11.1 Radiation Protection Program
Areas of Review
HEU TO LEU CONVESION
No significant changes in the radiation protection program are expected to result
from changes in reactor systems, operating conditions, or procedures that were
required by the conversion from HEU to LEU fuel.'
The reviewer should evaluate
the potential sources of radiation at a research reactor (including if
appropriate criticality monitors to comply with 10 CER 70.24 requirements
for fuel storage)
* the provisions made by the licensee to detect and measure all potential
reactor-related sources
* the provisions made to assess potential exposures and doses to the facility
staff and the public
* measures being taken to limit doses to within applicable regulations
* commitment to an ALARA program for potential exposures
* ongoing assessment of the effectiveness of the radiation protection
programs .
If the conversion of the reactor from HEU to LEU fuel requires modifications to
the facility or changes to operating conditions, limits, or procedures, the reviewer
should confirm that the licensee has addressed the effects of these changes on the
radiation protection program at the facility.
Acceptance Crteria
Acceptance criteria should be based on the following considerations: Any
proposed changes to the radiation protection program or its implementation should
be related to the conversion of the reactor from HEU to LEU fuel. Any changes
to the radiation protection program'should not significantly decrease the level of
protection provided to the public, the facility staff or the environment. The
licensee's analytical methods and assumptions should be applicable to non-power
reactors, conmmensurate with the types and magnitudes of radiological risks at the
facility, and consistent with the existing prograim for the HEU-fueled reactor. The
program shall continue to comply with the requirements of 10 CFR Part 20 and the
facility-specific ALARA program.
