, UNIT 1 (TAC NO. 71807)
In reviewing your Amendment Application 162 dated December 29, 1988, regarding containment spray actuation instrumentation, we have determined that the following additional information is needed to continue our review. In order to maintain our review schedule, your response is requested within 30 days of your receipt of this letter. This matter was discussed in a telephone conversation between Messrs. J. Tatum (NRC) and R. Ornelas (SCE) on August 28, 1989.
Request for Additional Information
- 1. Your proposed Action 32 for Containment Pressure -
(High-High) in Table 3.5.11-1 is not consistent with Action 9 for Containment Pressure - High in Table 3.5.5-1 of your existing Technical Specifications. Recognizing that the transmitters used for sensing the Containment Pressure (High-High) condition are shared between the two safety trains, your proposed Action 32 may not be appropriate. Please provide your basis for the proposed action statement, or provide an alternate action statement with accompanying basis. Your basis should also be reflected in the Basis section of the Technical Specifications.
- 2. In Table 3.5.11-2 you propose a Trip Setpoint of less than or equal to 10 psig and an allowable value of 10 psig for Containment Pressure (High-High). You have not provided any margin between the allowable value and the Trip Setpoint, which is not consistent with the approach that was used for Containment Pressure - High in Table 3.5.5-2 of your existing Technical Specifications. Please provide your basis for the allowable value and the Trip Setpoint that you have selected for Contain ment Pressure - (High-High), or provide alternate values with accompanying basis. Your basis should also be reflected in the Basis section of the Technical Specifications.
- 3. Your proposed change to the Technical Specifications will require a change to the Technical Specification Table of Contents. Please provide the appropriate replacement pages.
