A method for determining nitride nitrogen was adapted for analyses of irradiated samples in a hot cell. Sections of stainless steel cladding material or fuel are dissolved remotely using various combinations of H/sub 2/SO/sub 4/, HCl, and HF. The nitrogen is separated from the highly radioactive sample solution by steam distillation using the Kjeldahl method. The collected distillates are moved from the hot cell to an open-front box where they are treated with Nessler's reagents for spectrophotometric measurement. The absorbance is measured at a 410-nm wavelength. The standard deviation for measuring 50 ..mu..g of nitrogen is < 2 ..mu..g of nitrogen using this method.
