NUCLEAR REGULATORY COMMISSION
[Docket No. 50-131]
Department of Veterans Affairs; Nebraska--Western Iowa Health
Care System; Alan J. Blotcky Reactor Facility; Environmental Assessment
and Finding of No Significant Impact
The U.S. Nuclear Regulatory Commission (NRC) is considering
issuance of an amendment for Facility Operating License No. R-57,
issued to the Department of Veterans Affairs, Nebraska--Western Iowa
Health Care System (the licensee or VA) for operation of the Alan J.
Blotcky Reactor Facility (AJBRF) located in Omaha, Douglas County,
Nebraska.
Environmental Assessment
Identification of the Proposed Action
The proposed action would renew the license for the AJBRF for 20
years from the date of issuance of the license amendment. The proposed
action is in accordance with the licensee's application for amendment
dated May 10, 1993, as supplemented on March 1, 1995, December 17,
1997, March 12, April 5, July 29, November 24 and December 2, 1999,
January 4, September 25, October 2 and October 24, 2000, and August 8
and October 16, 2001. In
[[Page 59268]]
accordance with 10 CFR 2.109, the license remains in effect until the
NRC takes final action on the renewal application.
Need for the Proposed Action
The proposed action is needed to allow continued operation of the
AJBRF in order to continue educational training and academic research
beyond the current term of the license.
Environmental Impact of the Proposed Action
The AJBRF is located in the basement of the Department of Veterans
Affairs, Nebraska--Western Iowa Health Care System, Omaha Division
(formerly known as the VA Medical Center Omaha) in Omaha, Nebraska. The
main hospital building is 11 stories high and is constructed of brick
and reinforced concrete construction, including the ceilings and
floors. The hospital building is built on a knoll in a commercial area
within the city limits. To the north is a large county hospital, to the
south a commercial district, to the west a residential area, and to the
east a golf course. The medical center grounds are sufficiently large
so that the nearest offsite dwelling is more than 520 ft. (158 m) away.
The reactor is located near the bottom of a cylindrical pool 20 ft
(6.1 m) below the floor of the reactor room. The only access to the
reactor pool is from the top. The reactor control console is located
near the reactor pool in the reactor room.
On June 24, 1959, the U.S. Atomic Energy Commission (AEC) issued VA
a Construction Permit (CPRR-36) authorizing construction of a General
Atomics TRIGA-type research reactor. On June 26, 1959, Facility
Operating License No. R-57 was issued authorizing VA to operate the
TRIGA reactor at steady-state power levels up to 10 kW(t). The reactor
first reached criticality on June 30, 1959. Amendment No. 2 to the
license issued in September 1963 increased the steady-state thermal
power level of the reactor to 18 kW(t) and Amendment No. 9 issued in
April 1991 increased the power level to 20 kW(t). The license has been
renewed twice prior to this renewal with the last renewal issued in
August 1983. The licensee submitted an updated safety analysis report
and technical specifications as part of the application for license
renewal. Over the last ten years the facility has operated an average
of 344 full power hours per year. Facility modifications have been
minor. The licensee has not indicated any plans to significantly change
the design of the facility.
The radioactive releases from the AJBRF have been well within
regulatory limits of 10 CFR part 20. Argon-41, a product from neutron
irradiation of air during operation, is the principle airborne
radioactive effluent from the AJBRF during routine operations. During
the last 10 years, the licensee has calculated that the amount of
argon-41 discharged from the facility to the environment has ranged
from 1 mCi (37 MBq) to 300 mCi (11,100 MBq) per year. The maximum dose
to members of the public has been less than 1 mrem (0.01 mSv) per year.
The staff calculates that even given continuous operation of the
reactor, the maximum dose to members of the public would still be less
than 1 mrem (0.01 mSv) per year.
Over the last ten years the licensee has released no liquid or
solid waste from the AJBRF. Any future releases would be performed
within the requirements of the regulations.
Currently, there are no plans to change any operating or
radiological release practices or characteristics of the reactor during
the license renewal period. The NRC concludes that conditions are not
expected to change and that the radiological effects of operation
during the renewal period will continue to be minimal. The radiological
exposures for facility operations have been within regulatory limits
and should continue to remain so.
The proposed action will not significantly increase the probability
or consequences of accidents, no changes are being made in the types of
any effluents that may be released off site, and there is no
significant increase to occupational or public radiation exposure.
