NUCLEAR REGULATORY COMMISSION
[NRC-2009-0312; Docket No. 030-35985]
Environmental Assessment and Final Finding of No Significant
Impact With Regard to Exemption From Certain Regulatory Requirements
Introduction
The U.S. Nuclear Regulatory Commission (NRC) is proposing to exempt
all NRC medical use licensees from certain requirements in 10 CFR
35.60(b), 10 CFR 35.100(a)(1) and 35.200(a)(1), and 10 CFR 32.72. These
requirements govern calibration tests that use technetium-99m, and
distribution of molybdenum-99/technetium-99m generators and technetium-
99m radioactive drugs to and from medical use licensees. NRC is issuing
these exemptions to ensure that available technetium-99 is being used
for patient administrations during any period of United States and
worldwide shortages of molybdenum-99, which is used to produce
molybdenum-99/technetium-99m generators for medical use.
These exemptions will be effective only when there are United
States shortages of technetium-99m caused by production shortages of
molybdenum-99, as documented in writing by the supplier of molybedenum-
99/technetium-99m generators or technetium-99m.
Environmental Assessment
Identification of the Proposed Action
The NRC proposes to issue exemptions to all NRC medical use
licensees from the requirements in 10 CFR 35.60(b) to calibrate the
instrumentation required in paragraph (a) of this section in accordance
with nationally recognized standards. The licensee will not be required
to perform the calibration test at the maximum activity or at the time
interval specified in the national standard if the licensee would use
technetium-99m needed for a patient administration to perform the
calibration test. The exemption will only be in effect when the
licensee is receiving reduced quantities of technetium-99m as a result
of production shortages of molybdenum-99 affecting their generator or
technetium-99m supplier, as documented in writing by the supplier. The
licensee must perform the test when adequate supplies, as documented in
writing by the technetium-99 supplier, become available, and document
results of the test in accordance with 10 CFR 35.2060. Depending on the
maximum activity needed to perform the calibration test and the
activity of technetium-99m in the radioactive drug, this may make
dosages available to 7-15 additional patients at the licensee's
facility.
The NRC proposes to issue exemptions to all NRC medical use
licensees from the requirements in 10 CFR 35.100(a)(1) and 35.200(a)(1)
to obtain unsealed byproduct material prepared for medical use for
uptake, dilution, excretion, imaging or localization studies from a
manufacturer or preparer licensed under Sec. 32.72 of this chapter or
equivalent Agreement State requirements, if the licensee obtains the
technetium-99m (or a technetium-99m radioactive drug) from another
medical use licensee to administer to patients. This permits medical
use licensees that cannot get technetium-99m from their normal supplier
because of the shortage to obtain some technetium-99m from a local
medical use licensee that has a surplus. This exemption will only be in
effect when the licensee is unable to obtain technetium-99m (or a
technetium-99m radioactive drug) from its normal supplier as a result
of production shortages of molybdenum-99 affecting its generator or
technetium-99m supplier, as documented in writing by the supplier. This
exemption will give some relief on a case-by-case basis to a medical
use licensee if its supplier is severely affected by the shortage but
the other medical use licensee's supplier is not.
The NRC proposes to issue exemptions to all NRC medical use
licensees from requirements in 10 CFR 32.72, to permit the licensee to
transfer surplus molybdenum-99/technetium-99m generators or technetium-
99m, or technetium-99m radioactive drugs to other medical use licensees
for administration to patients without requiring the licensee to meet
the requirements for a commercial distributor of radioactive drugs to
medical use licensees. This exemption will only be in effect when the
receiving medical use licensee is unable to obtain a generator, or
technetium-99m or technetium-99m radioactive drugs from its normal
supplier, as a result of production shortages of molybdenum-99
affecting its generator or technetium-99m supplier, as documented in
writing by the supplier. This exemption will facilitate and give relief
on a case-by-case basis to a medical use licensee with a surplus of
technetium-99m (or a technetium-99m radioactive drug) because its
supplier is not affected by the shortage in the transfer of the
technetium-99m to the other medical use licensee whose supplier is
affected.

