-l v..
1.
Report No.
50-302/77-78 2.
Facility:
Crystal River Unit #3 3.
Report Date:
3 August 1977 4.
Occurrence Date:
11 July 1977 5.
Identification of Occurrence:
Failure to analyze Dose Equivalent Iodine 131 upon a power change greater than 15%
within a one hour period contrary to Table 4.4-8 of Technical Specification 4.4.8.
6.
Conditions Prior to Occurrence:
Mode 1 power operations.
7.
Description of Occurrence:
At 1130 when reviewing turnover from the previous shift, the chief Chem / Rad technician discovered that the DE-I 131 was not analyzed upon a power change of 30%
~
within one hour. The Chem / Rad personnel were not notified of the power escalation as required by the special condition surveillance plan SP-442. The analysis was immediately initiated and analyses were made upon subsequent power changes, substantiating the DE-I 131 remained within acceptable limits.
g Designation of Apparent Cause:
The cause of this occurrence is attributed to procedural inadequacies in that the Chem / Rad personnel were not notified of power escalation.
9.
Analysis of Occurrence:
During power escalations the Iodine spiking phenomena can cause DE-I 131 to exceed the allowable Tech Spec limits.
10.
Corrective Action:
Changes to the operating procedures dealing with power changes have been initiated to insure notification of Cham / Rad personnel upon power level changes greater than 15%/ hour.
11.
Failure Data:
This is the first occurrence of this event.
