Additional Information Regarding Generic Letter 83-28 Item 1.1
Dear Sir:
In our original response to Generic Letter 83-28 [ Reference (b)], New Hampshire Yankee committed to address those items identified under Item 1.1,
" Post Trip Review" (Program Description and Procedure), with a post trip safety assessment procedure. Our initial commitment was to implement the procedure covering Item 1.1, three months prior to core load.
Seabrook Station has established a " Post Trip Review" procedure (Procedure No. OS1000.08) which establishes the requirements for performing formal post trip reviews for all reactor trip and safety injection events, and the criterion which must be met prior to starting up af ter a trip.
As it was recently requested by members of your staf f, please find enclosed a copy of Seabrook Station's " Post Trip Review" procedure. As discussed in a previous response to Staff concerns [See Reference (c)}, the data and information used during a post trip review will be retained in hard copy for the duration of the Seabrook Station operating license per the requirements of Technical Specification 6.9.3(e).
Additionally, your Staff requested clarification of the post trip review process regarding evaluations with respect to the plant Technical Specifications and FSAR. Our post trip review information will be analyzed for protection system response and overall plant behavior, and this will be comphred with expected plant response (s) as described in the Technical Specifications and/or FSAR.
