The analytic results obtained from the PCT evaluations revealed that the most limiting accident was the case with a break at the Main Steamline Outside Containment. Its PCT was 1289.15 ℉, which is much below the upper temperature limit of 2200℉ set by the nuclear regulatory authority. The most limiting accident for the minimum water level measured outside the core shroud is the case with a break at the High Pressure Core Flooder Line, the minimum water level drops to 18.4 ft. For this case, even though the water level has dropped to 11.6 ft below the top of the active fuel, the reactor core was still completely covered by the two-phase water.

The deep water deposition means the deposition in the area where the water depth is larger than 30 meters, in which the major sediments are coarse sand and gravel. This kind of deposition is the relic deposition formed by the Pleistocene alluvial-lacustine deposition reworked under modern channel currents actions, and ususally the Holocene acummulation lack in the deep waters. The transitional zone deposition is the deposition between the low tidal level line and the 30 meters isobath, where the sediment types is changeable and the grain sizes are gradually coarsening from the low tidal line to the deep water area. This kind of deposition is developed by the deep water eroded sediments sorting under the transitional zone current action. The different types distributed along the isobath. The tidal flat deposition is the fine sediment deposition on the tidal flat which is flo sedimentation of the silty clay under the tidal flat dynamic action and ususally developed fluid mud on the lower tidal flat. The channel mouth deposition is the deposition in the channel mouth area. According to the sediment types, it includes sand deposition where there are coarse sediments supply and silt deposition where there are only fine sediments surpport.
