Conway:
SUBJECT:
TURKEY POINT UNITS 3 AND 4 REACTOR VESSEL FRACTURE TOUGHNESS (TAC NOS.
68249 AND 55042)
The purpose of this letter is to transmit our review of two reports submitted by Florida Power and Light Company (FP8 L).
These reports were intended to demonstrate by analysl.s the existence of adequate safety margins in the Turkey Point Units 3 and 4 reactor vessels when the Charpy upper-shelf energy is below the 50 ft-lb requirement in Appendix G of 10 CFR 50.
By letters dated May 3, 1984 and March 25, 1986, FP8L submitted for NRC.'s review a, fracture toughness analysis of the beltline welds for the Turkey Point reactor vessels.
In our Safety Evaluation (enclosed) we have identified the need for additional analysis and data acquisition.
Until this information is provided, we cannot complete our review of the reports.
Me request that within one year of the date of this letter, FP8IL provide a revised analysis incorporating the information requested and a plan for data acquisition.
The analysis should include an estimate of the Charpy upper-shelf energy at both the next refueling outage following the submittal date of the report and at expiration of the Turkey Point Units 3 and 4 licenses.
The Charpy upper-shelf energy estimates for the beltline weld should be based on the plant's anticipated future fuel management plan and extrapolation of the
,surveillance data from the Turkey Point Integrated Surveillance Program using the method recommended in Regulatory Guide 1.99, Rev. 2.
Me also recommend that FP8L contact the ASME Code Section XI Committee (Morking Group on Flaw Evaluation) to determine the status of the Committee's development of recommended safety margins and any impact they would have on Turkey Point if approved for use by the NRC.
