NNECO has been informed by the fuel vendor in Reference (2) that the small break LOCA model applicable to Combustion Engineering nuclear steam supply systems will be submitted to the Staff by March 15, 1983. Plant specific small break LOCA analyses utilizing the revised models are scheduled to be complete within one year af ter Staff approval of the model as specified in item II.K.3.31 ioVl 8209100117 820902 PDR ADOCK 05000336 P PDR
