RADIOMETRIC INSTRUMENTATION FOR BU.RNUP CREDIT, SAFEGUARDS AND WASTE CHARACTERIZATION OF SPENT FUEL

I%e potential applications of spent fiel monitoring include actiw”ties such as; the use of burnup credit for the storage, transport and disposa[ of spent fiel, safeguards inventoty verification and radionucliak inventory &term”nation. i%vorecently published documents consiakr in detail the issues of bumup credit and the management of plutom”um i%is paper desm-ba the rekvance of spent fiel moniton”ng,partJ”cularlyfor bumup measurement, to these and to waste charactdzation activities. The techniques available for burnup measurement and how the drta from such measurements may be used are preented Finally recommenhtions are g“ven on methoa3 of calibration and the use of measurement systems to provide an acceptable level of conjiaknce in the measurement result to allow thee activitt”as to take place safely and with the support of the regulators and thepubiic.
