Dear Mr. O'eary:

DOCKET NOS.
50>>250 AND 50-251 REQUEST FOR TECHNICAL SPECIFICATION CHANGE FUEL RESIDENCE TIME The following information is submitted to supplement my letter of April 5, 1974, to Mr. D. J. Skovolt on this subject.
The calculational methods used in the report, "Fuel Densification Turkey Point Plant Units 3 and 4
>> Low Pressure Analysis",
ÃCAP-8136, dated June, 1973", were used to determine the requested changes in fuel residence time using inputs of actual operating times at full and reduced pressure.
The safety evaluation for this proposed change considered minimum DNB ratio, stored energy, and time-dependent creep collapse of fuel cladding and it is concluded that this change has no effect on safety limits and does not in-volve a significant hazards consideration.
It should also be noted that the proposed residence time for Unit No.
4 is an upper limit but not the limiting condition.
The fuel will be exposed to its design life prior,to the expected clad col-lapse time.
Very truly yours,
)4A.~
