Sellafield awards $6B ‘high hazard risk reduction’ framework contract
Sellafield Ltd., the site license company overseeing the decommissioning of the United Kingdom’s Sellafield nuclear site in Cumbria, England, has awarded a 15-year framework contract worth up to £4.6 billion ($6 billion) to support “high hazard risk reduction programs” at the site.

A combination fission-radioisotope compact power system involving the synergetic interaction of 251Cf and 252Cf is considered. Based on a nonlinear point kinetics formulation of the coupled reactions combined with the parametric incorporation of design and operational variables, it is shown that a stable autonomous power mode is readily attainable. This system appears particularly suitable for very long-life unattended operation for space and terrestrial applications.
