Mode of self-sufficiency by the uranium-233 for heavy-water power reactor of CANDU type

Possibility of effective using thorium-uranium fuel cycle in conditions of the CANDU type heavy water power reactor is considered. Calculating investigation into two regimes of reactor operation is conducted. Feasibility of accumulation of the necessary 233U amount at the first stage of exploitation at the expense of burning of certain amount of energetic plutonium or enriched uranium is demonstrated. It is shown that using only accumulated 233U provides long-term operation of high efficiency power reactor in the regime of self-assurance by fuel
