U.K.’s NWS gets input from young people on geological disposal
Nuclear Waste Services, the radioactive waste management subsidiary of the United Kingdom’s Nuclear Decommissioning Authority, has reported on its inaugural year of the National Youth Forum on Geological Disposal forum. NWS set up the initiative, in partnership with the environmental consultancy firm ARUP and the not-for-profit organization The Young Foundation, to give young people the chance to share their views on the government’s plans to develop a geological disposal facility (GDF) for the safe, secure, and long-term disposal of radioactive waste.

Technical Paper | Special Issue on the RELAP5-3D Computer Code | doi.org/10.13182/NT15-5
Articles are hosted by Taylor and Francis Online.
The RELAP5-3D system analysis code is a generic and flexible analysis program that is used for the analysis of steady-state and transient scenarios of nuclear reactors. While RELAP5-3D has been successfully applied to a very large range of problems, other analysis tools exist that provide either additional accuracy or capability. This paper describes an extensible integrated code system that utilizes the RELAP5-3D analysis code in conjunction with the R5EXEC executive. A description of the different types of time-step algorithms and data transfer methods is provided. Discussions of the various strengths and weaknesses of the coupled code system are provided. Finally, examples of how the coupled code system has been exercised are included.
