g wasmuoton. o c. 4o546 December 5,1969 Peter A. Morrio, Director Division of Benetor Licensing GLI1ERAL QUESTIQ18 ARISD10 }TtCH ' DIE MulTICFILO SUUCUNI7' FEE MEETD10 At the Monticello Subcommittee Meeting on November 29 a number of items were raised by membero of the Subcommittee that bear on our N
Monticello review as well as other safety reviews.
I anticipate that nany of these questions will have to be faced at the December v
'g ACRS Meeting.
The more important of these problems are the-followingt 1
Both Dr. Okrent and Mr. Etherington requested that we prepare a supplemental report on the Monticello loose endo co we don't have tc " report orally" to the Committee.
From their reaction I feel that we should no longer promise to report orally on loose.end items, and in the future we should plan preparation of cupplemental reports where required.
2 Dr. Okrent requested our position on pipe whip, especially for new plants such as Shoreham and Duane Arnold. He appreciates that for planto already constructed we may accept a compromise position, but for construction permit reviews he would like our specific recommendations and conclusions.
This matter has been raised by Dr. Okrent previously and I have asked Bob Tedesco to prepare a proposed position on pipe whip.
3.
Dr. Okrent raised a number of questions on in-service inspection, using su h areas as the pressure vessel, pipe whipping, and systematic failures as examples.
His questions relate to how ve decide what's enough in-service inspection in general and what are we looking for so we can decide what's enou6h?
