- has becore fashionable nowadays for every self-a :cinted exter: tc ex;ress nis opinion icou: Wr.5 : snould be done to avoid an iteration "7
- f Three "iie Island.
I am 'sure the ACP.S will F-ctSTtio-., ED TO n, r.,S.M/%i nake its c0llective views kno'.en to you in due ea p '-
u' a me.
. war.:ed c make some points infer. ally
- hat migh be lost in the maze of paper you ara receiving.
The first is that the development of a usable and readily accessible set of information to
~
- ne ::ntrol rocm operator is something that
- an be done without significant capital
'nvestment and could imorove the safety pos-
- ure of nuclear : wer plants very quickly, he -hings I have in mind are.
Good one-line diagrams, possibly in iso-r.e:ric form, t:,a: onysically identify the rela-ive location of im ortant pieces of ha d..-a re.
5/7 - To EDO for signature of the Chairman.

M. Hendrie 3
May 3,1979 about the ccerator's diagnostic capability.
he second coint is that operators need a
- etter understanding of thermodynamic respc1se by these systems thrcugh some other means than observing the actions on simulators.
The
'est cbvicus need is to make sure that every
- erato
.nderstands the rela:icnship between
- " essure, tem:erature, ar.d ? nase 90uilibria,
rut they also snculd understand heat transfer
- naracteristics as a function Cf Velocity,
- iuic sta e, and Ohysical configuration of
,s a: transfer surfaces.
Again, these are liustra:ive and tney neec scme considered
- nougn by soecialists in operator training.
rinally, it is difficult for me, as an indivicual, to understand where the NRC Itaff, the Licensees, the architect-engineering
- irms, and the nuclear steam supoly vendors are ccr. centra ing their attention.
I think "t would be useful to everyone if there were i ccm;ie:E se: Of tasks identified so that one
- culd see a".a: the Industry, the Regulators and their Advisors are trying 20 acccmplish.
- c me, i; iccks like the activities are Traceedin; r.elter-skeiter withcut much rhy,e reascr :; 'icensees, EPRI, EEI, NRC and