Need for the Proposed Action
These exemptions are needed in times of molybdenum-99 shortages in
the United States to ensure that available technetium-99m is used for
patient treatment. On May 14, 2009, the Chalk River National Research
Universal reactor in Canada experienced an unexpected shutdown that has
resulted in an extended shutdown for safety repairs. The Chalk River
reactor produces approximately 50 percent of the United States supply
of molybdenum-99 used to produce molybdenum-99/technetium-99m
generators. This resulted in a United States and worldwide shortage of
molybdenum-99 for generator production and technetium-99m for medical
uses. The High Flux Reactor in Petten, the Netherlands, also produces a
substantial amount of molybdenum-99 used to produce generators in the
United States and the world. The reactor in Petten is currently
operating on a temporary operating permit and expected to be shut down
in early 2010 for a number of months for repairs. This will also cause
molybdenum-99 and technetium-99m shortages in the United States and the
world. The supply chain for fission-produced isotopes is fragile and
may shrink dramatically at any time when these two, or the other three
aging international reactors currently producing these isotopes, are
shut down for safety or routine maintenance.
Environmental Impacts of the Proposed Action
During times of supply shortages, there is less molybdenum-99 and
technetium-99m available for molybdenum-99/technetium-99 generator
production. There are also fewer generators to elute, and fewer
technetium-99m radioactive drugs produced. The exemption will: (1)
Allow lower quantities of technetium-99m to be used for calibrations
and delay the calibration test, making quantities available for patient
administrations; (2) allow a licensee to obtain unsealed byproduct
material from another licensee other than directly from the
manufacturer or commercial nuclear pharmacy; and (3) allow a licensee
with sufficient product to transfer excess to another authorized
licensee for patient administration. The exemptions do not relieve the
licensee from NRC environmental release requirements or worker dose or
public dose requirements associated with the elution of molybdenum-99/
technetium-99m generators, preparation of technetium-99m radioactive
drugs, administration of the technetium-99m radioactive drugs to
patients, handling of these radioactive materials, or handling of
radioactive waste. All of those protections remain in place. Neither
molybdenium-99 nor technetium-99m is a volatile radionuclide.
Molybdenum-99 remains attached to the generator resins and technetium-
99m stays suspended in the eluent. Both radionuclides have short half-
lives. None of the proposed exemptions affects how the licensee handles
these radionuclides. Their medical use when there are no shortages
results in minimal impact on the environment and public dose exposures.
During times of shortage, medical use licensees will have less
technetium-99m to use and there will be fewer patients receiving
technetium-99m radioactive drugs even when maximizing the medical use
of available technetium-99m. Therefore, the proposed action will not
result in an increase in the release of radioactive material into the
environment or increase public radiation exposure. There will be no
impact on the environment as a result of the proposed action.
Alternatives to the Proposed Action
As required by Section 102(2)(E) of NEPA (42 U.S.C. 4322(2)(E)),
possible alternatives to the final action have been considered. The NRC
identified only one reasonable alternative for consideration: the no
action alternative. This no action alternative would not result in any
adverse impact on the environment but would negatively impact the
medical use licensees' provision of medical care to their patients.
During shortages in the United States and the world of molybdenum-99,
the supply of technetium-99m available to administer to patients is
less than the amount needed to perform important cardiac, cancer, and
other imaging procedures. Using technetium-99m to perform calibration
tests at maximum activities and at preset intervals instead of for
patient administrations would prevent a number of patients from
receiving these needed procedures. Temporary relief from the national
standards should not result in significantly different patient
radiation dosages because most instruments used to measure patient
dosages today are stable if not moved and provided with reasonable
climate controls. Also, performing the test at lower activity levels
will provide confidence that the instrument is still calibrated over
the levels of routine technetium-99m dosages. For higher dosages
requiring written directives, the licensee can use the activity
provided with the radioactive drug to assure patient safety. Not
granting an exemption to permit distribution to and receipt of excess
generators and technetium-99m by other authorized medical use licensees
that do not have any also would reduce the number of patients receiving
needed procedures. For these reasons, the NRC did not adopt the no
action alternative.
Alternative Use of Resources
No alternative use of resources was considered due to the reasons
stated above.
Agencies and Persons Consulted
No other agencies or persons were contacted regarding this proposed
action.
Identification of Source Used
None.
Finding of No Significant Impact
Based on the above environmental assessment, the NRC finds that the
proposed action will not have a significant effect on the quality of
the human environment. Accordingly, the NRC has determined that a
Finding of No Significant Impact is appropriate and preparation of an
environmental impact statement is not warranted.
