The UK Chemical Nuclear Data Libraries: Evaluated Nuclear Decay Data for Reactor Applications

The United Kingdom Chemical Nuclear Data Committee has the responsibility for the development and maintenance of libraries of evaluated nuclear decay and fission yield data for use in the UK nuclear power programme. Currently the libraries contain decay data for 91 activation products (UKPADD-1), 125 heavy element nuclides (UKHEDD-1) and 855 fission product nuclides (UKFPDD-2) together with fission yield data (CROUCH 31). The present contents and the methods of file construction are described together with the available means of producing suitable data tabulations.
