Waterford 3 SBS Docket No. 50-382 License No. NPF-38 Technicar Specification Change Rcquvat NPF-38-122 Additional Information Gentlemen:
Per your request the following additional information is being provided concerning the subject Technical Specification Change Request.
In accordance with Generic Letter 91-08 " Removal'of Component Lists from Technical Specifications" TS 4.8.4.1.a.2 was-revised to include a note from table 3.8.1 (note II.6'page 3/4 8-51b) which constitutes an exception to the TS requirement.
TS 4.8.4.1.a.2 concerns the functional testing of lower, voltage circuit breakers and states that the test "shall-consist of injecting a current in excess of the breaker's nominal setpoint and measuring tne response-time."' This test method is not applicable for the General Electric low voltage (480-volt) power circuit breakers as these breakers are equipped with external solid-state overcurrent trip devices.
The staff questioned if
" Channel Calibration" could be used to describe the~ test performed on: these breakers.
The answer is n).
These breakers are' subjected to a functional test in accordance with General Electric's recommendations rather than a channel calibration.
In responding to your question it was observed where the existing TS note 11s misicading in'that it refers-to testing'in accordance with the " vendor's calibration procedures".
Testing'of these specific breakers per TS-4.8.4.1.a.2 is actually performed in 4
accordance with Waterford 3 Maintenance Electrical Procedure ME-003-314, " General-Electric ECS and SST Programmers" which is t
based on'the manufacturers' recommendations.
Therefore, the asterisk note on our proposed TS change (page 3/4:8-17)_should be clearified by removing the reference to " vendor's calibration procedures" and inserting " manufacturer's recommendations".
