Updated: New incident report added – Soil sampling process
Below you will find details of operational issues and events.
We closely monitor and audit activities on the Sellafield site.
It was identified due to the diligence of this auditing process that some metallic waste which potentially contained asbestos had been sent to a facility not permitted to handle asbestos.
All of the waste concerned has undergone thorough radiological checks and does not contain any nuclear material.
We are working with the operator of this facility to understand what, if any, consequences arose as a result of the handling of this waste.
This investigation is ongoing and all of the relevant regulatory authorities have been informed.
During routine sampling and testing of small amounts of soil on the Sellafield site to ensure its suitability for reuse, the relevant project backfilled the excavated area prior to receiving confirmation that it was suitable for backfill.
The soil in the area where the sampling took place is considered low risk and there are no safety or environmental consequences.
An investigation has been carried out, and we are considering any actions required to address the findings.
During routine maintenance work on the ventilation system of one of Sellafield Ltd’s intermediate level waste stores, an extract damper (valve) was left open resulting in air from the store bypassing the High Efficiency Particulate Air filters.
Once it was identified, the damper was returned to its correct position. The air leaving the store is continuously monitored and there were no safety impactions during that time.
Sellafield Ltd is carrying out an investigation, and will take action to address the findings.
Due to freezing temperatures at the beginning of March, there was a water leak from a water pipe on an elevated pipebridge on the Sellafield site.
As a result, water ran into nearby pipe trenches below ground level.
The volume of water resulted in a discharge through a number of non-routine routes, including a leakage to ground. The water carried very low concentrations of radioactive contamination.
The water was removed and safely disposed of via our robust processes. A management investigation has been carried out to understand the root cause and identify learning from the event.
There were no safety implications for the workforce or the general public.
The event carries a Nuclear International Event Scale Level 1 rating (an anomaly) based on ‘minor problems with safety components with significant defence in depth remaining.’
During routine sampling work in a product finishing line facility at Sellafield, a small number of contaminated waste items fell through the end of an unsealed bag causing the waste to fall to the floor.
The operator handling the samples was wearing the correct personal protective equipment, and the individual suffered no ill effects. Also, the contamination was contained within the immediate work area.
The material was immediately made safe and the area subsequently cleared of any contamination.
An investigation has been carried out, and we are considering any actions required to address the findings.
The event carries an International Nuclear Event Scale Level 1 rating (an anomaly) based on ‘minor problems with safety components with significant defence in depth remaining.’
During routine sampling work in a Sellafield drum filling area, a bottle containing uranium trioxide powder accidentally fell to the floor causing approximately 100-150g to spill out.
The operator handling the samples was wearing the correct personal protective equipment and the correct safety procedures were followed.
There was no personal contamination or ingestion by the operator and the contamination was contained in the immediate work area. An investigation has been carried out, and we are now considering the actions required to address the findings.
The event has been rated 0 (anomaly) on the International Nuclear Events Scale.
Level 1 represents the lowest severity, known as ‘anomaly’, rising to Level 7: ‘major incident’.
An employee was contaminated during operations in one of our analytical laboratories at Sellafield.
This was identified following routine internal dosimetry monitoring tests which are carried out on our nuclear workers.
An assessment confirmed that the radiation dose received was significantly less than the annual limit allowed for an individual.
The employee suffered no ill effects and did not require any time off work.
While carrying out analysis work in a Sellafield site laboratory, a worker spilled approximately 1kg of depleted uranium trioxide powder while moving a container.
The material is not harmful unless ingested or inhaled.
The correct safety procedures were followed and the immediate area was evacuated before returning to normal service on the same day.
Health checks confirmed the worker suffered no ill effects.
An internal investigation is being carried out.
Sellafield is regulated by the Office for Nuclear Regulation and the Environment Agency.
Some of these reports are graded using the International Nuclear and Radiological Event Scale (INES).
