CANDU и Украина Опции

[Миклован]

Прочитал Бродникова. Не понял: он про CANDU на полном серьезе выступает, или это игра для политиков?

Я так понимаю, что я тот самый русский объевший бедную обезьянку. Но как тогда будем поступать с этим:
Slightly-Enriched Uranium

Additional benefits are achieved by utilizing SEU fuel cycles in CANDU reactors. With enrichments between 0.9% and 1.2%, fuel-cycle costs are reduced by 20% to 30% relative to the natural-uranium fuel cycle, largely due to similar reductions in uranium requirements. Spent-fuel costs are reduced by up to 30%, due to higher burnups achieved with SEU (Baumgartner, 1998).

Higher fuel burnup can be traded off against higher core power using SEU. Differential refuelling rates can be used to raise the power in the outer channels of the core, flattening the radial flux distribution. This allows plant uprating without exceeding existing limits on maximum bundle or channel power.

In new CANDU plants, this strategy of flux flattening can be used to increase the nominal power output without increasing the core size. The CANDU-9 design, normally rated at 935 MWe, can be increased to about 1100 MWe, an 18% increase.

SEU can be used to tailor the reactivity coefficients of the CANDU lattice. In particular, the void-reactivity coefficient can be tailored to meet any customer’s requirements, using a combination of SEU and a strong neutron absorber in different locations within the fuel bundle.
