FITZPATRICK NUCLEAR POWER PLANT DOCKET N0. 50-333 ATTACHMENT TO LER 79-065/03L-0 Page 1 of 1 During normal startup operations, the Rod Sequence Control System failed in such a manner as to not allow normal control rod insertion or with-drawal . The scram function for control rods remained unaffected. The lied Sequence Control System maintained control of the rod withdrawal st:quence by not allowing any motion, thus the system performed its ir. tended function as required by Technical Specifications Appendix A, Paragraph 3.3.B.3.a.
Since the Rod Sequence Control System maintained control of the withdrawal sequence as noted above, the event did not represent a significant hazard to public health and safety.
Investigation revealed a failed relay on one of the printed circuit boards associated with Control Rod Group 3.
Replacement of the relay restored normal operation of the system.
