GAMMA MONITORS NON-FUNCTIONAL
The following information was provided by the licensee via fax or email:
"Two gamma monitors on filters associated with the waste water treatment system were discovered to be non-functional during their monthly calibration check. These gamma monitors are designated as an Item Relied on for Safety (IROFS) and are used to prevent gradual long term accumulations of uranium from exceeding a safe mass.
"The system has been shut down and will remain down until the required safety function is restored.
"This condition is being conservatively reported under the requirements of 10CFR70 Appendix A b(2) due to two Failed IROFS although Framatome believes that the performance requirements of 10CFR70.61 are still met."
