Dear Mr. Lear:
Re:
Turkey Point Units 3
a 4
Docket Nos.
50-250 and 50-251 Boron Dilution As a result of your letter of September 19,
- 1977, we have eval-uated Turkey Point Units 3
6 4 to determine the potential for boron dilution occurrences.
The evaluation has shown that no dilution sources other than those previously analyzed have flow paths into the reactor coolant system.
Neither of these units has a sodium hydroxide system.
Therefore, based on our review of this issue, the only dilution occurrences that are credible at Turkey Point Units 3
6 4 are those associated with the chemical and volume control system as addressed in Section 14.1.5 of the FSAR.
Very truly yours, Robert E. Uhrig Vice President REU/MAS/RJA/lah cc:
