The Chernobyl Accident A Technical Evaluation I. INTRODUCTION On April 26, i986, the #4 reactor at the Chernobyl Nuclear Power Station suffered a severe accident. The core and much of the building were destroyed; all the noble gases and several percent of other fission products were released to the environment. The reactor design and the accident sequence, have been studied extensively since then. While a reasonable amount of information on the reactor design was publicly available, (References 1 to 6) the specific features of unit 14 design and the accident sequence, were presented by the Soviets at an International Atomic Energy Agency (IAEA) meeting in Vienna in August 1986. That report (Reference 7) is the most authoritative data available to date, and this information is now being used by all countries with a nuclear power program to examine the robustness of their plant design and operation with regard to the events at Chernobyl, and to see what lessons can be learned. In this report we present the design review done to date in Canada by AECL. From the Canadian point of view it covers: 1. relevant information on the Chernobyl design and the accident, both as presented (References 7, 8) by the Soviets at the Post-Accident Review Meeting (PARM) held in Vienna from August 25-29, 1986, and as deduced from publicly available Soviet documentation, 2. details of AECL's technical review of the CANDU PHWR (Pressurized Heavy Water Reactor) against the background of the Chernobyl accident, and 3. implications of the Chernobyl accident. Reviews of operational aspects are underway by the Canadian electrical utilities and a review by the Canadian regulatory agency (the Atomic Energy Control Board) is near completion.
