“…27 The latter figure corresponds to reactor compaction of fuel to fill all the void spaces. 28 A suggested rule of thumb is that a collapse velocity in cm/s is equivalent to the corresponding insertion rate in $/s. As presented in Appendix 1, a simplified calculation of the PFBR collapse lasts for 280 microseconds.…”

This article explores the safety capabilities of the 500 MWe Prototype Fast Breeder Reactor that is under construction in India, and which is to be the first of several similar reactors that are proposed to be built over the next few decades, to withstand severe accidents. Such accidents could potentially breach the reactor containment and disperse radioactivity to the environment. The potential for such accidents results from the reactor core not being in its most reactive configuration; further, when there is a loss of the coolant, the reactivity increases rather then decreasing as in the case of water-cooled reactors. The analysis demonstrates that the official safety assessments are based on assumptions about the course of accidents that are not justifiable empirically and the safety features incorporated in the current design are not adequate to deal with the range of accidents that are possible.

India has long pursued a fast breeder program, motivated in part by the availability of only poor quality uranium resources within the country. But progress so far has been disappointing, with only one test reactor having been constructed and having a chequered operating history. The larger Prototype Fast Breeder Reactor that is being constructed has a design that compromises safety and will produce expensive electricity, but could be used as a way to convert reactor-grade plutonium to weapon-grade plutonium. Projections offered by the nuclear establishment of fast growth of breeder reactors are methodologically flawed and based on very optimistic assumptions.
