TO IRRADIATE TWO U3Si2 PROTOTYPE FUEL
ELEMENTS IN THE RA-3 RESEARCH REACTOR
Regulatory Authority - Argentina
RA-3 research reactor (with U3O8-Al LEU MTR fuel type
elements and in the process to increase its power from 5 MW to 10 MW since
October 2002) is operated by the National Atomic Energy Commission (CNEA).
evaluating the safety studies submitted by CNEA, the Argentine Nuclear
Regulatory Authority (ARN) authorised the irradiation of two U3Si2-Al
prototype fuel elements named P‑06 and P-07, in the RA-3, in September
2000 and September 2001 respectively. These irradiations are part of the
qualification programme as manufacturer (CNEA).
This report contains a brief
description of the regulatory process the ARN carries out in order to approve
major modifications or new experiments in research reactors; it also summarises conditions in force for operable core
configurations, considers a definition of prototype fuel element and lists the
main characteristics of the RA-3 research reactor. Then, the process involved
in the authorisation to irradiate the prototypes P-06
and P-07 is particularly analysed.
in case an authorisation to irradiate a prototype fuel element of a non-qualified
material (such as U-Mo) in the RA-3 is requested, the regulatory aspects that
should be taken into consideration are analysed. This would be the first time a
question of this nature is submitted to the ARN.
