1983 Docket No.:

50-410 APPLICANT:

Niagara Mohawk Power Corporation (NMPC)

FACILITY:

Nine Mile Point Unit 2

SUMMARY

OF MEETING WITH NMPC TO DISCUSS ADMINISTRATIVE MATTERS RELATED TO NINE MILE POINT UNIT 2 (NMP-2)

On November 22, 1983, the NRC staff met with representatives from NMPC to discuss administrative matters related to NMP-2.

Among the subjects discussed were the bases for a number of requests for additional information that were requested for NMP-2.

Specific examples in Seismology (determination of SSE to be used),

Hydrology (use of standards to determine PMP),

and Structural Engineering (information needed when codes other than those in the SRP are used) were discussed.

The applicant noted that a significant amount of work had been done in the area of seismology that was not accounted for in the requests for information.

The NRC staff stated that detailed evaluations are not performed in the requests for information but are done later in the Safety Evaluation Report (SER).

The applicant stated they considered it sufficient to use Hydrometeorology Report No.

33 for determination of Probable Maximum Precipitation (PMP) as it is specifically mentioned in the Standard Review Plan (SRP)

NUREG-0800.

The NRC staff responded that although this standard is mentioned, the SRP also states that the latest methodology should be used when appropriate in determining PMP.

Hydrometeorology reports 51 and 53 contain updated information and more advanced methodology to determine the PMP.

These later reports are being used for other plants.

The staff has evaluated the use of these later reports with respect to the SRP and have determined it is in conformance with the SRP.

For Category I structures, and interior structures of containment which were designed and built to ACI 318 rather than ACI 349 as referenced in the

SRP, the applicant was requested to identify and justify, with respect to safety, all deviations of these structures from the applicable requirements of ACI 349 as amended by the Regulatory Guide 1.142.

The NRC staff will then evaluate these deviations and justifications to assure there is no impact to the safety of this plant as a result of these deviations.

The NRC staff noted that the applicant could make use of the appeal process to take discussions to a higher level whenever agreement could not be reached between the NRC staff and the applicant.

The applicant noted that communications between the NRC staff and the NMPC staff should remain open to provide necessary clarifications expeditiously.

A copy of the attendance list is attached.
