20545 Re: Oconee Nuclear Station Units 1 and 2 Docket Nos. 50-269 and -270
Dear Mr. Giambusso:
My letter of March 8, 1974 requested certain changes to Oconee Technical Specification 3.5.2.
In that letter, it was stated that for the locked rotor transient the DNBR was not noticeably affected by the higher values of the revised specific heat curve for uranium dioxide fuel.
During review of this requested change, members of your staff have asked if the 1.4 second flow measurement time constant (reported in Supplement 17 to the Oconee FSAR) was included in the locked rotor transient analysis.
Please be advised that the 1.4 second time constant was included in the analysis, and therefore, the conclusions reported in my March 8,1974 submittal are valid for both the revised specific heat curve and the flow measurement time constant of 1.4 seconds reported in Supplement 17.
Ve truly yours4' d. s.w ka,.
