AFnDAVI'l' OF ROBERT P. DOU~..S ROBEJa' P. OOUGLAS, beinq first duly sworn acec:d-inq to law, c1epc~.s and states:

l..

I. am. employed by Public service Elecuic &. Gas Ccmpany as Licensin9 Manager and ~ng Znviiomnent Manager.

!o1lowinq T:r..

2.

I have su-pervised t.~e calc:tllation of the es-timated dose associated with movinq and storinq spent fuel from the unenlaJ::9ed (264.spaces)" Salem Un.it.. l: to the elllarr;cd (1l.7tl. spaces}

s~"lt. fuel pool of Salem Unit 2.

As shown in Attachment l,. hereto which is also in~~at~ he:rci.n, t.11e cose resulting !.rem*m.ovinq o~i! cask containing two fuc.l a.sscmb1ies is approxi.ma~ely 0.4 man rem.

This dose docs r.ot i.ncJ.uce the additional.dose associated wit.~ the tiansf cr oz fuel £~cm Unit 2 to Unit.l if disp¢sal is not availab1e offsite and the Unit l pool must then be enlarged.

3.

I have also* est'2blis.hed t..Jie number of spent.

fuel clements which will have to be transferred from Unit l to Unit 2 i1 the above desC%i.bed scheme is to be carried out in accordance with t.~e latest infer.nation ~ncerninq sc.~edule and nllmber of spent fuel elements to be discharged a:f ter

.i.--~*.*

e e

each cycle.

As shewn in At:tachmerit 2r which is inc:crpo:rated by* refSJ:ence hercj.n, *the number of spent fuel elements to be trans:ferJ:ed is 500...

~*hus the total man rem ~posu.re as-sociated wit.~ such a tr:msier is 0.4 ~ 250 = 100, considerably qreater than the 2-5 man rem. asacciatad wit.~ chan9inq tbe

• racka in unit l with spent fue.l elements in t.lle poo.l.

4 *.

I thuS conclude.that, ~9 o-;hcr reasons, it is pref e.rable to expand the tinit l sp.ent fuel. pool rather than shipping.the spent fuel to an cnl.ar9e1:1 Onit 2' spent f1.lel pool..
