Dear Mr. Peoples:
JANUARY 0 i l~
Recent *seismic design evaluations conducted in the.Systematic E'(aluation Program *(SEP) have indi.cated a potential saf.~ty concern relati.ve to the.
anchorag~ and support of safety related electrical equipment. It has also been observed*that non-seismic Cat~gory I a.uxiliary i~ems *(dolleys~ gas.
bottles,.etc.) may be cHslodged by an earthquake.and. damage safety *relclted~
equipment.
These *tssues were identified during site vis.its to Dresden 2,_
- Haddam Neck~ G1nna, Oyster C.reek,.'Palisades and.MillStone _1 by r:eview teams consisting of NRC representatives an_d consl.tltants. : Since op~rability ()f the. '.
subject equipment *may be"essential durfog and after a seismtc:disturbance, *..,
- we*requ~st that you ass~ss the capabnity~of.~H s~fety related*electrical.**
.equ;pment (as*well"as *non:..s~ismic CategQry*tauxiliary items) to resist seismic forces and imp 1 ement* remedi.a l *measures*, as necessary, to increase_. *
,safety margins *. Al 1. operating.i; censees. of nuclear power fac1 l i ties are
- being notified of this Bs~e by* an I&E. Information Notice (En.closure 1 ).
Within 30 days,'. you ~re requested* to develop a~ action plan for resolution --
i of -this issue and to 'sul:)mit *it for our review.
The.following* issues shoul.d be addressed:
- 1. 'oo_e$.positive an~horage exist (load carrying mechanism oth!:?r th~n frtction);
l
~
2 *. If positive anchorage exist~~ *has thf:!. anch'~~age ~ystem.been.en_gineered with* ~dequate capac1 ty; anQ. -
. 3. **w_as the anchorage fabricated.to quality standa_rds?
The results of your investigation Of" Item l should be submitted'wittiin 60...
