Workers at the Sellafield site have called off strike plans.
Construction workers at the West Cumbrian nuclear site, who work for around 31 sub-contractors, were due to start industrial action on Monday.
Members of the Unite union were planning to walk out until Sunday June 21.
Union members are demanding site-specific allowances, which they claim are paid at other nuclear sites across the country.
They first began industrial action in September last year. It concluded at the end of January. Workers did not strike from December 22 to January 2.
The workers, who are employed by sub-contracting firms at the nuclear complex, took part in a second ballot by Unite this year.
Workers voted in favour of taking further industrial action on March 19.
The union confirmed that its 1,720 members – who work for 31 firms – were reballoted.
The results of the most recent ballot show that there were 1,140 votes cast – around 66 per cent of those entitled to vote – and no ballot papers were spoiled.
681 voted in favour of continuing industrial action and 459 voted against.
A Unite spokesman said: “”Planned industrial action at the Sellafield site has been postponed to allow meaningful discussions with the employers to take place.”
The union, which has not responded to Cumbria Crack since the ballot results were revealed, issued a statement yesterday, Tuesday June 9.
It claimed then that the employer group had failed to engage in discussions.
Unite regional officer Ryan Armstrong added: “Unite remains willing to enter into meaningful negotiations and the site negotiating team continues to work tirelessly to find a resolution.
“We have requested discussions so every opportunity to avoid industrial action can be explored. Our members simply want fair recognition for the work they undertake.”
Cumbria police were notified that strike action was taking place, but it is understood that officers have been stood down.
Yesterday, a Sellafield Ltd spokesman said: “The industrial action is the result of a pay dispute between some Unite union members and their employers.
“As the people involved are not employed by Sellafield Ltd this is not a dispute that we can resolve.
“Our priority, as always, is to maintain the safety and security of the Sellafield site.”
