(Reference memo.Rosa to:.Kintner dated '5/1'1/78.)
~Res ense Yes.
PAL utilizes the, automatic.temperature.controller.
,However:we do not use 'the cold reference 'junction 'box with this type o',penetration.
We use chromel-alumel;penetrations

estion -85 What codes were used for subcompartment pressure.zat'ion ~alysis and 'for blowdown data for this analysis?
~Res ense COPDA was used for subcompartment pressurization, analysis.
'.Blowdown.data was generated by hand calculations..
estion 86 For 0%0 and 0-250 psig drywell pressure monitors:
a.
Is manual action needed to.provide -.iad'ication,in each 'range?
b.
'What i.s accuracy?
