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 Chem / Rad follow-up report F.U.R.77-175 has been posted and reviewed by Chen/Ra4 technicians to insure compliance with the surveillance procedure.
l 11.
Failure Data:
1 This was the first occurrence of this event.
