IE Bulletin No. 79-01B
Supplement No. 2
Date: September 30, 1980
ENVIRONMENTAL QUALIFICATION OF CLASS IE EQUIPMENT
Enclosed are the generic questions and answers which resulted from
NRC/Licensee meetings in NRC Regional Offices during the week of July 14,
1980 regarding environmental qualification of Class 1E equipment in use at
power reactor facilities. These answers address specific questions asked
during the meetings. Due to the generic nature of some of these questions,
the staff is issuing them as a bulletin supplement. The regional meetings
highlighted the fact that in some cases, the scope and depth of the 79-01B
review was not clear to licensees. Therefore, these answers may affect your
79-01B submittal. These submittals are required by a separate order to be
completed by November 1, 1980.
Some answers given in Supplement No. 1 to IEB-79-01B are superseded by these
answers. For example, in Bulletin Supplement No. 1, issued on February 29,
1980, the answer to question No. 5 specified that TMI lessons learned
equipment was not included in the review. However, due to the extension of
the response date from April 14, 1980 to November 1, 1980, this equipment is
now being addressed since its installation is either complete or required
before the issuance of the February 1, 1981 SER. (See Question No. 21 of
this Supplement.)
No specific response is requested by this Supplement; however, all answers
contained in the enclosure to this Supplement should be carefully reviewed
and considered for applicability in your response to IEB 79-01B.
IE Bulletin No. 79-01B was issued under a blanket GAO clearance (B180225
(ROO72); clearance expired July 31, 1980) specifically for identified
generic problems. Supplement No. 2 to Bulletin 79-01B is for information,
hence no GAO clearance is required.
