Dear Mr. Drake:
RE:
SAN ONOFRE UNIT NO. 1 By letter dated September 26, 1977, we informed you of a limited boron dilution incident involving the contents of a spray additive tank at an operating PWR facility. In Tight of this you were asked to review potential boron dilution incidents at your facility to assure that a similar or other unreviewed method of boron dilution was not more limiting than had been previously analyzed and found acceptable.
Your response of November 20, 1978, indicates that you have reviewed potential boron dilution incidents at your facility and have determined that the FSAR analysis of this event still represents the most limiting case. Based on your response no further action regarding this generic issue is necessary.
Sincerely, Dennis L. Ziemann, Chief Operating Reactors Branch #2 Division of Operating Reactors cc:
