L Dear Mr. Barkhurst:

SUBJECT:

INTERFACINGSYSTEMLOCAINSPECTION(50-382/90-200)  !

l We are enclosing the report on the interfacing system loss-of-coolant accident

(ISLOCA) inspection performed from July 30 through August 10, 1990, at the

t

i

Waterford 3 nuclear power plant. The Nuclear Regulatory Counission (NRC) staff  :

,

from the Office of Nuclear Reactor Regulation, Region IV and NRC contractors

l

L conducted this inspection. Wediscussedtheinspectionfindingswithmembers

L of your staff during an exit meeting on August 10, 1990.

,

[ ' The NRC inspection team evaluated specific plant design features, systems,

equipment, procedures, operations activities, and human actions that could

affect the initiation or progress of an ISLOCA. The team focused its revitw on

the high-pressure safety injection, shutdown cooling, and low-pressure safety )

injection systems, with a cursory review of the chemical anc volume control i

system.

]

!' The team found that the pressure isolation valves within syst"ms interfacing

with the reactor coolant system pressure boundary at Waterford 3 were

adequately maintained and tested to minimize failures that could initiate an

ISLOCA. The team did not identify any significant deficiencies in the

man-machine interface that might significantly increase the probability of an

operator error initiating an ISLOCA. Nevertheless, the teani did find some ,

specific deficiencies in the availability of design calculations, check valve j

maintenance, and plant equipment labeling. The team noted that yot are

i

addressing these issues through programs that are planned or currently being

implesiented. 1
