i BACKGROUND Franklin Research Center (FRC) of Philadelphia, Pa. is providing assis-tance to the U.S. Nuclear Regulatory Commission (NRC) for the equipment environmental qualification (EEQ) review of operating reactors. FRC will perform an EEQ review of the Licensee's 90-day response to outstanding issues from the NRC Equipment Environmental Qualification Safety Evaluation Report (S ER) and the installed TMI Action Plan equipmen't. The review will be limited
~
'to safety-related equipment potentially exposed to a harsh environment. The results will be presented in the form of a technical evaluation report for each plant.
This request for additional information (RAI) is the resul?. of an evaluation of the information provided by letters dated September 14, 1981 (1), February 1, 1982 (2), and March 5, 1981 [3).*
FRC previously requested TMI Action Plan information by telephone memoranda dated July 27,1981 and Septemmer 14, 1981 (4,5].
In response to Reference 4, Georgia Power Company transmitted the following information wnich was received at FRC on August 14, 1981 [6):
1.
Southwest Research Institute letters to Hays Republic Div. Milton Roy Company, dated 29 May 1980, 19 November 1979, 21 February 1980, and 26 February 1980, concerning SwRI Project No.
~
11-5453-013,
" Irradiation of Instrumentation."
