w ENCLOSURE BELLEFONTE NUCLEAR PLANT UNITS 1 AND 2 SEISMIC QUALIFICATION OF B&W EQUIPMENT ON TVA PANELS NCR BLN BLP 8011 10 CFR 50.55(e)
THIRTEENTH INTERIM REPORT Description of Deficiency A number of Babcock and Wilcox (B&W) supplied instruments are intended for installation on TVA's freestanding, open, local instrument panels. Because of imprecise specifications in a TVA procurement document, the instrumentation listed below and supplied by B&W has not been seismically qualified to a response spectra that is compatible with the response spectra for TVA local instrument panels. Consequently, the responsibility for this deficiency is TVA's.
A list of the instruments to be qualified follows:
Type of Device Vendor Vendor ID No.
Differential pressure transmitter Bailey Meter Co.
Type N1BQ86221 Differential pressure transmitter Bailey Meter Co.
Type N2BQ74221 Differential pressure transmitter Bailey Meter Co.
Type N2BQ76221 Differential pressure transmitter Bailey Meter Co.
Type N2BQ85221 Differential pressure transmitter Bailey Meter Co.
Type N2BQ86221 Pressure transmitter Bailey Meter Co.
Type N2KS69221 Indicator meter Bailey Meter Co.
ES-342 Operator station Bailey Meter Co.
TT-10 Interim Progress As reported in our previous responses, the equipment in question was seismically tested to the higher "g" values of the correct response spectra.
The results showed that all equipment is qualified except the N2BQ74221 and N2BQ86221 transmitters and the TT-10 operator station. A contract was set up with Wyle Laboratory to retest the three devices. The results of Wyle's test were scheduled to be submitted to TVA on August 1, 1985. However Wyle did not meet this schedule, and they have rescheduled submission of the test results to October 18, 1985. TVA must evaluate these results and determine if the devices successfully passed the seismic test and are seismically qualified, and take appropriate corrective action if they are not qualified.
TVA will provide a final report on this deficiency upon completion, but no later than six months prior to fuel loading.
