A court case brought against Sellafield Ltd has come before a judge, after a worker was allegedly exposed to plutonium.
Sellafield attended a hearing at Carlisle Crown Court today.
The company is being prosecuted by the Office for Nuclear Regulation under the Health and Safety at Work Act.
In an incident at the nuclear plant on 5 February 2017, it's alleged that a worker was exposed to plutonium.
Sellafield Ltd is alleged to have failed to ensure the health, safety and welfare at work of all its employees, including Jonathan Greggain, "in relation to the risks arising from hand working within glove boxes."
The company entered no plea.
A three-week trial has been provisionally set for March 2019.
Before then, a "pre-trial review" hearing will be held at the crown court in November 2018 when a plea is due to be entered by Sellafield.
