Sellafield Fined £500,000 over Olympic Pool "Leak"!

I have mentioned in previous postings that the company BNG Sellafield Limited has been fined £500,000 plus legal costs of over £67,000 following their guilty plea of breaching health and safety regulations, following a radioactive leak from a pipe at its THORP facility (Thermal Oxide Reprocessing Plant). As noted before, the leak had occurred during a period of nine months, disgorging a total volume sufficient to fill an "olympic swimming pool". The discharge consisted of nitric acid in which was dissolved 20 tonnes of uranium and 160 kilos of plutonium. Although this material was highly radioactive, it remained contained in a sealed "cell" and so no radioactive material escaped into the environment. No one was hurt. The Health and Safety Executive (HSE) brought the prosecution following the discovery of the leak in April 2005. It was alleged that Sellafield breached three conditions attached to the Sellafield license, to which the company pleaded guilty at a hearing before Whitehaven Magistrates Court on June the 8th 2006.
This latest fine is additional to the £2 million fine levied on BNG Sellafield in August by the Nuclear Decommissioning Authority over the same incident. This fine was imposed in the form of deductions from money that the Authority pays Sellafield.

After the hearing at Carlisle Crown Court, Dr. Mike Weightman, the HSE's Director of Nuclear Safety and HM Chief Inspector of Nuclear Installations, commented:

"Our extensive investigation into the events in THORP has shown that British Nuclear Group Sellafield Limited fell significantly short of the required standards for a considerable period of time before the leak was discovered. Although we stress that there is no evidence of any harm to workers or the public, the leak being contained within a stainless steel lined, heavily shielded cell, there had been a significant prolonged reduction in attention to the high standards demanded, something we are not prepared to tolerate.

"THORP was Sellafield's flagship plant and built to high standards. It must also be operated, maintained and managed to the high standards we insist on, and the public have a right to expect from the nuclear industry.

"For the wider nuclear industry, our message is clear: high standards are demanded of the nuclear industry, this means continued vigilance and close attention to maintaining all the multiple physical and administrative barriers put in place to protect people and society from highly radioactive material.

"It is not acceptable to allow any of these barriers to degrade and weaken, relying on the existence of other barriers to secure continued protection. Industry must continue to embrace high standards of design, construction, operation and maintenance and vigorously strive to maintain them at all times."

Hi Martin,

aw, who doesn't like a nice juicy "nuclear" story? They are entertaining at least! Not wishing to sway debate one way or the other, I just present the facts, so my "readers" can draw their own conclusions.

But, if you're asking, what do I really think about nuclear, O.K., here goes. I don't believe there is any immediate way to substitute total current energy entirely by renewables, if ever. That may just mean we need to buy some more time to develop them, and nuclear could help with that, or indeed it could become a major source of energy for hundreds of years, using breeder technology based on uranium or thorium. Whatever final energy mix we will end up with I think society will become less energy voracious, with localised enterprises taking centre stage.
We live in interesting times, and ideally some form of "paced" transition would eliminate an awful lot of suffering, rather than going to war over resources or doing nothing until economic "brick walls" are hit - cars abandoned by roadsides, cites left derelict, mass exodus' of populations etc., i.e. full blown Mad Max chaos. I hope that a point of resolution will be reached soon, while there is still enough slack to take up the strain.

That would be my manifesto!
