$orrelf uNasJacbuseth 0/854 OFFICE OF THE PRESIDENT March 16, 1979 Docket No. 50-223 United States Nuclear Regulatory Commission Attn:
Mr. Robert Purple Operating Reactors Branch #1 Division of Reactor Licensing Washington, D.C.
20555 Gentlemen:
The Universit-of Lowell requests that the Univer. city of Lowell Reactor License No. R-125 be amended as follows:
1.
Change Section 4.4.3, Technical Specifications, Appendix A to License R-125, to read:
4.4 Containment Building Specification 3.
An integrated Icakage rate of the containment building, as is, shall be performed at a pressure of at least 0.5 psig at intervals of 2_4 months (1 4 mo.) to varify leakage rate of less than 10% of the building air volume / day at 2 psig.
This reduction in frequency from 12 to 24 months would bring the University of Lowell's Reactor Containment test frequency into line with the suggested freauency of ANSI N45.4 - 1972.
Leakage rates measured each of the last four years have been less than 25% of that specified and show no signs of increasing.
- incerely, J
Subscribea and sworn to before me John B. Duff this 21s cf Merch, 1979.
