Information Notice No. 88-97, SUPPLEMENT 1: POTENTIALLY SUBSTANDARD VALVE
All holders of operating licenses or construction permits for nuclear power
This supplement is being provided to update information concerning potential
problems resulting from the manufacture and distribution of valve replacement
parts that may be substandard. It is expected that re-cipients will review the
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:
On October 21, 1988, Consumers Power Company (CPCo) submitted a 10 CFR Part 21
report to the NRC regarding valve internals for Masoneilan-Dresser Industries
(M-D) valves that were found to be manufactured by companies not authorized to
manufacture M-D valve parts. The M-D valve internal replacement parts were
procured as non-safety-related from Sample-Webtrol Controls Incorporated
(S-W), Livonia, Michigan, an authorized M-D sales representative. S-W records
indi-cate that all of the parts were manufactured by and procured from either
Cor-Val or Control Valve Specialists, Incorporated (CVS), both of whom are
located in Houma, Louisiana. Some of the parts were found to be dimensionally
and, in some cases, metallurgically incorrect.
On December 22, 1988, CPCo updated its October 21, 1988, 10 CFR Part 21
report. CPCo identified an additional 13 parts that were not genuine M-D
parts. These parts were procured by CPCo from H. H. Barnum, the M-D
authorized sales repre-sentative that preceded S-W. Six valve plug retaining
pins were found to have undersized expanded diameters. Five of the six pins
were supplied to H. H. Barnum by the M-D Houston facility, although M-D could
not determine the manu-facturer. Seven valve seat rings were found to be
dimensionally incorrect. Two of the seven seat rings were manufactured by
CVS; however, the manufacturer of the remaining five has not been determined.

On March 8, 1989, discussions with M-D and CPCo personnel revealed that 15
additional M-D valve internal replacement parts (out of 239 parts inspected)
recently were found to be nonconforming. CPCo procured the parts from either
S-W Controls or H. H. Barnum. Twelve of the fifteen nonconforming parts were
identified by either tags or packaging that indicated the parts originated
from the M-D Norwood, Massachusetts, facility. The origin of the remaining
three nonconforming parts has not been determined. At this time, the
manufacturer of the 15 nonconforming parts has also not been determined.
From a review of the circumstances, it appears that potentially substandard
valve internal replacement parts may possibly enter the nuclear parts supply
system either directly from secondary source manufacturers (e.g., CVS and
Cor-Val) or from the distribution centers of original equipment manufacturers.
In the examples discussed, a licensee ordered parts for safety-related
applications as commercial grade and failed to adequately verify that the
parts would perform their function. The authorized distributor procured the
parts from both the original equipment manufacturer and secondary sources
without ensuring, in all cases, that the parts were equivalent. In addition,
the original equipment manufacturer purchased parts from subcontractors and
did not adequately verify that the parts would fulfill their function.
No specific action or written response is required by this information notice.
