“…Short lived fission products have decayed to insignificant concentrations since the fuel ceased being irradiated in 1974. The radionuclide activity and decay heat of the fuel assemblies were determined by ORlGEN2 analysis based on the bulk composition and known operational history (Bergsman 1994). The activity and decay heat results are shown in Table 6-2 (shown on previous page) at 10,20,25, and 30 years since irradiation.…”

GLOSSARY OF TERMS ACTIVITYActivity i s a measure of quantity of a radioactive substance. The SI u n i t of measure i s the becquerel (B ) which i s equal t o the amount of substance from which one disintegration 9 nuclear transformation) per second i s obtained. The common unit of activity is the curie (Ci) which i s equal t o 37 billion disintegrations per second -t h a t number of disintegrations i s approximately the disintegration rate of one gram (0.04 oz) of radium from which the original definition came. One Ci equals 3.7 x 10" Bq.While activity gives a measure of rate of radioactive decays of a substance, i f used alone i t may be misleading. The half-life of the substance, or the time i t takes for one half of the activity t o have disappeared i s also important. For example one unit of activity of cesium-137 (half-life about 30 years) will have diminished t o about 1% of the i n i t i a l amount in 200 years, whereas one u n i t of activity of iodine-129 (half-life about 16 million years), for a l l practical purposes, will not have diminished a t a l l .BECQUEREL See Activity. CR I T I CALI TYCriticality typically refers t o a condition where masses o f f i s s i l e material have exceeded the size, geometry and neutron moderation t o result in a spontaneous self-sustaining nuclear chain reaction in which there i s an exact balance between production and loss of neutrons in the absence of extraneous sources. The result i s emission of radiation and release of considerable quantities of fission products. the usual sense, however dose rates near a c r i t i c a l i t y event can be very high t o lethal. Extraordinary precautions are taken t o assure that the . conditions for accidental c r i t i c a l i ty do not exi s t .The event i s not explosive in CURIE See Activity .
