- program, and identification of the generic and plant unique efforts required to complete the program.
In addition, three tasks were discussed in greater detail; these included:
Load Case'10, the extended 4T condensation oscillation tests and the Mark II program efforts to monitor related suppression system tests conducted outside the !)ark II owners" supporting

Introduction and Pro ram Histor Ct I
R Hr-Hedgecock, Chairssan of the Mark II Owner's Group presented an overview of the hark II owners supporting program including identification of the dom stic remember utilities, objectives, organization, and identification of program changes in the past year.
He also discussed the role of plant unique programs versus the generic HarL II program.

e.- Q e
gUG "1 1979 on the grounds that this load combination is non-mechanistic.
In addition, the probability for the spurious actuation of a single SRV is very small..
The results of a study for a BWR-5 plant to consider the'otential for the mechanistic actuation of an SRV following a DBA was presented by General Electric for a -spectrum of breaks The staff-requested docu-mentation of this study along with the results of a similar stuQ for.".;.
~
"=- *a BMR-4 design-'rjuments were presented relating'to the low probabil)ty,'. ~':."-.
of this load. combination. resulting from'spurious SRV actuation.'he staff requested that these arguments be documented along with the'mechanistic stu4'-
~ The staff stated. that the arguments presented appeared a reasonable basis foi providing relief from our requirement that this load case be considered in the evaluation of piping systems.

Extended 4T CO Tests-4
---, Hr. Davis "of"-General Electric,presented a status report for the extended 4T condensation oscillation tests.
I This presentation'included a description of the instrumentation, test
=- -matrix, pr'oposed-data reduc'tion, proposed data interpretation, construction status and p'rogram-schedule.
The staff expressed a concern related.to.
the consideration given to vent mass fIux and ait content in establishing the test matrix.
The staff's concern relates to the relatively high CO loads encountered in the FSTF tests during the high nass flux test.
The Hark II owners agreed to provide the staff with supporting information--.
used 'by the owners to establish the test matrix, The Mark II owners
- requested an accelerated review of-this information by the staff and our
~'onsultants to. avoid unnecessary delays in the test schedule.

Horld Test Monitorin Pro ram I
Hr..Davis"':of;General-Zlectric provided a status report of the, Mark II.
mine& program "to'monitor "related pres'sure suppression LOCA and SRV'ests conducted -outside the. Mark 'II program.. This presentation included identification.of the sources contacted,
.the type of-information'-received and identification of site visits conducted.
