Dear Dr. Seaborg:
i At the Cemission's request the Adviscry Co==ittee en Beactor Safe-
~^ ~
E guards has frequently given assistance in develeping ani reviewin6 I
site criteria, which are intended to prcrride g"Mws to applicants
[
ani reactor designers.
'Je have, during the rast two years, sent h
several letters of advice en this mtter. h ae are referenced r
liner below. At an Enydental Subcoc=ittee }ieeting on Nove=ber 29, and at the thirty-eighth meeting at the ACRS, we conducted cur est 7
recent reviews of ciedificatinns to these criteria. h preposed revisions were innde in the light of coc=ients received after the
[
.mblication of the guides in the Federal Register on February 11, 1951.
[k It is our belief that the identification cf these criteria as Euides
/'
rather than as regulations indicates the correct interpretatien of 4
the precent state of reactor design, sterials, ami o;erating expe-
<cf.'
rience. We strongly support the deletion of the Appendix calcula-d tions in the guides and the issuance, instead, of a Technical hg Infor=ation Docu:sent which shows an spplicent hev to develop values for er.clusien distance, lev population tene, and population center
[
J distance. 'lhe Technical Informtien Doctnect can be up-dated at E
intervals as exIerience and other data varrant.
The salient feature of these guides is the presentation et vbole body and thyroid er;osures which my be used fer the purposes of
{
design and cite selection within the centext cf the criteria. 'Ibe i
publication of such values represents a policy decision on the part of the Coc=ission which cakes these criteria meaningful.

2 We reco.gii.e that these rjides do have some arbitrary factors in 5
them far the purpose o; dictance-dose calculation. For the present

tir s the population center distance values p:tnride what we believe 4
from the standpoint of design and site selection.

'Jhese guides also provide for the first time an approach for considera-
' 3 tion of rcre than ene reactor at a given location. 'lhey also stress
(
5 the fact that they rere developed for stationary power and testing 4
- reactors, T
2 It is clear frc:n these guides, that reactor safety must still be f
baoed on judcacnt.
JiiM ev nt remsins necesssry for a.ssessin6 the L
value of engineering cafeguards, quality of materials, and coc:petence C
of the reactor designer and opemtor.
l It ie the opinion of the ACR3 that the revised criteria vill be useful to the nuclear industry in ident$.W practising locations and other conditions invo29ed in site celection. 'These guides should be considered an flexible and subject to revirion at stch intervals as experience in power and testing reactors regaires.
