Additive borating system for nuclear reactor plant i.e. pressurized water reactor, has borated coolant supplies releasable and usable by additive pipeline arrangements and borating pumps of pipeline network

摘要

The system has a supplementary pipeline system including additive borating pumps (7-10) i.e. piston pumps, for conveying borated coolant. A pressure reservoir (1), flood containers (2, 3) and/or a flood basin are in cooperation with a nuclear emergency cooling- and residual heat removal system of a nuclear system. Mounted borated coolant supplies are releasable and usable by additive pipeline arrangements (4, 4a, 4b, 6, 6a, 6b) and the borating pumps of a pipeline network. The reservoir, the containers and/or the flood basin are arranged in two strands of the heat removal system.
