In a supplement paper to a HSE Board Paper published today, the HSE has defended their decision not to prosecute for the leak incident that occurred at Sizewell A Nuclear Power Station in January 2007.  

The HSE decided that it was more effective and efficient to use their enforcement powers to issue directions to address the underlying issues on a firm and speedy basis.  For more on the HSE board paper and its supplement follow this link. http://www.hse.gov.uk/foi/releases/nd060709.htm
