'QCCIDENT RADIATION MONITOR SPECIAL REPORT
~Back round:
The"Waste Pzocessing Building Vent Stack 5 wide range gas monitor (WRGM)
ARM-3.WV-3546 1
was declared inoperable under Technical Specification 3.3 3 11, Radioactive Gaseous Effluent Monitoring Instrumentation, an5 Technical Specification 3.3.3.6, Accident Monitoring ZastrumerRation, on December 12, 1987, at 1729.
This was due to <<epeatad spiking into a high alarm that could not be attributed Xo actual. radioactivity in the process flow going up ver: stack 3 Efforts to ~turn'e monitor to operable status within 7
days hava been ~successful.
Therefore, this special report is submitted pursuant:tu Technical Specification 3.3.3.6, Action C.
Descxi tion'af Event.-.
On december 62~
- 1987, the Waste Processing Building vent stack 5
WRGH began 'apiking::into the high alarm.
Portable grab sampling of the -
stack
".:;proctess flow revealed no evidence of high radioactiv~.'haanonitor was declared inoperable at 1729 and a
~Je request.smitten to test and repair the monitor.
Xba " compensatory:."actions required by Technical Specifications 3 3"'3.11, Table 3 ~3,3, Actions 46, 49, and 52 were taken.
Since tba " particxilat:e-ieihne"gas (PIG) monitor ARM-lWV-3546, which samples stack
',3 in: parallel with the WRGM, was still operational, tha garticu1ata anxl 3.odine pre filters for the WRGM were switched to '%he PIG
'. ~e'.MG monitor then provided the primary sampling far.noble gas-:".whelm the WRGM was inoperable.
All compensatory nmrsures for'sgasenus effluent and accident monitoring for stack 5
wane. satisHad Cense:
Mai'ntenance~na< the monitor revealed a defective photo-multiplier (P 'K.) tube',on".the 1ow range channel.
This tube was replaced and the problem
,>was
,corrected.
The low range channel was
~fac to~ye ca19%ra ted in accordance with MST-I0375, and the monitor
~"'.
may to be returned to service on December 2B~!'-1987 Before the system could be declared operational
~>the high range channel failed.
Another work request was.issued.~by.'perat:ions personnel to test and repair the high range channe1.'his work was begun on December 30,
- 1987, but has not ".been completed.
To date, maintenance personnel have not yet bean able to.determine the problem with the high range channel.
MEM/HO-8800010/2/Osl;
a Corrective Actions.
- The corrective actions taken to restore the monitor to operable status were Xo replace the photo-multiplier tube in the low range channel and to recalibrate the monitor.
This was completed on
. December 28~
1987.
Work is still in progress to determine the
'='ause of the additional failure of the high range channel.
An
- c estimated campletion date for this work is not available at this
-== time.
The results of the subsequent repair work will be submitted a as a supplement to this report.
