Time-to-melt data and calculation procedures for the N.S. Savannah are presented. The time-to-melt criterion is applicable when the vessel is moored. Basic considerations of the problem are outlined, and decay heat curves and calculational methods are given. It is emphasized that with tugs maintained on call such that they can arrive at the vessel at least one-half hour before first fuel-clad melting, then starting removal of the vessel to the remote anchorage, there should be little, if any activity release in the berth area. There should also be little activitiy release to the atmosphere while the towboats are moving the vessel. Figures are included on: decay heat rate as a function of irradiation time and shutdown time; integrated heat as a function of irradiation time and shutdown time; and time-to-melt vs. heat release in the first hour after LOCA.
