SUBJECT:
SAFETY EVALUATION OF THE DIABLO CANYON UNITS 1 AND 2 TEN-YEAR INSERVICE INSPECTION (ISI)
PROGRAM PLAN (TAC NOS.
62155 AND 60656)
The purpose of this letter is to forward the NRC staff's safety evaluation reports (SERs) addressing the First Ten-Year Interval ISI Program Plan for the Diablo Canyon Nuclear Power Plant, Units 1 and 2.
The SERs cover the ISI Program Plan through Revision 5 for Unit 1 and Revision 2 for Unit 2, which you submitted by letter dated January 26, 1987.
The NRC staff, with technical assistance from the Idaho National Engineering Laboratory (INEL),
has reviewed and evaluated the above plans and the additional related information that you have submitted.
The Technical Evaluation Reports (TERs) prepared by INEL are also attached.
Based on the information that you have provided, the NRC staff agrees with the conclusions and recommendations presented in the INEL TERs.
lie have determined that certain Section XI Code requirements are impractical to perform at Diablo Canyon.
Therefore, we are granting relief from these requirements.
- However, we are not granting Relief Requests 2A, 2B, or 3 concerning hydrostatic tests of Class 2 and 3 cooling water
- systems, because the supporting information provided was insufficient to support a finding that the Code requirements are impractical.
A summary of the bases for granting or denying each of your relief requests is included in the attached
In summary, the staff has concluded that the Diablo Canyon ISI programs, with the additional information provided and the reliefs granted, are in compliance with the requirements of (1) the 1977 Edition through Summer 1978 Addenda of Section XI of the ASME Boiler and Pressure Vessel
- Code, (2) 10 CFR 50.55a, and (3) commitments made prior to issuance of the facility operating licenses.
Based on this, we find the ISI programs acceptable.
