$h Chatrsan, Nuclear Regulatory Commission 1717 H St. NW Washington, D.C. 20055 Dear Sir; I question the safety design o f the Brown's Ferry Nuclear P1, ant in the following arecs.

Although I think some calculations about the drop-ping of a spent fuel bundle and breaka'ge of came were made, I an concerned about the possibility of a plane crashing accidently or by terrorists, into the secondary containment with spent fuel outside the reactor.

I think the dropped fuel accident assumes that the secondary contain=ent remains intact.

What if the plane ca=c through the roof into the reactor core or into the spent fuel pool?

I don't think the FSAR included this possibility or the possibility of a plane crash at the intake structure.

Such a crash could possibly cut off all sources of cooling water with the g

exception of the condensate storage tanks.

Of course a fire in the intake tunnel or building ci;;ht possibly result in the dame cutoff.

With all the redundancy and seperatione of systems, I still don't understand why all the intake water pu=p wiring for all 3 units was routed through the same cotson tunnel.

I know that temporary wiring and pumps could i:e installed on such e an occasion.

Nihat I do not know is whether the design pressure of the pri=ary containment is high enough to contain the pressure until such temporary =easures were effected.

Do you.know?

Thank You, Y
