QUAL 2-10-2 SDR No. 198 Gentlemen:
This letter is to advise you that the corrective actions described in the reference letter have been completed except for the following:
a)
The corrected CADD P&lDs and QADs have been issued for use from Bechtel Western Power Corporation.
The third level PECo Engineering review, however, is approxlinately 70% complete for the P&lDs end just underway for the QADs. We expect that these reviews will be complete by 9/1/87 and 10/1/87 for the P&lDs and QADs respectively.
b)
The PECo-QA findings addressing potential recurrence of similar problems during possible future CADD conversion projects have not been fully resolved. We expect that these findings will be closed
{
by 10/1/87.
If further information is required, please do not hesitate to contact us.
