CrystalRiver, FL 34428-6708 RE: Carifications to APTECH's Calculation AFS-('AS4L1, " Deterministic Operational Assessment for Free-Span Outside Diameter Stress Corrosion Cracking Degradation at Crystal River, Unit 3" (AFTECH Pmject AES 98103543-10)

Dear Mr. Sexton:

Per your request, the following clarifications are provided conceming AFTF.CR'n Calenlation AES-C-35431 transmitted to you under separate cover dated December 23,1998.

1. The calculation used the terminology of EFPY for the term of operation evaluated in the calculation. 'Ihe intended definfrion of EFPY, in the calculation,is time at or above 500*F.
2. The bases for the calculation are as follows:

- Best estimate growth rate from field data

- Probability of detection based on resolution analyst calls that included all system error

- Extreme value statistics for deterruinins limiting flaw depth at end-of-cycle

- 95/95 confidence limits on burst pressure

- Rigorous Monte Carlo statistical simulation Please contact meif additionalinformation is required. I may be reachedin AITECH's Sunnyvale, California office at 408/745-7000 or paged at 888/580-0053.

Sinecrcly,
