O 50-445/80-20 50-446/80-20 Appendix 3 NOTICE OF DEVIATION Based on the results of the NRC inspection conducted during September 1980, it appears that certain of your activities deviate from commitments made in your Final Safety Analysis Report (FSAR) as indicated below:
Incorrect Design of Pressurizer Sprav Control Valve Piping FSAR, Section 5.1, Figure 5.1-1, Note 2 states, " Spray pipe sloped to provide water seal between pressurizer and spray valves.
Valves to be a minimum of 10 ft. below pressurizer top."
Contrary to the above:
The Resident Reactor Inspector obseEved that the partially installed pressurizer spray control valves were above the top of the pressurizer.
Subsequent review of the engineered design as displayed on isemetric drawings RC-1-RB-016, 017 and 018 established that valves 1-PVC-455B and C are placed 1 foot 4 inches and 2 feet 11 inches, respectively above the top of the pressurizer rather than at least 10 feet below.
l This is a deviation.
