CONTAINMENT AIR SAMPLING SYSTEM PLACED OUT OF SERVICE FOR EXCESSIVE LEAKAGE

The licensee discovered that two automatic closure containment isolation valves (CM-V-1 and 3) on the containment air sampling system process lines have excessive leakage. This was discovered as a result of maintenance troubleshooting of leakage found in the containment air sampling system during the annual containment atmosphere post-accident sampling system surveillance. The redundant isolation valves have been closed, and the monitor can remain out of service for 72 hours with 8-hour grab samples being taken of containment atmosphere per Technical Specification 3.1.8. Work is underway to install a passive barrier (pipe cap) on the inside containment end of each process line, after which the associated valves will be repaired.

The licensee notified the NRC Resident Inspector.

NOTIFIED THE STATE OF FLORIDA, DEPARTMENT OF HEALTH, OFFICE OF RADIATION CONTROL

The State of Florida, Department of Health, Office of Radiation Control was notified of the following event.

An individual departing alarmed the portal monitor. Upon investigation it was discovered that the individual's jacket contained a "hot particle." The individual is a French national working on site on the Appendix R (Mecatiss) project. The individual was aware of the contamination and had exited French nuclear plant(s) with out any questions. The particle was removed and the jacket returned. The particle was determined to be Co-60 and reads 450,000 dpm by direct frisk with an RM-25 meter with standard pancake probe. The Beta reading was 8 millirem per hour, open window, with an RO-20 survey instrument. This has been determined to be reportable under 10CFR20.2203(a)(3)(ii), and a 30 day written report will be issued.

The licensee notified the NRC Resident Inspector and Region 2 Division of Reactor Safety (Bruce Mallett).
