-1 MEETING' AGENDA FOR ,

DISCUSSION OF PLANT SPECIFIC DESIGN OF ACTIVE COMBUSTIBLE GAS CONTROL SYSTEM I. INTRODUCTION BY NRC STAFF II. MEETING OBJECTIVE To provide sufficient design details of the Nitrogen Injection Capability for each plant to determine if the provisions are adequate to meet the intent of 10 CFR S0.44

~

III. AIR-CAD SYSTEM /

NRC staff will provide the basis for concluding that_the syst'em should not be used for combustible gas control. "

. Represents an air source per GL' 84-09 guidence

. Potential misuse of system

. Impact of deinerting on course of the accident

'IV. LICENSING BASIS AND BWR EPG'S ,

Reconcile any conflicts between original licensing basis and Rev. 4  ;

to the EWR EFG's. ,

j

. When will CAD be used (under what system conditions)

. Is the E0P consistent with FSAR assumptions I V. PLANT SPECIFIC DESCRIPTION OF INERTING SYSTEM The objective is to identify all essential components, design conditions, instrumentation, and power supply for the normal'inerting system to  !

determine under what post LOCA conditions the system could be expected to function as a combustible gas control system. l A. System / component description All components required to operate under post LOCA conditions should  ;

be described.

Design specification (i.e. seismic, redundancy, quality group, etc) for a parameter where the component has not been designed for, such as seismic, but is expected to s!:rvive, provide the basis

. Location

s e

. Design pressure and temperature Maximum containment conditions for component operability should also be noted

. Design flow rate as a function of containment pressure B. System Instrumentation Instrumentation recessary to operate the system post LOCA should be identified. f-

. Identify each sensor, number and location -

. Location of instrument readout If outside control room, determine accessability post LOCA

_ . System use of sensor output What is sensor used for-(automatic valve operation? or not) if operator information only, indicate what type of action is anticipated (flowchange,systemshutoff,etc)

C. Operational requirements post LOCA Identify those actions that will be required to initiate system operation and those necessary for monitoring operation. For each action, identify whether it is from the control room or at a remote site.

. Instrumentation needed for startup l

. Instrumentation needed for operation

. Power supply (off site and diesel?)

D. Nitrogen capacity (onsite and time to get added supply)

E. Identification of deviations from GDC 41,42, and 43 '

l F. Modificationstoeliminatedeviationsfrom(e)

G. Operational, maintenance, and surveillance history objective is to obtain some basis for determining system availability I
