Information Notice No. 88-48, SUPPLEMENT 1: LICENSEE REPORT OF DEFECTIVE
REFURBISHED VALVES
Addressees:
All holders of operating licenses or construction permits for nuclear power
reactors.
Purpose:
This information notice supplement is being provided to present additional
information regarding the valves discussed in Information Notice 88-48. It is
expected that recipients will review this information for applicability to
their facilities and consider actions, as appropriate, to avoid similar
problems. However, suggestions contained in this information notice do not
constitute NRC requirements; therefore, no specific action or written response
is required.
Description of Circumstances:
Information Notice 88-48 discussed information from Pacific Gas and Electric
(PG&E) about a potential problem with 2-inch valves that were leaking steam at
the bonnet and packing.
The NRC received a letter from the Henry Vogt Machine Company (Vogt Company),
dated August 1, 1988, stating its position on the Diablo Canyon valve matter
and providing additional information on the distinguishing features of its
valves. The letter received from the Vogt Company is attached. The letter
also indicates the Vogt Company belief that the Diablo Canyon valves were
counterfeit and not refurbished Vogt valves and corrects a reference to the
Vogt figure number in the original information notice.
