UPDATE: The vendor, Technology for Energy (TEC), had reported on 10/26/99
that the RTV-738 sealant used in TEC Valve Flow Monitoring System could
not be demonstrated to meet containment qualification conditions. The
vendor stated that the recommended installation procedure was not used
during a 1980 qualification test.  The vendor has conducting a new set of
tests to demonstrate that the accelerometer to hardline cable junction
can be qualified using RTV-738 sealant and also using Raychem heat
shrink.  A full range of thermal aging, radiation aging, seismic testing,
and LOCA testing demonstrated that the RTV-738 protected the junction in
a harsh environment.  Therefore, the junction configuration does not
create a substantial safety hazard and no industry corrective action is
required.

SOURCE DOCUMENT: LETTER         REVIEWER: REXB, T. Koshy

Westronics, Inc., a vendor of commercial grade and safety-related
recorders, reported that five Westronics series 1200B commercial grade
recorders caused a short to ground upon installation at Grand Gulf Unit
2. The harness assembly drawing for direct-current power input,
Westronics Part Number HN 101168, could have been misinterpreted
regarding wire color coding or pin location, thereby resulting in a power
to chassis short. The vendor states that no field failures of Westronics
series 1200B safety-related recorders have been reported. Other
potentially affected nuclear power plants are River Bend and Perry. The
vendor notified all three customers.

The NRC will post ensuing reports on this subject on its website at

ABB Power T&D Company, a vendor of electric circuit breakers, reported
that during refurbishment of 4-kilovolt ABB Type HK breakers at the Cook
nuclear power plant, the hardness of trip rollers, ABB Part Number
180097A00, was found below the minimum hardness specification, Rockwell C
50-55. The vendor will notify all customers who purchased this product.

Subject: Part 21 - Diaphragm valves may not achieve design
         bubble-tight shutoff


Discussion:

VENDOR: ITT Industries                  PT21 FILE NO: mm-03-0

DATE OF DOCUMENT: 12/14/99              ACCESSION NUMBER: ml993610132

SOURCE DOCUMENT: EN 36512               REVIEWER: REXB, R. Benedict

ITT Industries, a vendor of valves, reported that testing and analysis
indicated that three-inch diaphragm valves with 3250L actuators may not
be capable of bubble-tight shutoff at customer-specified operating
conditions. These valves were supplied to the nuclear power industry for
design pressures up to 200 psig. They were factory-tested at or above
shutoff pressure specified by design or ASME Section III requirements.
The vendor's testing and analysis indicated that bubble-tight shutoff as
low as 147 psig is statistically possible. Thus it is possible that a
valve maintained or repaired with new components or subassemblies might
not have sufficient actuator thrust to shutoff against the specified
pressure.

Affected facilities include Westinghouse, Bellefonte, Waterford, Davis
Besse, Duane Arnold, Diablo Canyon, Indian Point 2, Surry, Turkey Point,
St. Lucie, and Oconee. The vendor notified these customers.
