o Iten 2 For each piece of identified equipment, provide the performance history associatcd with its usage. This should include the cause of any failures or malfunctions and the frequency of such events.
.usranse Tha installation dates and performance history for each piece of equipren identified in Table 1 is provided below:
3 rcrns Ferrt-unit 1 - PQC numbers LL321 thrcu;h LLS24, LLS33.
I LL337, LL833, LL327, LL843, LL844, LLS67, LLS71, LLS72, LLSS3, LL900, PP153, PP161, PPl79, 2639, and Z644 are being fabricated at this time and will be installed in the spring of 1981. No
,erferrance data is available.
I Eroens Ferry unit 2 - PQC nunbers FF326, DD251, and V644 were i
insta11cc in the spring of 1978. Since then, a visual exaaination was performed during tha spring of 1979 outage and l no indications of calfunctions or failures were found.
3rcuns ?erri unit 3 - ?QC number LLS63 has never been, nor are thara any plans for it to be installed; therefora, the equip-rent has no performance history. PQC numbers FF120, EE359, l
FF093, and DD369 were installed in the fall of 1979. Since then, the unit has been online and no opportunity for visual chamination has been presented. However, operations experience 6
has indicated acceptable performance of the identified equipment.
I, We conclude that the performance history of the installed final fix spargers I
at Browns Ferry Nuclear Plant units 2 and 3, which were mainly manufactured at Marvin Engineering Company, have an acceptable performance history to date.
Item 3 Provide information on the supplier's and receiver's QA/QC program in cffect at the time of purchase. This information should be discussed in j
tcres of it providing suff'cient bases for judging that the integrity of j
the equipment is sufficient to permit plant operation during normal __.___.___ __ _
l and accident conditions.
