NUCLEAR REGULATORY COMMISSION

Proposed Generic Letter Titled ``Mark I and Mark II Steel
Containments;'' Decision Not To Issue

AGENCY: Nuclear Regulatory Commission.

ACTION: Notice of decision not to issue a proposed generic letter.

-----------------------------------------------------------------------

SUMMARY: On November 21, 1992, the NRC published a proposed generic
letter in the Federal Register (57 FR 54860) for public comment. The
proposed generic letter recommended actions to be taken by licensees of
operating boiling-water reactor plants with Mark I and Mark II steel
containments to implement certain inservice inspection procedures that
would prevent a potential inadvertent loss of containment integrity and
maintain continued conformity with their licensing bases. The comment
period for this proposed generic letter expired on December 21, 1992.
Comments were received from eleven organizations; six from nuclear
utilities, two from industry groups, two from architect/engineering
companies, and one from a citizens group. Only the citizens group
supported the issuance of the proposed generic letter. As an
alternative to the proposed generic letter, the two industry groups,
the Nuclear Management and Resources Council (NUMARC) and the Boiling
Water Reactor Owners' Group (BWROG), proposed a model containment
inspection program (CIP) which they believe to be cost effective and to
be able to resolve the concerns of the NRC staff. The six nuclear
utilities and two architect/engineering companies indicated their
support for the CIP. Concurrent with the proposal of the CIP, the
American Society of Mechanical Engineers (ASME) has developed
containment inspection criteria that the NRC will consider for
implementation through the rulemaking process. The NRC staff has
determined that the concerns with Mark I and Mark II containment
inspections will be best addressed within the context of any NRC
rulemaking on the ASME containment inspection criteria. Therefore, the
NRC has decided not to issue the proposed generic letter.

DATES: Not applicable.

ADDRESSES: Not applicable.

SUPPLEMENTARY INFORMATION: The NUMARC and BWROG CIP is also addressed
in a NRC letter to Mr. Lesley A. England, BWROG Chairman, dated
February 3, 1994. This letter is available in the Public Document Room
under accession number 9402090256.

Dated at Rockville, Maryland, this 4th day of April 1994.

For the Nuclear Regulatory Commission.
Andrew J. Kugler,
Acting Chief, Generic Communications Branch, Division of Operating
Reactor Support, Office of Nuclear Reactor Regulation.
