FLORIDA POWER CORPORATION CRYSTAL RIVER UNIT 3 DOCKET NO. 30-302/ LICENSE NO. DPR-72 REQUEST NO.111, REVISION O LICENSE DCCUMENT INVOLVED:
Technical Specifications (Appendix A)
PORTION:
Table 3.3-1; Reactor Protection System Instrumentation Table 4.3-1; Reactor Protection System Instrumentation Surveillance Requirements REGULATORY BASIS: 10 CFR 50.90 DESCRIPTION OF REQUEST:
Add the following parenthetical note to Table 3.3-1 and Table 4.3-1, item 11: "(including silicon controlled rectifiers)".
l REASON FOR REQUEST:
l Generic letter 83-25, " Required Actions Based on Generic Implications 01 $alem ATWS t
Events", item 4.4, requests that silicon controlled rectifiers be included in the appropriate serveillance and test sections of the Technical Specifications. This proposed change is in l
response to this request.
1 l
Determination of silicon controlled rectifier (SCR) operability is accomplished using guidelines developed by Babcock and Wilcox. As stated in the guidelines:
l SCR testing is basically divided into two parts; verifying that the SCR trip relays have in fact tripped (deenergized) in response to an RPS trip command, and verifying that the SCR's themselves have tripped (deenergized).
l EVALUATION OF REQUEST:
l As there was no hardware change and as this proposed change simply highlights an action Florida Power Corporation is already performing there is no affect on any safety margin or safety analys's.
l l
REFERENCE:
Generic Letter 83-28 Letter to E. M. Howard, FPC from Babcock and Wilcox; "SCR Test Proced.re - Oconee Series Plants"; dated September 9,1983.
