PROPOSED AGENDA POR NRC/ WESTINGHOUSE MEETING ON AP600 WA111R HAMMER.

I Westinghouse Presentations:

I.

Overview of the Westinghouse approach to the weser hammer issue.

j Water hammer potential exist, AP600 will be reviewed against screening criteria.

II.

Evaluation of OSU noise events.

Evaluation of the design transient SB18 data. Detailed evaluation of the processes seen during 3

the poise event. Discussion of facility test data taken at 0.5 HZ, aad fast response pressure probes at 8 kHZ.

I Discussion of condensation events observed during OSU testing. Discussion of event types versus type of transant being tested y

i 1

NRC Presentations:

i i

III.

Discussion of observations from the OSU test facility.

Discusion should be specific to the abservation of condensation events (or noise events) i supported by data.

l W.

Discussion of observations from other test facilities, Discussion should be specific to observation of condensation events, supported by data which i

describes the physical processes in the facility at the time of the events, 2

j i

Joint Discussion Issues:

f V.

Freeflowing discussion of NRC and Westinghouse personnel. The objectives should be to try to shed light on the observations, and determme if possible if these events are specific to the l

test facility or are they possible in the AP600.

VI.

Derme the water hammer issue (s) for AP600.

5.

VII.

Develop a consensus on the approach to be followed in the resolution of the water hammer issue.