Therefore, there are no significant radiological environmental impacts
associated with the proposed action.
With regard to potential non-radiological impacts, the proposed
action does not involve any historic sites. It does not affect non-
radiological facility effluents and has no other environmental impact.
Therefore, there are no significant non-radiological environmental
impacts associated with the proposed action.
In addition, the environmental impact associated with operation of
research reactors has been generically evaluated by the staff and is
discussed in the attached generic evaluation. This evaluation concludes
that no significant environmental impact is associated with the
operation of research reactors licensed to operate at power levels up
to and including 2 megawatts thermal. The NRC staff has determined that
this generic evaluation is applicable to operation of the AJBRF and
that there are no special or unique features that would preclude
reliance on the generic evaluation.
Accordingly, the NRC concludes that there are no significant
environmental impacts associated with the proposed action.
Alternatives to the Proposed Action
As an alternative to the proposed action, the staff considered
denial of the proposed action (i.e., the ``no-action'' alternative). If
the NRC denied license renewal, AJBRF operations would stop and
decommissioning would be required with no significant benefit to the
environment. The environmental impacts of the proposed action and
alternative are similar.
Alternative Use of Resources:
This action does not involve the use of any resources not
previously considered in the safety analysis and evaluation for the
operating license renewal in 1983.
Agencies and Persons Contacted
In accordance with its stated policy, on June 19, 2001, the staff
consulted with the Nebraska State official, Ms. Julia Schmitt of the
Nebraska Department of Health and Human Services Regulation and
Licensure, regarding the environmental impact of the proposed action.
The State official had no comment.
Finding of No Significant Impact
On the basis of the environmental assessment, the NRC concludes
that the proposed action will not have a significant effect on the
quality of the human environment. Accordingly, the NRC has determined
not to prepare an environmental impact statement for the proposed
action.
For further details with respect to the proposed action, see the
licensee's letter dated May 10, 1993, as supplemented on March 1, 1995,
December 17, 1997, March 12, April 5, July 29, November 24 and December
2, 1999, January 4, September 25, October 2 and October 24, 2000, and
August 8 and October 16, 2001. Documents may be examined, and/or copied
for a fee, at the NRC's Public Document Room, located at One White
Flint North, 11555 Rockville Pike (first floor), Rockville, Maryland.
The NRC maintains an Agencywide Documents Access and Management System
(ADAMS), which provides text and image files of NRC's public documents.

Environmental Considerations Regarding the Licensing of Research
Reactors and Critical Facilities
Introduction
This discussion deals with research reactors and critical
facilities which are designed to operate at low power levels, 2 MWt
and lower, and are used primarily for basic research in neutron
physics, neutron radiography, isotope production, experiments
associated with nuclear engineering, training and as a part of a
nuclear physics curriculum. Operation of such facilities will
generally not exceed a 5-day week, 8-hour day, or about 2000 hours
per year. Such reactors are located adjacent to technical service
support facilities with convenient access for students and faculty.
Sited most frequently on the campuses of large universities, the
reactors are usually housed in already existing structures,
appropriately modified, or placed in new buildings that are designed
and constructed to blend in with existing facilities. However, the
environmental considerations discussed herein are not limited to
those facilities which are part of universities.
Facility
There are no exterior conduits, pipelines, electrical or
mechanical structures or transmission lines attached to or adjacent
to the facility other than for utility services, which are similar
to those required in other similar facilities, specifically
laboratories. Heat dissipation, if required, is generally
accomplished by a heat exchanger whose secondary side includes a
cooling tower located on the roof of or nearby the reactor building.
The size of these cooling towers typically are on the order of 10 ft
by 10 ft by 10 ft (3 m by 3 m by 3 m) and are comparable to cooling
towers associated with the air-conditioning systems of large office
buildings. Heat dissipation may also be accomplished by transfer
through a heat exchanger to water flowing directly to a sewer or a
chilled water system. Make-up for the cooling system is readily
available and usually obtained from the local water supply.
Radioactive gaseous effluents during normal operations are
usually limited to argon-41. The release of radioactive liquid
effluents can be carefully monitored and controlled. Liquid wastes
are collected in storage tanks to allow for decay and monitoring
prior to dilution and release to the sanitary sewer system or the
environment. This liquid waste may also be solidified and disposed
of as solid waste. Solid radioactive wastes are packaged and shipped
offsite for storage or disposal at NRC-approved sites. The
transportation of such waste is done in accordance with existing
NRC-DOT regulations in approved shipping containers.
