NRC Regulatory Issue Summary 2000-21: Changes to the Unplanned Scram and
Unplanned Scram with Loss of Normal Heat Removal Performance Indicators
dated October 31, 2000.
The U.S. Nuclear Regulatory Commission is issuing this Regulatory Issue
Summary (RIS) to inform power reactor licensees that a 6-month pilot test
will be conducted to evaluate changes to the "unplanned scrams per 7,000
critical hours" and the "unplanned scrams with loss of normal heat
removal" performance indicators (PIs) that are intended to minimize the
potential for unintended consequences.

Licensee/Facility: Notification:
Part 21 Database MR Number: H-00-0064
Itt Industries Date: 10/31/00
Subject: Part 21 - Potential Failure of Transducer in Harsh
Accident Environment
Discussion:
VENDOR: ITT Industries PT21 FILE NO: mm-21-0
DATE OF DOCUMENT: 10/16/00 ACCESSION NUMBER:
SOURCE DOCUMENT: EN 37427 REVIEWER: REXB, E. Goodwin
ITT Industries, an instrument vendor, notified the NRC that an
inappropriate bonding process was used in the manufacture of an IEEE I/P
transducer, causing it to not conform with test and performance
requirements of standards IEEE 323, "Qualifying Class 1E Equipment for
Nuclear Power Generating Stations," and IEEE 344, "Recommended Practice
for Seismic Qualification of Class 1E Equipment for Nuclear Power
Generating Stations." The transducer would potentially not perform its
intended safety function during a seismic event involving high radiation
or high temperature steam. Product model numbers involved are:
GT25CA1826 GT45CA1826 GT65CA1826
GT25FA1826 GT45FA1826 GT65FA1826
Domestic nuclear power utilities that may be affected include Duke
Energy, Commonwealth Edison, New York Power Authority, Northeast Nuclear
Energy, Omaha Public Power District, Alabama Power, Detroit Edison, and
GPU Nuclear. The vendor expects to conclude its analysis by December 15,
2000, and to make replacement units available by February 15, 2001.
The NRC will post ensuing reports on this subject on its website at
http://www.nrc.gov/NRC/PUBLIC/PART21/2000.
