Content:
ations as described in items 2.b(l) and 2.b(2) need not be reported except where test results them selves reveal a degraded mode as described above. (3) Observed inadequacies in the implementa tion of administrative or procedural controls which threaten to cause reduction of degree of redundancy provided in reactor protection systems or engineered safety feature systems. The following are examples: (a) One of the three diesel generators tripped from high temperature because cooling water valves were lined up incorrectly. (b) Isolation valve for a low-pressure trip switch was found closed with system pressure locked in. Trip of switch would not occur at low pressure. Improper return to operation following maintenance was the cause. (c) Failure to perform surveillance tests at the required frequency. (4) Abnormal degradation of systems other than those specified'in item 2.a(3) above designed to contain radioactive material resulting from the fission process. For example, a through-wall leak in a liquid waste storage tank. Note: Sealed sources or calibration sources are not included under this item. Leakage of valve packing or gaskets within the limits for identified leakage set forth in technical specifications need not be reported under this item. 1.16-5 3. Unique Reporting Requirements The above reporting program will in general satisfy the reporting requirements necessary for compliance with Appendix A technical specifications. This program may need to be supplemented or modified because of unique plant design features or other factors. The need for a supplemental or modified program will be deter mined on a case-by-case basis and so designated in individual operating licenses. 4. Events of Potential Public Interest The types of events listed below are frequently of high public interest. While some of the events may not be reportable by regulation or defined in other parts of this guide, the Director of the appropriate NRC Regional Office, or his designee, should
