SUPPLEMENTARY INFORMAT' ION

1. Report.No. 50-302/77-72 .

2. Facility:. Crystal River Unit #3

3. . Report Date: 22 July 1977

4. Occurrence Date: 30 June 1977 -

5. Identification of Occu-ence:

Failure to. calibrate a tm '" f regen gas chromotograph with specified gas mixture as prescribed by Techni . .. ification Surveillance Requirement 4.6.4.1.

6. Condition Prior to Oct Mode 1 power operation.

7. Description of Occurrence: i' During a review of the surveillance procedure for calibration of hydrogen gas ~

analyzer SP-730, it was discovered that the gas chromotograph, channel 112, had been calibrated using the wrong calibration gas mixture. 100% hydrogen had been used instead of mixtures containing one volume percent hydrogen, balance nitrogen.

and four volume percent hydrogen, balance nitrogen as specified by Technical

~

Specifications. The chromotograph was re-calibrated using the correct gas mixtures j and restored operable.

8. Designation of Apparent Cause:

I

! The Chem / Rad technician failed to follow the surveillance procedure which prescribed-the correct calibration gas mixtures as prescribed by Technical Specifications.

9. Analysis of Occurrence:

The safety and health of the plant and public were not affected,. as a redunda".t H2 analyzer was available and operable. )

10. Corrective Action. j l

Chem / Rad follow-up report F.U.R.77-175 has been posted and reviewed by Chen/Ra4 1 technicians to insure compliance with the surveillance procedure.

l l 11. Failure Data:

1' This was the first occurrence of this event.