Chemical and sanitary waste systems are similar to those
existing at other similar laboratories and buildings.
Environmental Effects of Site Preparation and Facility Construction
Construction of such facilities invariably occurs in areas that
have already been disturbed by other building construction and, in
some cases, solely within an already existing building. Therefore,
construction would not be expected to have any significant effect on
the terrain, vegetation, wildlife or nearby waters or aquatic life.
The societal, economic and aesthetic impacts of construction would
be no greater than those associated with the construction of an
office building or similar research facility.
Environmental Effects of Facility Operation
Release of thermal effluents from a reactor of less than 2 MWt
will not have a significant effect on the environment. This small
amount of waste heat is generally rejected to the atmosphere by
means of small cooling towers. Extensive drift and/or fog will not
occur at this low power level. The small amount of waste heat
released to sewers, in the case of heat exchanger secondary flow
directly to the sewer, will not raise average water temperatures in
the environment.
Release of routine gaseous effluents can be limited to argon-41,
which is generated by neutron activation of air. In most cases, this
will be kept as low as practicable by using gases other than air for
supporting experiments. Experiments that are supported by air are
designed to minimize production of argon-41. Yearly doses to persons
in unrestricted areas will be at or below established 10 CFR part 20
limits. Routine releases of radioactive liquid effluents can be
carefully monitored and controlled in a manner that will ensure
compliance with the regulations. Solid radioactive wastes will be
shipped in approved containers to an authorized disposal site or to
a facility licensed to treat and consolidate radioactive waste.
These wastes should not require more than a few shipping containers
a year.
Based on experience with other research reactors, specifically
TRIGA reactors operating in the 1 to 2 MWt range, the annual release
of gaseous and liquid effluents to unrestricted areas should be less
than 30 curies (1,110,000 MBq) and 0.01 curies (370 MBq),
respectively.
No release of potentially harmful chemical substances will occur
during normal operation. Small amounts of chemicals and/or high-
solid content water may be released from the facility through the
sanitary sewer during periodic blowdown of the cooling tower or from
laboratory experiments. The quality of secondary cooling water may
be maintained using biocides, corrosion inhibitors and pH control
chemicals. The use of these chemicals for this purpose is approved
by the Environmental Protection Agency (EPA). The small amounts of
laboratory chemicals that may be used in research laboratories are
disposed of in accordance with EPA and state requirements.
Other potential effects of the facility, such as aesthetics,
noise, societal or impact on local flora and fauna are expected to
be too small to measure.
Environmental Effects of Accidents
Accidents ranging from the failure of experiments up to the
largest core damage and fission product release considered possible
result in doses that are less than 10 CFR part 20 limits and are
considered negligible with respect to the environment.
Unavoidable Effects of Facility Construction and Operation
The unavoidable effects of construction and operation involve
the materials used in construction that cannot be recovered and the
fissionable material used in the reactor. No adverse impact on the
environment is expected from either of these unavoidable effects.
Alternatives to Construction and Operation of the Facility
To accomplish the objectives associated with research reactors,
there are no suitable alternatives. Some of these objectives are
training of students in the operation of reactors, production of
radioisotopes, and use of neutron and gamma ray beams to conduct
experiments.
Long-Term Effects of Facility Construction and Operation
The long-term effects of research facilities are considered to
be beneficial as a result of the contribution to scientific
knowledge and training. Because of the relatively small amount of
capital resources involved and the small impact on the environment,
very little irreversible and irretrievable commitment is associated
with such facilities.
Costs and Benefits of Facility Alternatives
The costs are on the order of several millions of dollars with
very little environmental impact. The benefits include, but are not
limited to, some combination of the following: conduct of activation
analyses, conduct of neutron radiography, training of operating
personnel, and education of students. Some of these activities could
be conducted using particle accelerators or radioactive sources
which would be more costly and less efficient. There is no
reasonable alternative to a nuclear research reactor for conducting
this spectrum of activities.
Conclusion
The staff concludes that there will be no significant
environmental impact associated with the licensing of research
reactors or critical facilities designed to operate at power levels
of 2 MWt or lower and that no environmental impact statements are
required to be written for the issuance of construction permits,
operating licenses or license renewals for such facilities.
