ENCLOSURE 2 TENNESSEE VALLEY AUTHORITY BROWNS FERRY NUCLEAR PLANT RADIOACTIVE INOPERABLE EFFLUENT INSTRUMENTATION REPORT 8709030368 870828 PDR ADOCK 05000259 R PDR
II t Radioactive Ino erable Effluent Instrumentation are inoperable Hay 6, 1987.
for more than 30 days.
Re ort This report is to comply with Radiological Effluent Technical Specifications (RETS) section 3.2.0.2 and 3.2.K.2 reporting requirements for instruments that The RETS became effective at Therefore this report only covers the period from May BFN on 6
June 30, 1987. Because of significant technical specification changes, a large number of radioactive effluent monitoring instruments became technically inoperable on May 6, 1987. RETS were incorporated during a BFN administrative outage. Site resources were and still are endeavoring to resolve previously identified problem areas. Hodifications required to bring BFN effluent monitoring equipment into technical compliance with RETS competes for, resources with other regulatory driven modifications. This report explains why the inoperability of each instrument was not corrected in a timely manner.

Li uid Process Radiation Monitors BFN RETS Table 3.2.0 requires RHR Service Water Monitors (1 133, 1-90-134, 2-90-133, 2-90-134, 3-90-133, and 3-90-134) and Raw Cdoling Water Monitors (1-90-132, 2-90-132, and 3-90-132) to be operable when these systems are in service. Contrary to this requirement, these nine monitors were inoperable during the entire reporting period.
These monitors were declared inoperable because they were not designed to meet the requirements in RETS Table 4.2.D Footnote 2. This footnote requires that control room annunciation occur if instrument controls are not set in operate mode. Oesign Change Request 1687, revision 1, was written to correct this problem and was approved on September 29, 1986. Engineering Change Notices (ECNs) P0976 (Unit 1), P0977 (Unit 2), and P0978 (Unit 3) were issued August 7, 1987 and these modifications wi 11 be complete and the monitors will be fully operable by March 31, 1988.

Li uid Radwaste Effluent Instrumentation BFN RETS Table 3.2.0 requires the liquid radwaste effluent'onitor (90-130) and flow rate loop (77-60) to be operable during liquid radwaste releases.
Contrary to this requirement, these two instruments were technically inoperable during the entire reporting period.
The liquid radwaste effluent monitor was declared technically inoperable because it was not designed to meet the requirements in RETS Table 4.2.0 Footnote 1. Footnote 1 requires automatic isolation to occur if the instrument encounters an inoperative/downscale failure. The monitor was, however, in service and would have alarmed causing operator action to terminate release. Additionally, the required supplemental sampling.

The flow rate loop Instructions (SIs) to was be complete and meet the channel requirements were not written and performed.
the monitors calibration The will and be fully operable declared technically inoperable because Surveillance-functional test, flow rate loop (77-60) will by be fully calibrated and operable by October 31, 1987.

t Stack Radioactive Effluent Instrumentation The stack effluent noble gas monitors (90-147A and (90-271) were inoperable during Footnote 1 requires that stack noble gas calibrated using National Bureau of Standards B) and this reporting period.'FN the stack flow meter monitors (90-147A and (NBS)
RETS Table 4.2.K B) be traceable radioactive standards. NBS traceable calibrations were completed on April 13, 1987.
However, upgraded Surveillance Instructions (SIs) incorporating the new calibration results have not been approved and performed.
The stack flow meter is also inoperable because cal.ibration and functional SIs have not been approved and performed. Fuel was off-loaded for all three units and no fuel movements occurred during this period. Results of compensatory lab analyses of stack effluent indicated no anomolies.
The stack noble gas monitors and flow meter will be fully operable by September 30, 1987.

Bui ldin Ventilation Exhaust Monitors BFN RETS Table 3.2.K requires reactor/turbine building ventilation monitors (1-90-250, 2-90-250, and 3-90-250) and the radwaste building vent monitor (0-90-252) to be operable at all times and the turbine building exhaust monitors (1-90-249, 1-90-251, 2-90-249, 2-90-251, 3-90-249, and 3-90-251) to be operable during releases via this pathway. Contrary to this requirements, seven monitors (1-90-250, 2-90-250, 3-90-250, 0-90-252, 1-90-249, 1-90-251.
and 3-90-249) were not operable for over 30 days. Fuel was off-loaded for all three vessels and no fuel handling occurred during the period of inoperability. Compensatory lab analyses indicated no detectable noble gas activity in ventilation releases.
During the NBS traceable calibration of these radiation monitors in January 1987 by the vendor, Nuclear Measurements Corporation, they determined that the monitors did not meet the lE-6 LLD requirement of BFN RETS Table 4.2.K Footnote 6. In response to this deficiency, OCR 3421 was approved and ECNs meet the LLO requirements. This modification is complete on all ten monitors, but two monitors (2-90-250 and 0-90-252) are still inoperable because of sample pump maintenance problems. New sample pumps have been ordered and the remaining two monitors wi 11 be operable by December 31, 1987.

r Off as Posttreatment I
BFN RETS Table 3.2.K requires the offgas posttreatment noble gas monitors (1-90-265, 1-90-266, 2-90-265, 2-90-266, 3-90-265, and 3-90-266) to be operable at.all times. Table 4.2.K requires performance of functional tests and channel calibrations for these radiation monitors. Contrary to the requirements of Table 4.2.K functional tests and channel calibrations were not performed and the instruments were taken out of service. Surveillance Instructions for these monitors have been approved and monitors 2-90-265 and 2-90-266 were returned to service in July 1987. The remaining four monitors encountered sample pump problems. These pumps are being repaired and all posttreatment radiation monitors will be returned to service by September 30, 1987. The offgas systems were not in service during this period.
