The body recovered at Didcot Power Station last week has been formally identified as 34-year-old Chris Huxtable from Swansea.
Mr Huxtable is the first of three missing Coleman & Co workers to be located and recovered from the rubble of the collapsed boiler house.
His body was found on Wednesday before being recovered in the early hours of Thursday morning.
In a statement, Thames Valley Police said: “[Mr Huxtable’s] family has been informed and are being supported by specially trained officers. Our thoughts are with his family at this time.
“A joint Thames Valley Police and Health Safety Executive investigation is ongoing to establish the circumstances of his death.”
Mayor of Didcot Steve Connel told the Oxford Mail: “I think for Chris’s family it’s a huge thing. It means they are finally able to properly begin the grieving process and move forward.
“However, my heart goes out to to Ken and John’s family. I can’t imagine what they went through when they were told it wasn’t their loved one that had been found.
“We are happy in Didcot but also quite sombre.”
The search operation being carried out by Brown and Mason has resumed.
The two remaining missing men are Ken Cresswell, 57, and John Shaw, 61, both from Rotherham.
Coleman & Co employee Michael Collings was also killed in the collapse on 23 February.
Coleman & Co said in a statement: “Our thoughts and prayers are with all the families at this time and we remain committed to supporting the families in any way we can.”
