Members of Mark II Owners Group
SUBJECT:
MEETING HITM MARK II OWNERS GROUP TO DISCUSS INTERMEDIATE PLANT PROGRAM TASKS (MARCH 21, 1979)
(~mezz.P ~~/
~Bk d
The purpose of this meeting was to discuss the status of several. of the Mark II Owners'ntermediate Program Tasks.
This included:
an indepth preview of several new tasks (i.e., the condensation oscillation test task and the Bechtel improved chug 'load definition task); preliminary observations from the ongoing CREARE multivent subscale steam tests; and preliminary observations from the completed in-plant CAORSO SRV quencher tests.
An attendance list and a copy of the meeting handouts are enclosed.
~Summar Several new tasks, were recently identified as a part of the Mark II owners supporting program.
In addition significant progress was made in several existing tasks in the supporting program.
A summary of the status report provided to the staff by the Mark II owners relative to these programs is provided below.
1.
Task A.17,'Condensation'Oscillation
'Test Pro ram
. The Mark II owners proposed additional full scale steam tests in the 4T facility at the February 13-14, 1979 Mark II owners meeting with the staff.
These new, tests are directed towards obtaining a better understanding of LOCA related condensation oscillations in the downcomers.
Modifications in the full scale test facility vent length will allow a more conclusive assessment of vent length effects than is possible in subsca'le tests.
The pur pose of this presentation
Mark II Owners Group APR 13 lying was to provide the staff with a description of the proposed test including:
objectives, instrumentation, test matrix, and parameter control.
In addition a description of the preliminary facility design was provided.
The original 4T facility included a non-prototypical vent.
In the new tests, the facility will be modified so that vent length would be prototypical of the Nark II plants.
In addition, provisions will be made to incorporate a removable vent riser and jet deflector in the drywell.
The original 4T instrumentation system has been expanded to allow an indepth study of the steam condensation phenomena in the vent and at the pool boundary.
New measur ement techniques will be employed in these tests to enable accurate determination of vent air content.
These tests, which are still in the planning stages, are scheduled for completion in the second quarter of 1980 with reports to be issued in the fourth quar ter of 1980.
The tests are considered to be confirmatory by the Nark II owners.
They wi'll provide information to establish the conservative nature of the current lead plant steam loads.
The Nark II owners stated that the thrust of these tests was to study, condensation oscillation loads at the pool boundary.
Ho attention is to be given, in these tests, to the further study of lateral loads on the vents.
2.
Task A. 11 Nultivent Subscale Testin Representatives of the Nark II Owners Group and Creare, Inc. reported on the preliminary results of Phase I of the 1/10 scale multivent tests.
These tests consist of steam tests conducted with 1, 3 and 7 vents.
These tests were directed at multivent phasing investigations.
A presentation was made of the types of phasing data and studies of the 3 vent tests that are being conducted.
Preliminary results from these tests confirm that the use of a lead plant multivent multiplier of one is conservative.
In addition, results of the tests show a reduction in the multivent multiplier with increasing number of vents.
Single vents tests conducted by Creare since November 1978 were also discussed.
These tests were conducted to address questions relative to the repeatabi lity of earlier single vent tests under conditions of varying vent air content.
Improved repeatability was observed in these most recent tests.
