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.

For most pressurized water reactors, moderator temperature coefficients (MTCs) must be measured at end-of-cycle conditions at power to verify that Technical Specification limits on negative MTC will not be violated. Three techniques for performing these measurements are evaluated, and the relative strengths and weaknesses of each method are discussed. Considering overall accuracy and time required to perform the test, a best method is selected, and its accuracy is compared with previous measurements performed at Davis-Besse Unit 1, thus demonstrating the effectiveness of this technique. In addition, the necessity of attempting to perform this measurement at power at end-of-life conditions is discussed.
