BBC News reports that The UK government must "get a grip" on spiralling costs and project delays that have plagued the Sellafield nuclear site, located on the far side of the Irish Sea on the Cumbrian coast, approximately 170 km (112 miles) from the northeast coast of Ireland, just 128 miles from Dublin.

The UK's Public Accounts Committee (PAC) said in a report that some decommissioning projects had already been delayed by more than a decade.

It said estimated budget overruns had climbed to nearly £1bn.

The complex in Cumbria includes three old experimental nuclear reactors, four shut down nuclear power plants and thousands of tonnes of radioactive fuel and high-level wastes.

Sellafield is home to 40% of the world's stock of plutonium which is used to make nuclear bombs.

The committee expressed concerns about the government's lack of clarity over what to do with the stockpile.

MPs acknowledged that progress had been made in reducing risk and removing waste.

However, they said the Nuclear Decommissioning Authority, which is responsible for winding down and cleaning up the site in Cumbria, had not reviewed why projects kept running into difficulties.

Sir Geoffrey Clifton-Brown, deputy chairman of the PAC, said that the Department for Business, Energy and Industrial Strategy "needs to seriously get a grip on its oversight of nuclear decommissioning in this country".

#IrishSea - One million cubic metres of radioactive waste at a dump site near Sellafield is at risk of contaminating the Irish Sea in the future, according to papers released by Britain's Environment Agency.

According to The Guardian, the internal report says it is "doubtful" whether the location of the Drigg Low-Level Waste Repository (LLWR) on the Cumbrian coast "would be chosen for a new facility for near-surface radioactive waste disposal if the choice were being made now."

Though the full effects of coastal erosion, weathering and flooding are not expected to be felt until "a few hundred to a few thousand years from now", the agency has expressed worry over the site's gradual exposure to the elements.

This is compounded by fears that past deposits at the site over the last 55 years have included higher-level radioactive waste than intended.

#SELLAFIELD - Radioactive waste stored at Sellafield poses an "intolerable risk" to the environment, according to the UK's National Audit Office.

RTÉ News reports that a new study from the British government department watchdog highlights the failure of successive operators of the UK's largest nuclear plant to properly dispose of waste from the facility over more than 50 years.

The complex, on the coast of the Irish Sea in Cumbria, is said to contain enough contaminated waste to fill 27 Olympic-sized swimming pools.

Marine Institute Research Vessel Tom Crean

Ireland’s new marine research vessel will be named the RV Tom Crean after the renowned County Kerry seaman and explorer who undertook three major groundbreaking expeditions to the Antarctic in the early years of the 20th Century which sought to increase scientific knowledge and to explore unreached areas of the world, at that time.

Ireland's new multi-purpose marine research vessel RV Tom Crean, was delivered in July 2022 and will be used by the Marine Institute and other State agencies and universities to undertake fisheries research, oceanographic and environmental research, seabed mapping surveys; as well as maintaining and deploying weather buoys, observational infrastructure and Remotely Operated Vehicles.

The RV Tom Crean will also enable the Marine Institute to continue to lead and support high-quality scientific surveys that contribute to Ireland's position as a leader in marine science. The research vessel is a modern, multipurpose, silent vessel (designed to meet the stringent criteria of the ICES 209 noise standard for fisheries research), capable of operating in the Irish Exclusive Economic Zone (EEZ). The Tom Crean is able to go to sea for at least 21 days at a time and is designed to operate in harsh sea conditions.

  • Main Propulsion Motor 2000 kw
  • Bow Thruster 780 kw
  • Tunnel thruster 400 kw

Other

  • Endurance  21 Days
  • Range of 8,000 nautical miles
  • DP1 Dynamic Positioning
  • Capacity for 3 x 20ft Containers

Irish Marine Research activities

The new state-of-the-art multi-purpose marine research vessel will carry out a wide range of marine research activities, including vital fisheries, climate change-related research, seabed mapping and oceanography.

The new 52.8-metre modern research vessel, which will replace the 31-metre RV Celtic Voyager, has been commissioned with funding provided by the Department of Agriculture, Food and the Marine approved by the Government of Ireland.

According to Aodhán FitzGerald, Research Vessel Manager of the MI, the RV Tom Crean will feature an articulated boom crane aft (6t@ 10m, 3T@ 15m), located on the aft-gantry. This will be largely used for loading science equipment and net and equipment handling offshore.

Mounted at the stern is a 10T A-frame aft which can articulate through 170 degrees which are for deploying and recovering large science equipment such as a remotely operated vehicle (ROV’s), towed sleds and for fishing operations.

In addition the fitting of an 8 Ton starboard side T Frame for deploying grabs and corers to 4000m which is the same depth applicable to when the vessel is heaving but is compensated by a CTD system consisting of a winch and frame during such operations.

The vessel will have the regulation MOB boat on a dedicated davit and the facility to carry a 6.5m Rigid Inflatable tender on the port side.

Also at the aft deck is where the 'Holland 1' Work class ROV and the University of Limericks 'Etain' sub-Atlantic ROV will be positioned. In addition up to 3 x 20’ (TEU) containers can be carried.

The newbuild has been engineered to endure increasing harsher conditions and the punishing weather systems encountered in the North-East Atlantic where deployments of RV Tom Crean on surveys spent up to 21 days duration.

In addition, RV Tom Crean will be able to operate in an ultra silent-mode, which is crucial to meet the stringent criteria of the ICES 209 noise standard for fisheries research purposes.

The classification of the newbuild as been appointed to Lloyds and below is a list of the main capabilities and duties to be tasked by RV Tom Crean:

  • Oceanographic surveys, incl. CTD water sampling
  • Fishery research operations
  • Acoustic research operations
  • Environmental research and sampling operation incl. coring
  • ROV and AUV/ASV Surveys
  • Buoy/Mooring operations
