The Breakthrough Institute, Clean Air Task Force, ClearPath, Nuclear Innovation Alliance, and Third Way say delays in finalising a regulatory rulemaking on risk-informed emergency preparedness has already caused significant regulatory uncertainty for developers.

International Atomic Energy Agency staff have, after weeks of requests, been given access to the rooftops of reactor units 3 and 4 at the occupied Zaporizhzhia nuclear power plant and "observed no mines or explosives".

Drone pilots have successfully completed two flight firsts on the UK's Sellafield site which are expected to lead the way to increased safety of employees during decommissioning. Sellafield has now become the first UK nuclear site to employ a drone equipped with a radiation monitor.

Public consultation and a round-table discussion involving a variety of organisations has concluded that the proposed decommissioning plans for Leningrad 1 and 2 meet Russian and International Atomic Energy Agency standards. The next stage is to finalise the materials before submitting them as part of the process of obtaining the necessary national licences and approvals.

The US state of Alaska has adopted regulations to streamline the regulatory process for the siting of microreactors. The new regulations, which waive some requirements imposed on larger nuclear facilities, come into effect in August.

Unit 1 of the Takahama nuclear power plant in Japan's Fukui Prefecture has been restarted after being taken offline more than 12 years ago. Kansai Electric Power Company plans to return the 780 MWe (net) pressurised water reactor to commercial operation at the end of August.

Unit 4 at the Zaporizhzhia nuclear power plant has been switched to hot shutdown, with unit 5 switched from hot to cold shutdown to allow maintenance work to be carried out. Meanwhile the International Atomic Energy Agency reports it has seen "directional anti-personnel mines on the periphery of the site".

A framework agreement to extend the operation of the Doel 4 and Tihange 3 power reactors by 10 years has been signed between French utility Engie and the Belgian federal government. Meanwhile, Belgium's Federal Agency for Nuclear Control has set out "its expectations regarding nuclear safety" for the extended operation of the units.

The US Nuclear Regulatory Commission and Ghana's Nuclear Regulatory Authority have reaffirmed their cooperation on nuclear safety and regulation, part of wider cooperation between the two countries as Ghana aims to create a nuclear power programme.

International Atomic Energy Agency experts at the Zaporizhzhia nuclear power plant have carried out further inspections "so far without observing any heavy military equipment, explosives or mines" but are still awaiting access to the rooftops of the reactor buildings.
