A fresh wave of industrial action to hit Sellafield.
Today saw hundreds of workers who monitor radiation levels, walk out in a dispute over pay.
With both parties - the GMB Union and management at the site - refusing to back down, more strikes are planned this week.
From Sellafield, ITV Border's Kate Walby reports.
A team from Sellafield Ltd are celebrating a million hours without an employee injuring themselves.
It is the third time the team has reached a million hours without an employee accident which would result in the person having to take a day off work.
Project manager Dan Priebe says it is a 'significant achievement'. The team have spent 12 months working on the delivery and installation of 'the largest module ever to be delivered to the Sellafield site, the massive Evaporator module'.
Dan Priebe went on to say, 'this is clear demonstration of the team’s commitment to maintaining our impressive safety standards and reflects well on the continued success of a strong safety culture throughout the year.'
Sellafield Ltd have said they 'regret' dumping five bags of low level radio active waste at a landfill site at Workington and that they 'accept responsibility' for the incident.
Today the company lost their high court appeal against a £700,000 fine imposed last year.
Lord Thomas said that Sellafield deserved very considerable credit for the guilty pleas made at the first available opportunity and the very considerable co-operation it displayed after the discovery of the failures.
In considering the appeal, the court also took into account its previous offences.
The court had regard to its turnover of £1.6 billion - or £30.7 million per week - and its annual profit of £29m - or £560,000 per week.
Lord Thomas said It was clear that viewed in the light of those financial circumstances, a fine of £700,000 after a guilty plea was a fine which reflected a case where the culpability was moderate, the actual harm in effect nil and the risk of harm very low.
Sellafield ltd has lost its appeal against fines levied against them last year.
In February, the company was fined £700,000 for sending bags of radioactive waste to a landfill site.
The bags, which contained waste such as plastic, tissues and clothing, should have been sent to a specialist facility that treats and stores low-level radioactive waste, but a number of management and operational failings led to them being sent to Lillyhall landfill site in Workington, Cumbria.
Today, the Lord Chief Justice Lord Thomas, sitting in the Court of Appeal with Mr Justice Mitting and Mrs Justice Thirlwall, said there were no grounds for criticising the level of fines imposed.
Sellafield has been fined £700,000 for sending bags of radioactive waste to a landfill site in Cumbria. The bags containing waste such as plastic, tissues and clothing were sent to Lillyhall landfill site in Workington in April 2010.
The bags should have been sent to a specialist facility. Sellafield found the error was caused by the wrong configuration of a new monitor which passed the bags as "general" waste making them exempt from strict disposal controls.
This breached the conditions of Sellafield's environmental permit and the Carriage of Dangerous Goods and Use of Transportable Pressure Equipment Regulations.
Five hundred jobs are to be created at Sellafield Ltd nuclear plant in west Cumbria.
