Narrative Reportfor LER 50-366/1982-137

On December 6, 1982, following a reactor trip, an isotopicanalysis for Iodine revealed the reactor coolant activity wasapproximately .357 micro-curies per gram DOSE EQUIVALENT I-131(DEI-131), reference Deviation Reports 2-82-305 and 2-82-307.This is contrary to Technical Specifications 3.4.5.a. Thereactor coolant activity exceeded 0.2 micro-curies per gramDOSE EQUIVALENT I-131 for a period of 34 hours during theevent. Results of the isotopic analyses are included asAttachment 1 to this report. Technical Specifications 3.4.5,Action 2b was violated when the required analyses were notperformed at 4 hours, and again at 8 hours into the event,reference Deviation Report 2-82-306. The health and safetyof the public were not affected by this non-repetitive event.

The cause of the high reactor coolant activity has been attributedto the leakage of a fuel rod. At 0745 on 12/7/82, the activitylevel returned to within limits; therefore, the 4-hour samplingwas terminated. At 1700 on 12/7/82, the reactor coolant activitywas found to be 0.789 micro-curies per gram DEI-131. Samplingand analysis every four hours was performed until 12/8/82 at1715 when reactor coolant activity returned to within limits.Additional information required per Technical Specifications 3.4.5,Action b.1 is included as Attachment 2 to this report.

The failure to perform isotopic analyses in two cases was due toan error in the computer software. The computer is designed toindicate when a limit is exceeded; however, the printout on the,

initial analysis indicated "No Tech. Specs. Limits Were Exceeded."The software was modifful to reflect the correct limits, andsubsequently to inform laboratory personnel to perform additionalsampling and analyses. The reactor coolant was assumed to begreater than Tech. Specs, limits of 0.2 micro-curies / gram perDEI-131 for the 8 hours of missed sampling in order to assure thelimiting conditions for operation pertaining to Tech. Specs.3.4.5 would not be violated.

3. Clean-up flow remained at approximately 100gpm until 12/6/82at 1806 when a reactor trip resulted in the isolation of the

i RhCU system. On December 7 at 0619 the RWCU system was returnedto service.
