The Severity Levels were assigned in accordance with the NRC Enforcement Policy (10 CFR Part 2, Appendix C).

ADM-29.5 requires the bypass of safety functions to be performed in accordance with written, approved procedures.
Contrary to the above Technical Specification requirements; Administrative Procedure ADM-29.5, Section 4.2, and Electrical Maintenance Procedure EMP-C-RT-24 were not followed on August 21, 1984, when Unit 2 18 1 train RPS reactor trip logic was bypassed during full power operation.
Procedure EMP-C-RT-24, which was used to replace the failed BF relay in the RPS, did not specify bypassing the 18 1 train reactor trip logic.
The 18 1 reactor trip bypass breaker was closed during the maintenance, and the 1A1 RPS train and breaker were fully operable as required.
This is a Severity Level V violation (Supplement I), and applies to Unit 2.
