' Subject Oyster Creek Nuclear Generating. Station (OCNGS)
- i Docket No. 50-219 Detailed Control Room Design Review The OCNGS Emergency Operating Procedures (EOPs) require the use of the Control Rod Drive (CRD). system as a make-up source to the reactor pressure vessel.
While in this mode of operation, the operators are cautioned not to exceed a CRD pump flow -of 150 gpm in. order to -avoid pump runout and trip.
i By letter dated July 8,1988,' GPUN identified a Human Engineering Deficiency (HED 3) 'in that.the CRD flow meters do not indicate the range of. CRD - flow required by.the OCNGS EOPs.
The. identified resolution of the deficiency.was to
.rerange.the flow' transmitters and indicators during the 13R outage.- Further review has shown this to be inef fective for all system configurations and, as
'such,. the flow transmitters and indicators will not be reranged. Monitoring of.
'l the CRD pump. approach to runout will be accomplished by the use of local.CRD pump discharge pressure indicators to be installed in 13R.~
If there are any questions,- please contact M. W. Laggart at (201) 316-7968.
