EICSB/DPA Review Status Incomplete By letter dated May 23, 1986, TVA submitted proposed Technical Specification changes for the Sequoyah Nuclear Station, Units 1 and 2 in response to Generic Letters 83-28 and 85-09.
Other proposed Technical Specification changes are also included. The enclosed Safety Evaluation Report pertains only to the Generic Letter 83-28 and 85-09 items. The other changes are to be reviewed under separate TAC numbers.
EICSB finds the proposed Technical Specification changes pertaining to Generic Letters 83-28 and 85-09 acceptable except for the following:
1.
For the Reactor Trip System Instrumentation, Table 3.3-1, Modes 3*,4*,5*
should be separated from Modes 1 and 2 for Functional Units 20 (Reactor Trip Breakers) and 21 (Automatic Trip Logic), and an action statement added, similar to Action 13 of Generic Letter 85-09, for Modes 3*,4* and 5* (asterisk means with the reactor trip system breakers in the closed position, the control rod drive system capable of rod withdrawal, and fuel in the reactor vessel).
2.
Table Notation (9) of Table 4.3-1 should be expanded to test the operability of the Bypass Breaker trip circuits.
