1.
Report No.
50-302/77-68 2.
Facility:
Crystal River Unit #3 3.
Report Date:
15 July 1977 4.
Occurrence Date:
24 June 1977 5.
Identification of Occurrence:
Failure to sample / analyze Reactor Coolant letdown for dose equivalent I-131 at 4 hour4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> interval as required by Technical Specification Action Statement 3.4.8.a.
6.
Conditions prior to Occurrence:
Mode 3 hot shutdown following a Reactor trip.
7.
Description of Occurrence:
As reported in LER 77-67, following a Reactor trip, the dose equivalent I-131 was d
detemined to be greater than 1 pc/ gram. At 2000 it was discovered that the Tech Spec required 4 hour4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> time frequency to sample / analyze the Reactor Coolant for D.E.I-131 had been exceeded by 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />. A sample / analysis was immediately initiated and subsequent sampling met the time frame require.1,nts of Tech Specs.
8.
Designation of Apparent Cause:
Failure of Chem / Rad technician to follow surveillance procedure SP-709 frequency of sampling requirements.
9.
Analysis of Occurrence:
There was no safety hazard to the plant or general public as samples taken indicated a decreasing I-131 activity.
10.
Corrective Action:
Chem / Rad follow-up report FUR 77-174 has been posted to insure technicians review the time frequency of SP-709.
11.
Failure Data:
This is the first occurrence of this event.
