MEMORANDUM FOR:
File FROM:
Lawrence J. Strickler, Investigator, OIA
SUBJECT:
INVESTIGATION - MICHELSON RE ORT During the afternoon of July 6,1979, Scott Newberry was interviewed in his office in the Phillips Building by OIA Investigators David Gamble and Lawrence J. Strickler.
'3ewberry was advised that the purpose of the interview was to reconstruct e.cnts and levels of review regarding the analysis of Carlyle Michelson's report, " Decay Heat Removal During A Very Small Break LOCA For A B&W 205 - Fuel-Assembly PWR."
flewberry advised that until July 1,1979, when he was reassigned to a.
r-special TMI related study group, he was a Reactor Engineer with the.
Reactor Systems Branch, Division of Systems Safety, Office of Nuclear Reactor Regulation and that he had maintained that title and function since prior to January 1978.
Newberry said that prior to TMI he had not read, seen, or even heard of the "Michelson Report." He said that while at TMI, after the March 28, 1979 accident, he heard of the report but has not seen or read it.
Newberry confirmed that in January 1978 he received a copy of that note dated January 10, 1978 and addressed to "RSB Members," which was prepared by Section Leader Sanford Israel and signed by Branch Chief Thomas Novak, and entitled, " LOOP SEALS IN PRESSURIZER SURGE LINE." He said that the first opportunity he had to take action on the recommendation in Israel's note was in regard to the OL (Operating License) review of Midland which began in about the same time frame in which he received the note.
He said that he cannot recall having prepared any questions based on the recommendation in Israel's note but that Midland is still under review and that the process of asking questions is still continuing.
Newberry said that he does not know what specifically caused Israel to write the January 1978 note and confirmed that there was no staff discussion of the note subsequent to its receipt by the> staff.
Newberry explained that as far as he personally knows, there is no formal process for bringing those concerns which arise during either a CP (Construction Permit) review or an OL review, to the attention of perscnnel responsible for operating reactors which are based on the same or similar design.
