The last remaining body has been found by investigators at the Didcot Power Station wreckage, more than six months after part of the building collapsed.
Thames Valley Police said they believe the body to be that of John Shaw, 61, who has been missing at the site since the disaster in February. His family has been informed.
He is the last of the four men to be found following the collapse of the boiler house.
Ken Cresswell, 57, from Rotherham in South Yorkshire, was discovered in the wreckage on Wednesday.
Michael Collings was found soon after the collapse of the building, while Christopher Huxtable was located on August 31.
A police spokesman said: "The contractors have paused the removal of debris so that specialists from Thames Valley Police, Oxfordshire Fire and Rescue Service urban search and rescue and the South Central Ambulance Service hazardous area response team (Hart), can enter the site.
"The safe recovery of the body will take place and the disaster victim identification process will commence.
"The person has not yet been formally identified and this will be a matter for the coroner, although it is believed to be John Shaw.
"Our thoughts remain with the families and friends of all four men and we would ask that their privacy is respected during this incredibly difficult time."
In July, site owner RWE Npower carried out a controlled explosive demolition at the decommissioned site in an effort to locate Shaw, from Rotherham, and his colleagues.
The firm said experts were working seven days a week, 12 hours a day, in an effort to recover the bodies.
