DESCRIPTION OF EVENT On 4/3/90, with the plant operating at 100% power, it was identified that the flow transmit-ters that supply Advanced Off-Gas (A00) System Fle? Indication had not been calibrated in the last eighteen months as required by Vermont Yankee Technical Specifications (TS). There are three flow transmitters (FT-0G-1902, 1904 and 1905) (EIIS=FT) which are used to provide 1 A0G flow indication. Any or ' " the three flow indicators can be used to meet the TS {

requirement depending on the system operating configuration. The flow indicators had been calibrated on 3/1/89, however, the flow transmitters that supply them were last calibrated j on 9/15/87. Upon identification of this condition, a full loop calibration was performed I on the A0G Flow Monitor's, and based upon '-f e nd calibration data, no overall loop accu-racies were exceeded.

Investigation into the cause of this evem revealed that the pro p surveillance interval I for calibrating the flow monitoring equipment was included on Vermont Yankee's Master Surveillance List (MSL), a document utilized to track such activities. However, the P requirement to perform the survefilance was not identified as being TS. The basis for the flow monitor surveillance frequency was identified on the MSL as being administrative, in which case the department responsible for the surveillance h'as the flexibility to reschedule l testing as needed. This flexibility is not permitted when the surveillanas is required by I TS.

In January, 1984, Proposed Technical Specification Change #78 was submitted to the NRC for review and approval. Included in this change were revisions based upon NUREG 0472, Standard Radialogical Effluent Technical Specifications (RETS). The addition of TS surevillance ,

requirements for the flow instruments occurred when the Proposed Change was issued in Octobe., 1984 as TS Amendment #83, with an effective date of April, 1985. ,

i When TS Amendment #83 was issued, the procedure used to calibrate the flow instrumentation I was revised to indicate it contained TS equipment. However, the MSL was not revised to reflect that the basis for the flow monitors to be calibrated changed from an Administrative Requirement to a TS Surveillance Requirement.

CAUSE OF EVENT The root cause of this event is personnel error. The responsible department provided incom- l plete opdate information to revise the MSL upon issuance of Technical Specification Amendment #83. The TS surveillance requirement for flow monitor calibration was not added l l

to the MSL and this resulted in insufficient control of this activity.

Contributing Factor:

The section of TS that contains the flow monitor surveillance requirements (RETS) does not contain specific instrument numbers, therefore, interpretation of the applicable requirement is necessary.
