Wetted Failed Fuel Radiolysis Reference number: NNLC178

NNL are currently contracted to carry out a series of trials to measure radiolytic gas generation. Because these measurements are to be made using irradiated material there are two significant constraints: • The quantity of material (predominantly a powder) used in each test must be minimised. • The samples and vessels must remain within a hot cell facility (see Appendix for details), therefore: o Sample lines between the text vessels and the measurement system located outside the hot cell will be long (~6-10 m...
