[ RadSafe ] Sellafield reprocessing plant 83, 000 liter pluto nium leak undetected for 9 months

[Rogers Brent]

If an accident that results in no contamination to the environment nor
overexposures to plant staff or the general public is  "Britain's worst
nuclear accident in 13 years...", then the British nuclear industry should
be commended for their superb safety record. 

Please James.  Continue to post these worst case scenarios.

Subject: AW: [ RadSafe ] Sellafield reprocessing plant 83, 000 liter
plutonium leak undetected for 9 months


Anybody who can tell me about the reputation of the "Independent on Sunday"?
The same accident was already distributed weeks ago, so what is the reason
of putting it forward again?

It seems that the reprocessing plant was constructed in such a way, that
even mayor leaks would not lead to any environmental contamination, as it
has to be. In my quick reading of the post I could not detect any facts made
public by other mass media, that not all of the liquid was contained and did
not pollute the environment. So what? The safety barriers worked, it will
cost some money to fix the leak. Again: So what? The article mentions "the
worst nuclear accident for decade", "massive radioactive discharge". Nobody
was harmed, nothing was discharged (to the environment). Again: "So what?"

In Austrian mass media we heard and read, that: 

- Sellafield is a nuclear power plant (!!!),

- That the four reactors at the site had to be shut down previously
successively because of serious safety concerns (they were shut down,
because they simply had reached or even exceeded their age of operation and
modernisation would have been to expensive, especially considering their low
energy output.

Great news! Anybody wants to compare the impact of this "worst nuclear
accident" with the death toll and victims in the Iraq and the Afghanistan
war, the death toll on the streets of anywhere in the world from traffic,
the children killed by hunger and disease all over the world?

James, I would recommend that you turn your attention to subjects really
worth it. Forget about these "news", which are only released to encrease the
sales of a newspaper and as well serve a political agenda, independent of
its truth. 

Best regards,

Franz
