U.K. releases new plans to speed nuclear deployment
In an effort to revamp its nuclear sector and enable the buildout of new projects, the U.K. has unveiled a sweeping set of changes to project deployment. These changes, which are set to come into effect by the end of next year, will restructure the country’s regulatory and environmental approval framework and directly support new growth through various workforce efforts.

The thermal cross sections and the resonance integrals have been measured for the activation of Pm147 to both Pm148 isomers. The thermal activation cross sections are: 124 ± 13 barns to 5.39-day Pm148 and 111 ± 11 barns to 40.6-day Pm148m. The resonance integrals are: 1700 ± 250 barns to 5.39-day Pm148 and 1520 ± 230 barns to 40.6-day Pm148m. Approximate cross sections have been obtained for neutron capture by both Pm148 isomers. The pile cross section of 40.6-day Pm148m is 29,000 ± 5000 barns and is due mainly to thermal neutron capture. The pile cross section of 5.39-day Pm148 is 3,000 ± 2,000 barns and is due mainly to resonance neutron capture.
