Docket Nos.
50-250 S 50-251 Pressurized Thermal Shock Flux Reduction Pro ram
Dear Mr. Varga:
Your letter dated November 17, 1983 requested a schedule for providing integral neutron source data to allow evaluation of FPL's flux reduction.
This data will be supplied on the following schedule:
Unit 4 Cycle 9
Unit 3 Cycle 9
Unit 4 Cycle 10 March 1,
1984 April 1,
1984 August 1, 1984 Regarding your letter, we would like to clarify that the expected flux reduction factor of 3.3 will be achieved by the use of a combination of highly burned fuel and borosilicate glass burnable absorbers on the core flats of Turkey Point Unit 3 Cycle 9 ~
The use of Optimized Fuel Assembly and Wet Annular Burnable Absorber designs is for the purpose of nuclear fuel economy and is unrelated to the flux reduction.
Also, the near term flux reduction factor of 3.3 is anticipated to extend our reaching the screening criteria to the year 2004.
The expected long term flux reduction factor of about 4 in subsequent cycle core designs will extend this time to 2007.
Very truly yours, J.
W. Williams, Jr.
