-==i Gray file Gentlemen:

E==

By letter dated May 1,1978, you requested, pursuant to Regulatory Guide 8.15, Section C.6 MRC approval of the use of a double-bibbed plastic hood by personnel at Rancho Seco Nuclear Power Station.

.. jg This is to advise you that the approval provision of Regulatory Guide

k.....

has been approved under the schedules in 30 CFR Part 11 or where there

~ ~~.1 8.15, Section C.6 applies only when no equipment of a particular type is no existing. schedule for approval of such equipment.

In the present instance, since there are already a number of approved supplied air

- ff.;

hoods (e.g., see LA-MUREG-6612-PS, " Supplied Air Hood," dated

==$

4~

Decerber 1976 (also' carries report number UC-41)), we conclude that

===R Section C.6 of-Regulatory Guide 8.15 does not provide a basis for i... ;...,

.Comission review of the acceptability of an additional supplied air-tiEin chood in this instance. Although you state that some equipcent already 055l approved ~under 30 CFR Part 11 is inferior to the double-bibbed hood -

. f.]

under conditions'of unusual ' operations (e.g., steam generator work),

is==a it would be prudent for you to select another approved hood from the f= '

listing -in the afdrementioned report that' will be acceptable for the i:

E==e Job.-

[.:-1..

It is noted that if the Comission were to undertake a review of the

[_.

acceptability of an air-supplied hood, such review would require more F ::

1 than the. testing. described in the report TREE-1214.. For example, I

the Quality Control program of the respiratory protection device P=

f!@@

manufacturer;would also require review to detemine its effectiveness' '

}[=s

_in. insuring. quality through the manufacturing cycle.
