关于核物理,核化学的专业英译汉,
If the material involved is a ceramic oxide powder,no melting/softening is postulated that no
significant fraction of the non-volatile fission products generated are released.Due to the
size of the individual particles in a powder,it is assumed that the fraction of volatile fission
products (noble gases,iodine,ruthenium) present are so close to the surface that they are
released in the following fractions:5E-1 of the noble gases; 5E-2 of the iodine; and,2E-3 of
the ruthenium.
Other groupings of radionuclides are possible.For instance,ruthenium is unique in that it
can readily form volatile oxides under appropriate conditions.Ruthenium could be logically
included with the Transition Metals increasing its release fraction from 2E-3 to 3E-2 (greater
than an order-of-magnitude increase).The ARF for the Alkali Metals is 4 times greater than
for the Halogens and is difficult to justify.Generally,the elements in the Main Group I
elements appear to be more volatile than the elements included in the Main Group II category
although both are assigned the same ARF.The role of cladding is critical for the Chalogens
(Group V) elements especially Te for which significant interactions with the cladding are
predicted in all but very oxidizing conditions.Ba releases appear to be high and such values
only occur for very reducing conditions.The ARFs are those determined from the evaluation of the most recent experiments on irradiated field heating and may not reflect
response for lesser conditions.
