The risk figures for a severe nuclear accident assuming 1000 reactors in operation given in the News and Comment briefing "Using experience to calculate nuclear risk" (23 July, p. 338) did not accurately reflect the probabilities cited in the NRC report. An accurate rendition is as follows: With 74 reactors in operation (the present number) and if the lower risk rate (0.0017 per year) is used, a severe accident could be expected on the average of once every 8 years.
