NUCLEAR REGULATORY COMMISSION
[Docket 70-27]
Finding of No Significant Impact and Notice of Opportunity for a
Hearing, Renewal of Special Nuclear Material License SNM-42, Babcock &
Wilcox Company, Naval Nuclear Fuel Division, Lynchburg, VA
The U.S. Nuclear Regulatory Commission is considering the renewal
of Special Nuclear Material License SNM-42 for the continued operation
of the Babcock & Wilcox (B&W) Naval Nuclear Fuel Division (NNFD) and
Lynchburg Technology Center (LTC) in Lynchburg, Virginia.
Summary of the Environmental Assessment
Identification of the Proposed Action:
B&W has requested the renewal of Special Nuclear Material License
SNM-42 for the NNFD and LTC for a period of 10 years. In 1994, the NRC
approved the consolidation of all activities authorized under LTC's
License SNM-778 into NNFD's License SNM-42.
The B&W facility is located on a 212-hectare (525-acre) site in the
northeastern corner of Campbell County, approximately 8 km (5 miles)
east of Lynchburg, Virginia. This site is located in a generally rural
area, consisting primarily of rolling hills with gentle slopes,
farmland, and woodlands. The NNFD/LTC coexists on the site with the B&W
Fuel Company plant which is separately licensed by the NRC. The
combined NNFD/LTC facility is centrally located on the site with the
main manufacturing complex contained in a 7.7-hectare (19-acre) fenced
area and the LTC complex contained in a 5.5-hectare (13.6-acre) area
for a combined total of 13.2 hectares (32.6 acres).
With this renewal, the combined NNFD/LTC activities will continue.
The licensed activities include:
The fabrication of unirradiated, highly enriched uranium
into complete core assemblies for nuclear reactor fuel components for
the U.S. Navy propulsion program and other government agencies, as well
as university and other research reactors.
The recovery of process uranium from scrap material.
The continuation of existing research and development
operations and non-nuclear process control research.
The availability of analytical services for commercial
power plants.
The decontamination of reactor related hardware for
inspection and evaluation.
The Need for The Proposed Action
The NNFD operation primarily supports the U.S. Navy propulsion
program including fuel loading and subsequent refueling of ship
reactors. The demand for this operation will continue in order to
maintain at least the present fleet operation. If the operation of the
NNFD is discontinued, another facility will have to be used in order to
meet the national security needs of the U.S. Navy. In addition, this
facility provides nuclear fuel modules to U.S. Department of Energy
contractors and other research institutions. The LTC performs research
and development necessary to create new products and processes, along
with examining and improving those of the present generation.
Denial of license renewal for the NNFD/LTC facility would require
that similar activities be undertaken at another site.
Environmental Impacts of the Proposed Action
Renewal of the combined NNFD/LTC license, involves a balance of
positive and negative impacts. The positive impacts include
contribution to national security, lessening of dependence on fossil
fuels, and lessening of the negative environmental impacts related to
production and utilization of fossil fuels. The negative impacts
include releases of radioactive materials in the various environmental
media associated with facility operation.
For the proposed action, renewal of the combined NNFD/LTC license,
the continued handling of materials and conduct of operations at the
facility poses a potential impact to the environment and public health
and safety. For normal operations, the impact is related to the release
of low levels of toxic or radioactive materials to the environment over
extended periods of time. For accident conditions, the
[[Page 46631]]
hazard may involve release of higher concentrations of materials over
relatively short periods of time.
The nonradioactive gaseous emissions from the combined NNFD/LTC are
nitrogen oxides and fluoride compounds released from the process
buildings and combustion products released from the steam plant. The
state-issued air quality permit for the facility calls for the NOX
concentration at the site boundary to meet National Ambient Air Quality
Standards (NAAQS). It has been determined that a maximum sector annual
average NOX concentration is approximately 0.8 percent of the
NAAQS limit for NOX. Consequently, it is concluded that NOX
emissions produce an insignificant environmental impact (NRC, 1991).
The maximum hydrogen fluoride (HF) site boundary concentration is
estimated as 0.04 g/m \3\ . This concentration is
approximately 1 percent of the time weighted average threshold limit
value (TLV) proposed for workers by the American Conference of
Governmental Industrial Hygienists (ACGIH) (ACGIH, 1986). Consequently,
no significant impacts are expected.
Potential surface water impacts associated with operation of the
combined NNFD/LTC include disruption of flow of the James River due to
withdrawals and degradation of water quality of the river due to
contaminant releases. The design capacity for withdrawal by the B&W
facility is 0.02 m \3\/s (0.67 ft \3\/s). To date, this use of the
James River by the B&W facility has had no adverse impact on the James
River flow rate. The flow rates associated with future operations are
expected to be similar or less than the historical flows; no additional
impact is expected.
Degradation of surface water quality is prevented by enforcement of
release limits and monitoring programs mandated under the facility
National Pollution Discharge Elimination Systems (NPDES) permit. LTC
liquid discharges are a small part of the combined discharges, which
are monitored under this permit. NPDES permit conditions were exceeded
twice during the 1989 through 1993 period. In the first instance, the
discharge load for fluoride was exceeded during September 1993. In the
second instance, the permit level for fecal coliform was exceeded at an
internal monitoring point during July 1994 but was within limits at the
final release monitoring point. This infrequent exceedance of NPDES
levels does not indicate occurrence of a significant environmental
impact.
Potential groundwater impacts include drawdown of the water table
in the vicinity of facility wells and degradation of groundwater
quality due to uncontrolled leakage to the subsurface soils. The B&W
withdrawals of groundwater in the area of the James River are small in
comparison to the capacity of the wells and the groundwater system.
