Chernobyl safety lessons for the CANDU system

Although the reactor types are very different, so that a Chernobyl-type accident is impossible in a CANDU reactor, nevertheless, CANDU designers have learned the following lessons from Chernobyl: 1) To conduct a more fundamental review of possible flux shapes in the core of CANDU reactors, and then to determine the effectiveness of each of the two shutdown systems in relation to these flux shapes; 2) To review the use of interlocks, key switches, etc.; 3) To review fire safety with special attention to any radiation hazards that may impede fire fighting
