Priority Criteria
Three priorities, noted 1, 2 and 3 (l "being the highest),
can be attributed to the requests. The priorities are defined
as follows:
* Priority 1 *
Nuclear data which satisfy the criteria of Priority 2
and which have been selected for maximum practicable
attention, taking into account the urgency of nuclear
energy programme requirements.
For example, the European American Committee for
Reactor Physics assigns its highest priorities for reactor
measurements as follows:
"The highest priority should be given to requests
for nuclear data for reactors to be built in the near
future if:
a. These data are still necessary to predict the
different reactor properties after all information from
integral experiments and operating reactors has been used;
or
b. information on an important reactor parameter is
in principle attainable through mathematical calculation
from nuclear data only; or
c. these data are needed for materials required in
reactor physics measurements."
