RE: RADSAFE digest 3104
There're some recent (yesterday?) Japanese news articles on the criticality
patient at the bottom of this set of e-mails. FYI.

> NEW DELHI, April 18 (Reuters) - Indian lawmakers said in a report on
> Tuesday that a government programme to generate 20,000 megawatts of
> nuclear power in 20 years time was too ambitious and must be
> reviewed.
>
> ``This appears to be an over-ambitious and unrealistic programme

>
> India's ten civilian nuclear power stations produce 1,840 megawatts
> of power, which is barely 2 percent of the country's total power
> generation.
>
> The atomic energy department has set a target of lifting nuclear
> power capacity to 20,000 megawatts by 2020, but the parliamentary
> committee felt targets must be practical.
>
> ``The Committee therefore feel that it would be better if the
> department draw up a plan fixing short and achievable targets to be
> achieved in the short time-frames and to make concerted efforts to
> achieve those targets which could ultimately lead to their target of
> 20,000 megawatts,'' the report presented to the lower house of
> parliament said.
>
> India's forty-year civilian nuclear programme has been dogged by lack

>
> In May 1998, India carried out a series of nuclear explosions
> triggering a slew of economic and technological sanctions by the
> United States.
>
> The parliamentary committee urged the government to consider building
> nuclear power stations in the eastern and northeastern parts of the
> country. Currently, the ten power stations are located in the
> southern, western and northern regions.

> ``They should make a detailed and in-depth study of various aspects
