Docket Nos. 50-245 and 50-336 Northeast Nuclear Energy Company ATTN: Mr. Donald C. Switzer President P. O. Box 270 Hartford, Connecticut 06101 Gentlemen:
RE: MILLSTONE NUCLEAR POWER STATION UNITS NOS. 1 AND 2 On November 29, 1976, the Commission published in the Federal Register, (copy enclosed) an amended Section 20.103 of 10 CFR 20, which became effective on December 29, 1976. One effect of this revision is that in order to receive credit for limiting the inhalation of airborne radioactive material, respiratory protective equipment must be used O
as stipulated in Regulatory Guide 8.15.
Another requirement of the
~j amended regulation is that licensees authorized to make allowance for use of respiratory protective equipment prior to December 29, 1976, must bring the use of their respiratory protective equipment into conformance with Regulatory Guide 8.15 by December 29, 1977.
Because the respiratory protective program described in Section 6.12 of your facility Technical Specifications differs from that stipulated in Regulatory Guide 8.15, the effect of this change in the regulations is to require amendment of your Technical Specifications.
In view of the provisions of Section 6.11 of your Technical Specifications, which require conformance with 10 CFR 20, the fact that Section 20.103 no longer requires specific authorization to employ respiratory protective equipment, and the revocation provisions of subsection 6.12.3, we conclude that the necessary amendment to your facility's Technical Specifications can be effected by merely deleting Section 6.12.
Accordingly, this is to advise you that pursuant to 10 CFR 20.103(c) and (f), if you desire to receive credit for use of respiratory protective equipment at your facility after December 28, 1977, such use must be as stipulated in Regulatory Guide 8.15 rather than as specified in your B 06160710 770729 P
ADOCK 05 45
Y 2-Northeast Nuclear Energy Company current Technical Specifications. Based on the revocation provision of your current specification on respiratory protection and in the absence of prior written objection from you, we will include deletion of this speci-fication in an amendment of your Technical Specifications, approved after December 28, 1977.
No response to this letter is required.
Sincerely, hb y
