NS SAVANNAH TIME-TO-MELT CALCULATION PROCEDURES

As part of a primary safety consideration for the N.S. Savannah (preventing fission product release in the vicinity of the general public), the study had two purposes: (1) to simplify the manual calculation procedures presented in Fast-4, "Time-to-Melt Data and Calculation Procedures," and (2) to recalculate the one-hour heat generation value utilizing a more realistic core heat transfer model. The simplified manual calculation procedure developed is based primarily on a combined graphical presentation of one-hour heat generation and power level data. The approach permits the one-hour heat generation value associated with a specific power level block to be obtained directly from a graph without calculation. The core heat transfer model used in this study to establish the one-hour heat generation value considers the effect of the controlling heat loss mechanism, radiation.
