A dedicated and specialised tank opening team to intervene during plant outages.
France – nuclear plants
In progress since 1987
The primary purpose of a nuclear plant outage is to proceed with the replacement of part of the fuel. To do so, the reactor’s tank must be opened, the fuel extracted, then after refuelling the tank must be closed and components put back into restart configuration.
In France there are about 50 plant outages every year, the opening/closing of tanks are on an outage’s critical path, they take place in 3×8, 7/7 shift work. Working simultaneously on several plants is a major constraint for resource management.
Being mainly equipment handling/lifting and assembly/disassembly operations linked to the reactor’s core, these operations require a high level of nuclear safety culture from those involved.
about 15 interventions per year, every year
people in the ʺtankʺ team
who intervene from site to site on all the French nuclear power plants.
an opening/closing intervention requires about 3,000 man-hours.
