SUPPLEMENTARY INFORMATION 1.

Repdre No.:

50-302/77-79 2.

Facility:

Crystal River Unit #3 3.

Report Date:

3 August 1977 4.

Occurrence Date:

8 J917 1977 5.

Identification of Occurrence:

Inoperability of gas chromatograph contrary to Technical Specification 4.6.4.1.

6.

Conditions Prior to Occurrence:

Mode 1 power operation.

7.

Description of Occurrence:

At 2150 the Fisher gas chromatograph failed to meet the calibration acceptance i

criteria as required by Technical Specifications. The 1 and 4 volume percent hydrogen, balsace nitrogen calibration would not meet the requirements due to apparent separation column degradation resulting in a loss of resolution. A replacement separation column was ordered and the gas chromatograph has been restored operable.

B,, Designation of Apparent Cause:

The cause of this event was the failure of the colum to perform its intended function.

9.

Analysis of Occurrence:

The safety and health of the plant and public were not affected as a redundant hydrogen analyzer was available and operable.

10.

Corrective Action:

A spare separation column will be maintained at all times in order that corrective action can be accomplished in a timely manner.

11.

Failure Data:

This was the first occurrence of this event. It was the second occurrence of the inoperability of this device. Refer to LER 77-72.
