NUCLEAR REGULATORY COMMISSION OFFICE OF INSPECTION AND ENFORCEMENT WASHINGTON, 3.C.
20555 July 10, 1981 IE Circular No. 81-09: CONTAINMENT EFFLUENT WATER THAT BYPASSES RADI0 ACTIVITY MONITOR Description of Circumstances:
At Indian Point Units 2 and 3 and at H. B. Robinson Unit 2, licensee reviews of service water systems have ident', lied unmonitored effluent paths from contain-ment. Although containment cooler water effluent *s monitored, containment cooler fan motor cooling water bypasses the monitors by joining the containment cooler water effluent downstream of the radiation monitoring equipme..'.
This represents a potential unmonitored release path if the containment is at design pressure due to a design basis accident (DBA) and if leaks are present in the fan motor cooler system. Similar designs may exist at other plants. Appropriate monitoring of direct discharges (from containment to the environment following a DBA) having the potential to exceed the limits specified in 10 CFR Part 20 is required.
Recommended Actions.:
1.
All water system effluents that are not automatically isolated by a high-containment pressure containment isolation signal and that flow directly to the environment from containment should be reviewed to determine whether or not a pathwa exists for "significant" unmonitored discharge. A "signif-icant" discharge, for purposes of this circular, is a discharge where projected concentrations in unrestricted areas are likely to exceed the concentrations listed in 10 CFR Part 20, Appendix B, Table II, column 2, with the containment at design pressure due to a design basis accident and with maximum credible leakage, such as a single completely severed cooler tube, assumed to be present in the water system inside containment.
You may take credit for design pressure in the water system being higher than containment design pressure only for cases where neither single failures,-nor operation in degraded modes as permitted by Technical Specifications under a limiting condition of operation (LCO), are likely to result in operation of the water system at water pressures lower than the containment design pressure.
2.
All water system effluents that are not automatically isolated by a high-containment pressure containnent isolation signal and that flow directly to the environment from containment should be reviewed to determine whether or not any "significant" radioactive discharge can be isolated once it is detected. The review should include evaluation of the capability of the system to be isolated without interruption of ary safety-related functions.
Isolation of the system's inlet as well as its discharge may be required
