SUBJECT:
UPDATING BWR STANDARD TECHf1ICAL SPECIFICATI0fiS Off WATER CHEF 4ISTRY In reviewing the Technical Specifications proposed for LaSalle County Station, we found discrepancies between the Standard Technical Specifica-tions for General Electric Boiling Water Reactors, NUREG-0123, revision 1 (April 1, 1978) and Regulatory. Guide 1.56, " Maintenance of. Water Purity in Boiling Water Reactors", revision 1 (July 1978). We have updated Section 3.4.4, Chemistry of Reactor Coolant System, of the Standard Tech-nical Specifications to conform to the regulatory positions in Regulatory Guide 1.56, revision 1.
Attached is a marked-up copy of the updated Technical Specifications which resulted from our discussion with R. Bottimore.
We request that the updated Technical Specifications be incorporated into the next revision of NUREG-0123.
