Marshall to H. R. Denton.

Dear Mr. Denton:

In response to an PER telephonic request from Mr. Bournia and Mr.

Shemansky,. the following information is transmitted to supplement the

reference data on conformance to 10 CFR 50.49(i).

The table in Attachment A has been revised as follows: A letter entry in the table indicates the paragraph on the previously submitted Component Application Statements which addresses the specific 10 CFR 50.49(1) considerations'. For example, the Limitorque operator _for valve 2E22-F012 l complies with 10 CFR 50.49(1) (5) per paragraphs'(b) and (d) on page M.5-2.79a~of the Component Application Statement. The absence of entries for Gubparagraphs (1) through (4) of 59.49(i) means'that these provisions do not apply as determined'by the System Safety' Analysis referenced in the opening Jparagraph of that page. The basic reference document QUAD l-81-852 Volume I Section=2 on methodology and Section 6, which describes the Component ~

. Application Statements,'provides additional details to clarify the referenced entries.

._ . Please note that,the'LaSalle JIO is a " top down" effects analysis

. which; delineates the equipment needed for safety functions during limiting

~

! accidents that create HARSH environments. From this effects analysis, the fprimary functional pathways lthrough the six required safety gates have been

[ identified.' ' Alternate. safety pathways through the same safety gates were

alsol identified. ; Equipment which performed these safety functions was thus

- : determined. EPlant arrangement at LaSalle incorporated provisions to maintain x

e - the sfunctional1 independence of these pathways. That is why the entries 10 t _.A',

LCFR;50.49(1):(1)'and'(5) are.so; prominent in this conformance appraisal.

_ . . . , Equipment upgrade or replacement has-been the primary method to

obtain qualified equipment at LaSalle.
Equipment upgrades have involved ,

'three torfour years of. testing. Full qualification of those items designated

-funder50.49(i):(2)is1expectedbyNovember 30, 1985.

Y .

.;Regarding the Klockner Moeller MCC, the current test involves '

generic qualification'of forty-four-subparts: motor starters, control and A- Radiation exposure. tests are  !

g_overloadrelays,'contactorsandtransformers. scheduled:for this month. -Thermal ag 1mid-July, and-DBA exposure in mid-August. The September 1985 completion date

- A -includesLsoms contingency-for minor delays.' Prior material analysesLand

earlier test experience at Wyle Laboratories: indicate a high probability of

~ -

'~
