The status and schedule presented for the Pcol Dynanics Load Supporting Progran to define conservative loads is shown in.

The target date for connletion of this procram is July 1977. The applicants also described a follow on effort to verify loads and establish margins. This effort will be completed after July 1977.

Japanese !krk II Containnent Program Representatives of the Mark II owners group visited Japan during January 10 to 13 to discuss the Japanese Mark II containnent loads program.

The Japanese have constructed a 1/6 scale leep of a 1100 inI(e) tiark II plant. They plan to run sinqle vent (single cell) and I

multi-vent (5 coll) scale (1/G) tests to. study pool swell and steam (chugging) leads. The schedule and general descriptior.of the test is shcwn en Enclosure 3.

In addition to these tests the Japanese have been considerina conducting full scale tests to confim scaling factors. This test systca would consist of a 40'3 pie shaped sec7.ent of the Tokai-2 nucient ecuer plant with 14 Jowncocers. The large scale proqran is a government funded cro-gram which has nct been approved yet, thouqh OcVertr.icnt funds hwe been recuested.

If constructed, test are exnected to be scarted in 1978. The : ark II comers indicated they are currcntiv nacciat-ing an infomation exchance with the Japanese utilities for tha I: ark II in#omation. They expect to return to Japan in the near future for a mere detailed review cf tha tes: program.

Stean Load (Chuaninn) Procram (a)

Analytical program The obicctives of the Mark II cuners analytical procran in the short tom (mid 1977) is confir.: the conservatisn of the 4T tests boJndino loads and in the lcno tem develop a physically based realistic todel for plant unique load predictions (Enclosure 4). The schedule for this progran is shown in Erclosure S.

,(b)

Experimental Program During the December 2,1975, coeting between the staff and the fiark II owners, the fiark II owners indicated a full size experimental prograni was being considered (Sce Dec. 29, 1975 meeting Sumary by S. lliner). At this meeting the !! ark II owners indicated they had stopped further consideration of a large scale test. They proposed replacing this test with the scaled nodel Japanese tests (discussed above) and a series of scaled single cell tests at the CREAT:E Comnany dosianated the creare tests. The Japanese tests are e.<pected to show that when one coes from single vent to multi-vent the boundary steam loads will decrease.

The creare tests are expected to

• ~ T

APR 18 B77 demonstrate that there is a scalina rnlationship between the scaled models and full sizo model. The overall program is expected to demonstrate that the full size 4T single cell test has already provided the boundinq steam 1 cads.

The schedule and qeneral test information is shown in.

Scaling evaluations and the base case data are shown in Enclosure 7 and Enclosure G.

(4)

EPRI/ SRI The EPRI Phase II test program in tthich the drywell was scaled have been completed and the rcrort en the tests will be published on April 1. 1977. The report sdll be publishad in the opan literature as on EPRI report. GE is currently revic>in1 the report and will utili:c the dnta to comparc with the DFFP. todal. The evaluatien td11 be submitted in !! y either as a separate report or as part of the DFFR.

EPRI is also pitaning a singic call seclec test of the 4T test (1/10 scele). Test syst:m are currently beino desianed and the testing is c:gocted to be cc~:1ctc1 by nid-=m:er. GE will crepara a report en cerraletin7 the 4T test rasvits tc the EPP.I single co!o t

test. The rescrt is expected to be cetn10::d by the cr.d of 1977.

The ftark II osecrs stated that the EPRI tasts should ta applicable to the liark II cont:innent and they uill use these test to satisfy the staffs requirement for air and thrce dironsional pool swell test.

(5)

Supr.orcadStru'ctureLoads The analytical pronran has been funded. There is a hold point in the analytical program where a decision will be nade as to whether further testing will be required. The program description is shown in Enclosure 9 and the status of the progran is shonn in 0.

(6)

Honticello Tests The sumnary of the portion of the meeting coverin9 the monticello tests is covered in a reeting sun?.ary from T.fi.S. to Gus C. Lainus dated Jurch 3,1977. The meeting sum =ary is enclosed as Enclosure 11.

e

r

. APR 181977 Suninary We stated that a number of inportant questions related to the confirma-tion of DFFR !! ark II nool dynamic loads remain unanswered at this time.

We stated further, that the current Mark II owners group schedule for resolution of these questions by July 1977 was very optinistic. Our co nents on problem arcas which could inpact on the Park II pool dynamic load confirmations schedule included the following:

1.

Steam Loads Ue indicated that the full scale culti-vent steam tests representa-tive of a !! ark II containment should be nerfon ed to confirm chuqging and condensation loads. !!c'e:cver as outlined above the f! ark II o;;ners aroup proposed an acaroach which censists of utilizing the 71/G scale multi-vent.leanese tests to detornine multi-vent stea : loads and cond.ectinq a number of sincle vent tests of various scala, to establish the scalina relationship bet::cen the 1/6 scale ruiti-vent aodel tests and a full size plant. Ua stated that bas 0d on the inforastion prucntad.'.t this F.eetinq 'KO had reservations tn:t this approach tmuld be successful.

Consider-abic additior,a1 inferreation renarding this progran was needed to establish the feasibility of the approach.

2.

FjufdStructureIn_tcracticn The progra"1 to r: solve this concern for LOCA and ST! stean leads decs not appear adequate. Additional infornation will be required.

3.

Poo_1 Svell (3D gd Air Tests)_

L'e stated that the owners qroun should discuss at the next meeting how they propose to use the EPP.I test data to satisfy our request for pcol swell related 3 dinensicnal and air tests.

4.

Submrced Structures Oran_ Loads We expressed concern that a strictly analytical approach lacking an adequate experinental data base would bo inadequate to define sub-mer0cd structuro drag loads.

5.

Next Meetino Acenda To provida the infornation we require we suqqcsted that at 1 cast the following infonnation should be included in the naeting agenda:
