Utah Admin. Code R313-25-9 - Technical Analyses
(1) The licensee or
applicant shall conduct a site-specific performance assessment and receive
Director approval prior to accepting any radioactive waste if:
(a) the waste was not considered in the
development of the limits on Class A waste and not included in the analyses of
the Draft Environmental Impact Statement on 10 CFR Part 61 "Licensing
Requirements for Land Disposal of Radioactive Waste ," NUREG-0782. U.S. Nuclear
Regulatory Commission . September 1981, or
(b) the waste is likely to result in greater
than 10 percent of the dose limits in Section
R313-25-19
during the time period at which peak dose would occur, or
(c) the waste will result in greater than 10
percent of the total site source term over the operational life of the
facility , or
(d) the disposal of
the waste would result in an unanalyzed condition not considered in Rule
R313-25.
(2) A licensee
that has a previously-approved site-specific performance assessment that
addressed a radioactive waste for which a site-specific performance assessment
would otherwise be required under Subsection R313-25-9(1) shall notify the
Director of the applicability of the previously-approved site-specific
performance assessment at least 60 days prior to the anticipated acceptance of
the radioactive waste .
(3) The
licensee shall not accept radioactive waste until the Director has approved the
information submitted pursuant to Subsections R313-25-9(1) or (2).
(4) The licensee or applicant shall also
include in the specific technical information the following analyses needed to
demonstrate that the performance objectives of Rule R313-25 will be met:
(a) Analyses demonstrating that the general
population will be protected from releases of radioactivity shall consider the
pathways of air, soil, ground water, surface water, plant uptake, and
exhumation by burrowing animals. The analyses shall clearly identify and
differentiate between the roles performed by the natural disposal site
characteristics and design features in isolating and segregating the wastes.
The analyses shall clearly demonstrate a reasonable assurance that the
exposures to humans from the release of radioactivity will not exceed the
limits set forth in Section
R313-25-20.
(b) Analyses of the protection of inadvertent
intruders shall demonstrate a reasonable assurance that the waste
classification and segregation requirements will be met and that adequate
barriers to inadvertent intrusion will be provided.
(c) Analysis of the protection of individuals
during operations shall include assessments of expected exposures due to
routine operations and likely accidents during handling, storage, and disposal
of waste . The analysis shall provide reasonable assurance that exposures will
be controlled to meet the requirements of Rule R313-15.
(d) Analyses of the long-term stability of
the disposal site shall be based upon analyses of active natural processes
including erosion, mass wasting, slope failure, settlement of wastes and
backfill, infiltration through covers over disposal areas and adjacent soils,
surface drainage of the disposal site , and the effects of changing lake levels.
The analyses shall provide reasonable assurance that there will not be a need
for ongoing active maintenance of the disposal site following
closure.
(5)
(a) Notwithstanding Subsection R313-25-9(1),
any facility that proposes to land dispose of significant quantities of
concentrated depleted uranium (more than one metric ton in total accumulation)
after June 1, 2010, shall submit for the Director 's review and approval a
performance assessment that demonstrates that the performance standards
specified in 10 CFR Part 61 and corresponding provisions of Utah rules will be
met for the total quantities of concentrated depleted uranium and other wastes,
including wastes already disposed of and the quantities of concentrated
depleted uranium the facility now proposes to dispose. Any such performance
assessment shall be revised as needed to reflect ongoing guidance and
rulemaking from NRC. For purposes of this performance assessment, the
compliance period shall be a minimum of 10,000 years. Additional simulations
shall be performed for the period where peak dose occurs and the results shall
be analyzed qualitatively.
(b) No
facility may dispose of significant quantities of concentrated depleted uranium
prior to the approval by the Director of the performance assessment required in
Subsection R313-25-9(5)(a).
(c) For
purposes of this Subsection R313-25-9(5) only, "concentrated depleted uranium "
means waste with depleted uranium concentrations greater than 5 percent by
weight.
