j In Reference "A", Boston Edison Company (BECo) committed to complete a modification during refueling outage 12 to replace the residual heat removal spray flow indicators and associated instrumentation with state of the art equipment to lower the instrument uncertainty to be in compliance with R.G.1.105 (Violation No, l.C.4).
