(see Appendix E to this guide) used for entering data into the NRC's computer-based file of information concerning licensee events. (Instructions for completing these licensee event report forms7 are issued individually to each licensee.) Information provided on the licensee event report form should be supplemented, as needed, by additional narra tive material to provide complete explanation of the cir cumstances surrounding the event. (1) Reactor protection system or engineered safety feature instrument settings which are found to be less conservative than those established by the technical specifications but which do not prevent the fulfillment of the functional requirements of affected systems. The following are examples: (a) One of the four scram dump volume level switches failed to operate during surveillance test. (b) One of four reactor low-pressure switches operated at 885 psig instead of LSSS value of 900 psig. (c) During test, one out of four under voltage relays failed to perform its function of tripping a reactor trip breaker. "(2) Conditions leading to operation in a de graded mode permitted by a limiting condition for operation, or plant shutdown required by a limiting condition for operation. The following are examples: (a) Core spray pump breaker tripped after 20 minutes during test. Trip unit was found to be defective, declared inoperable, and repaired. (b) Safety injection pump failed to start following system initiation. Required surveillance on redundant components was successfully completed. (c) One of the two centrifugal charging pumps became inoperable because of a faulty bearing. Redundant pump operability was confirmed. Note: Routine surveillance testing, instrument calibra tion, or preventive maintenance which require system configurations 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
