E Response to Deviation 413/84-36-04 Corrective Actions In Duke's letter of. April '14, 1983 to. the NRC/NRR, it' was stated that in. each Reactor Building there are two (2) 150 lb. hydrogen cylinders

?

and associated piping which provides a gas blanket for Reactor Coolant Pump drain tanks.

.The subject cylinders have been relocated to the hydrogen. shed in the plant yard (Ref: letter of clarification dated April-25, 1984.).

An' excess flow valve will be provided in the discharge piping at the' hydrogen shed.

flechanical systems will review pipe routing to assure that if non-seismic pipe were to fail, concentration of hydro-gen in the area would be below 2%.

This complies with the Standard Review Plan.

Also, a pressure test of this QA Condition 3 piping does

. not require QA inspection.

Status Full compliance to be achieved prior to Fuel Load.
