TO ALL CONSTRUCTION PERMIT AND OPERATING LICENSE APPLICANTS
SUBJECT: ISSUANCE OF NUREG-0588, "INTERIM STAFF POSITION ON EQUIPMENT
QUALIFICATION OF SAFETY-RELATED ELECTRICAL EQUIPMENT"
A task force composed of members of the NRC staff has prepared a report
entitled "Interim Staff Position on Environmental Qualification of Safety-
Related Electrical Equipment" (NUREG-0588), dated November 1979. The report
provides the staff's resolution of the NRC's Generic Technical Activity A-
24, which is an "Unresolved Safety Issue" pursuant to SEction 210 of the
Energy Reorganization Act of 1974. Copies of this "For Comment" edition of
the report were mailed to all applicants on January 9, 1980. A notice of
issuance and availability was published in the Federal Register (Vol. 45,
No. 11, page 3124) on January 16, 1980. A copy of the notice is enclosed.
NUREG-0588 provides the NRC staff's technical positions on selected areas of
environmental qualification, and provides guidance and describes methods
which, when implemented, will ensure compliance with the Commission's
requirements. The areas addressed include requirements for establishing the
service conditions for areas inside and outside containment, to which
equipment should be qualified; the selection of the qualification methods to
be used for the equipment in these areas; and the preparation of
qualification documentation. This report also defines the applicability of
these positions to the different vintage plants undergoing a review for a
construction permit or an operating license, that are required to conform to
either the 1971 or the 1974 version of IEEE Standard 323.
In Implementing the positions described in NUREG-0588 the staff will require
that applicants for operating licenses document the degree to which their
qualification programs comply with the staff's positions described in NUREG-
0588, and their basis for any deviations. You will shortly receive, by
separate letter, a request for additional information to be inserted in
Section 3.11 of your Final Safety Analysis Report.
In addition, the staff plans to modify slightly its implementation of IEEE
Std. 323-1974. Regulatory Guide 1.89, issued in November of 1974, requires
that all CP applications for which a staff Safety Evaluation Report was
issued after July 1, 1974, should comply with the requirements of IEEE Std.
323-1974. It has been staff practice to require that all other applicants
comply with IEEE Std. 323-1971. This continues to be the staff practice with
the following exceptions.

.
TO ALL PWR AND BWR APPLICANTS - 2 - FEB 05 1980
Equipment which would normally be qualified in accordance with IEEE
Std. 323-1971, but which has not yet undergone qualification testing,
should be qualified in accordance with IEEE Std. 323-1974. In
implementing this guidance, the staff will use IEEE Std. 323-1974 and
the provisions of Sections 2 through 5 of the Category I positions
described in NUREG-0588 in assessing the adequacy of all equipment
purchased six months from the date of issuance of NUREG-0588. The
service conditions developed in accordance with Section 1, Category II
of NUREG-0588 may be used in meeting this requirement.
Beginning 12 months from the date of issuance of NUREG-0588, equipment
which must undergo requalification testing should also be qualified in
accordance with IEEE Std. 323-1974 and the provisions of Sections 2
through 5 of Category I positions described in NUREG-0588. The service
conditions developed in accordance with Section I, Category II may be
used in meeting this requirement.
Public comments are being solicited from interested organizations, groups,
and individuals. Because of the need to review and resolve any comments
received from the public, we do not anticipate full implementation of these
requirements until May 1980. However, in the interim, the positions
described in NUREG-0588 are being used as guidance to the staff in reviewing
applicants's qualification programs.
At the completion of the 60-day period, the staff will evaluate the comments
received and, if needed, will issue a supplement or revision to NUREG-0588.
The target for issuing the supplement or revision is late April 1980.
All comments on NUREG-0588 and this letter should be forwarded to Mr. Andrew
J. Szukiewicz, Instrumentation and Control Systems Branch, Nuclear
Regulatory Commission, Washington, D. C. 20555 by March 17, 1980.
Sincerely,
D. F. Ross, Jr., Acting Director
Division of Project Management
