Solid State Track Recorder (SSTR) neutron dosimetry measurements have been made in TMI-2 makeup Demineralizer A Cubicle in order to assess the amount of fuel debris present by means of the specific neutron activity of TMI-2 fuel. Based on recent calibration data and the results of the TMI-2 SSTR neutron dosimetry, the amount of fuel present is estimated to be 1.7 +- 0.6 kg. This value is in excellent agreement with a value determined independently by Compton recoil gamma-ray spectrometry. Sources of uncertainty in and proposed refinements of the present SSTR measurements are discussed.
