Perry Nuclear Power Plant Final Report on
Dear Mr. Keppler:
Post-LOCA H Analyzers y
This letter is the final report on the deficiency concerning Post-LOCA H, j
Analyzers required by 10CFR50.55(e). This problem was first identified to Mr. Jack Hughes of the NRC Region III, Of fice of Inspection and Enforcement on April 22, 1980, by Mr. M. R. Edelman of The Cleveland Electric Illuminating i
l Company. Additionally, an interim report dated May 22, 1980, was sent to you documenting the problem and the course of action to be taken.
Description of Deficienev The Cleveland Electric Illuminating Company avarded a contract to Comsip Incorporated for the design, f abrication, ass.mbly, testing, inspection and j
delivery of the hydrogen analyzer systems for the Perry Nuclear Power Plant-Units 1 and 2.
During a functional testing of one of the units, a pump failed i
because one of the panel outlet v Ives was closed when the pump was started.
This design did not consider that excessive outlet pressure of the sample pump could cause mechanical separation of the connecting rod and crank shaf t, which in turn, could rupture the pump diaphragm.
<l An,1ysis of Safety Implication In our interim report, dated May 22, 1980, we identified two (2) potential safety hazards:
1.
Up to one (1) liter of containment gas could be released into the outside atmosphere, should the failure as defined above occur; and/or 2.
If the input / outlet valve is closed while the pump is in operation or if the containment isolat!
valve inside the containment is closed, there is a risk in damaging the system, thereby rendering the system inoperable.
