NARRATIVE

REPORT FOR LER 50-366/1981-007 On January 24tYi and 25th, 1981 while the unit was in cold shutdown the reactor coolant sample was taken from the fuel pool sample line.

ThV technician taking the sample was filling in on the weekend for the technician that normally takes the samples.

No communication

- occurred between the 2 technicians.

The supervisor on duty was aware that the sample location had changed from the fuel pool to the RHR loop 'that was..in service for the reactor vessel.

The normal sample

point, the reactor coolant sample line, was out of service.

The reactor unter clean up system was not in service so a sample could not be taken from either.

Saveral days earlier the RIIR loop had been started up and the fuel was being transferred from the fuel pool to the reactor vessel.

When all fuel is in the fuel pool, reactor mC coolant samples are taken from the fuel pool sample lines.

The last time the technician had sampled for reactor coolant he had taken the sample from the fuel pool sample lines which was correct at that time.

The samples were taken without incident and the data reviewed.

During the ensuing corversation the technician noted the sample came from the fuel pool not the RIIR loop.

As a result the sample was pulled from the RilR loop on January 26, 1981 and no limits were exceeded.

There were 2 violations of section 4.4.4.c because the conductivity was not checked every 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> which is required when the continuous recording conductivity monitor is inoperable.

There were no effects upon public health and. safety due to this event.

No previous LER has-been issued for this violation on Unit 2 although several'have been issued on Unit 1.

This series of events has never occurred before and the persons involved have been re-instructed on proper communicaticas, its value and effectiveness.
