3ear Nr. Richard DiYou g:-

/

I am currently involved in the Diablo Canyon Review effort now in progr'ess.: I must say that this is the worst nuclear power plant that I have ever worked-on.

and it is not SAFE.- I was hoping with the'introduction of Bechtel that a complete re-analysis of Unit 1 would be done.

Alas this is not to be.

The PGLE management/,

engineers only correct the mistakes that are found accidentially or are forced down their throats. If the error is an generic one., they will not review. everything but just what caused the error and they will only correct;,:.-

that one mistake.

The lateat review is for-hosgri only -'-.':-.'--.".,'

but the real danger. is that:

1) The thermal/deadweight analysis does not match

, the seimic or current. field support configuration Systems are failing when corrected.

h

2) The so-'called -'As-Built"~i~e "support-dravriegs-"

're.not as-built but instead are the accumulation ~::,"-

of 'all the changes to the support drawing over the

'.'ast.13 years The support have not 'been walked -"---;.-..'.

. I 'only ask that you have R. 2

review the thermaI/Deadweight analysis as well as the'osgri they are now. doing.

This will confirm what.I have--.".';:-

said. If action is not taken, I may be.force to seek a public hearing" on this. 'I am pro-nuclear but.invalid analysis andincompetence must not be igored. This paint in my opinion is bad from the analysis to the supports.

P Thank you for your. time.
