The.subject of the meeting was the CP,CO a*1J1endment request dated *July 2, 1979 and an NRC response dated August*21, 1979.

The August 21, 1979

  • letter found the July 2, 1979 r~quest unacceptable for three reasons:

~. one related to uncertainties in end-of-life vessel fluence, the* second

  • related to. the un1rra~fa_te~ v~lue of RTNDT, and the third related tq the increase 1n RTNDT with r~d.ia~Jon-dam~ge *., It was agreed that disoussion.

of end-of-life fluence woula be deferred for about one week pending..

additional.calculations to be perfor111e~ ~Y the CPCO consultant. **The NRC staff provided additional backgrQµnd for the *positions stated in

Based on the-meeting an understand1ng wa~ reached that CPCO would submit revised pressure. temperature operating 11mits based on th.e August 21,

OF SEPTEMBER.26_, 1979.MEETING WITH.CONSUMERS POWER COMPANY ON PROPOSED HEATUP AND COOLDOWN CURVES On September 26, 1979, we met with represeritatives of CPCO to discuss*

The subject of the meeting was the CPCO amendment request dated July 2, 1979 and an NRC response dated August 21, 1979.

The August 21, 1979 letter found the July 2, 1979 request unacceptable for three reasons:

one related to uncertainties in end-of-life vessel fluence, the second related to the unirradiated value of RTNDT' and the third related to the increase in RTNtiT with radiation damage.

It was agreed that discussion of end-of-life fluence would be deferred for about one week pending additional calculations to be performed by the CPCO consultant. The NRC staff provided additional background for the positions stated in items (2) and (3) in the August 21, 1979 letter. *The CPCO represen-tatives provided additional data with respect to vess~l welds (attached).

Based on the meeting an understanding was reached that CPCO would submit revised pressure temperature operating limits based on the August 21, 1979 NRC letter subsequent to verifying the end-of-life fluence.