There are no discharges of waste waters to ponds that could result
in groundwater contamination from proposed operations except for those
ponds that are used to manage the flow rate of discharges into the
James River. The groundwater does have high levels of trichloroethylene
(TCE) contamination from previous leaks which have been identified and
eliminated.
On September 27, 1991, the Environmental Protection Agency (EPA)
Region III issued a Final Order of Consent (Docket RCRA-III-050-CA)
under Section 3008(h) of the Resource Conservation Reauthorization Act
(RCRA), as amended. The Consent Order specified that B&W perform
interim measures to prevent or relieve immediate threats to human
health or the environment, perform a RCRA field investigation (RFI) to
delineate the nature and extent of any releases of past raw products or
wastes, and to perform a corrective measures study (CMS) to identify
and evaluate alternatives for corrective action (B&W, 1995b).
On April 17, 1995, the draft RFI report was completed and submitted
to EPA Region III. The RFI report identified three groundwater plumes
which were contaminated with TCE, tetrachloroethylene (PCE), and
related degradation constituents above the drinking water limit of
0.005 parts per million (ppm). The largest plume (Plume A) is located
beneath the NNFD plant, extending 884 m (2,900 feet) from the upper
road on the southwest portion of the site northeast to the James River.
Plume A has a maximum width 365 m (1,200 feet), an approximate area of
28 hectares (70 acres), and an average concentration of 0.1 ppm TCE.
The TCE source areas for plume A are the former TCE storage tank
location where the maximum groundwater contamination is 145 ppm TCE,
and a former zirconium chip burning area near the James River where the
maximum groundwater contamination is 44.3 ppm TCE (B&W, 1995b).
The second largest plume (Plume C) is located beneath the
Commercial Nuclear Fuel Plant (CNFP), extending 503 m (1,650 feet) from
the upper side of the CNFP plant north towards the James River. Plume C
has a maximum width of 190 m (625 feet), an approximate area of 10
hectare (24 acres) and an average concentration of 0.01 ppm TCE. The
TCE source area for plume C is the former TCE storage tank location,
and the maximum groundwater contamination is 0.397 ppm TCE (B&W,
1995b).
The third largest plume (Plume B) is located on the western portion
of the site where the former uranium recovery building was buried.
Plume B has a maximum length of 229 m (750 feet), a maximum width of 90
meters (300 feet), an approximate area of 2 hectares (5 acres), and an
average concentration of 0.1 ppm TCE and 0.1 ppm PCE. The exact TCE and
PCE source areas for plume B are unknown, but are most likely due to
past waste disposal practices in the building disposal area. The
maximum groundwater contamination is 3.4 ppm TCE and 58.6 ppm PCE. Upon
EPA Region III approval of the RFI report, B&W will proceed with the
CMS, where alternatives for corrective action will be evaluated (B&W,
1995b).
All but two of the underground tanks installed at the site have
been removed and so the potential for accidental contamination of the
groundwater is reduced. Remediation plans are being prepared for the
cleanup of the TCE plume. The continued operation of the combined NNFD/
LTC is not expected to result in any additional negative impact on the
local groundwater.
Operation of the NNFD and LTC may pose risks to public health and
safety due to release of radioactive material under normal operational
or accident conditions. Radioactive materials released from the NNFD
and LTC may reach the public through a variety of transport pathways
contributing to both internal and external exposures. For atmospheric
releases; internal exposures may occur through inhalation of
radioactive material dispersed in the air or ingestion of crops and
animal products which come in contact with radioactive material
deposited from the air. External exposures may occur through direct
radiation from an airborne plume or from particulates deposited onto
the ground from the plume. For liquid releases, internal exposures from
ingestion of water or irrigated crops may occur. External exposures
from recreational activities, including swimming and boating may occur.
For atmospheric releases, potentially exposed members of the public
considered in the analysis include a maximally exposed individual
located at the site boundary and the population out to a distance of 80
kilometers (50 miles). In order to
[[Page 46632]]
provide a conservative evaluation of potential liquid pathway impacts,
the analysis assumes that a maximally exposed individual downstream of
the facility and the surrounding population obtain drinking water and
irrigation water from the James River.
The NNFD releases radioactive material to the atmosphere from
approximately 27 stacks while the LTC releases radioactive material
from 2 stacks. The NNFD releases are primarily uranium while the LTC
releases are mixed fission products, including H-3 and Kr-85. For
internal exposures, uranium is the dominant radionuclide; inhalation
exposures are greater than ingestion exposures, and the lung is the
controlling organ.
Low-level liquid radioactive waste from the NNFD and the LTC are
processed through the Waste Treatment Facility. The system effluent is
monitored and released to the James River. Releases attributable to the
NNFD are primarily uranium while those from the LTC are primarily
tritium.
NRC regulations (10 CFR 20.1301) require that total effective dose
equivalent (TEDE) for members of the public not exceed 1.0x10-\3\ Sv
(100 mrem) per year. In addition, EPA regulations (40 CFR Part 190)
require that for routine releases to the general environment, the
annual dose equivalent not exceed 2.5x10-\4\ Sv (25 mrem) to the whole
body, 7.5x10-\4\ Sv (75 mrem) to the thyroid, and 2.5x10-\4\ Sv (25
mrem) to any other organ (EPA, 1977). For releases to the atmosphere,
EPA regulations (40 CFR Part 61) require that the annual effective dose
equivalent not exceed 1.0x10-\4\ Sv (10 mrem) (EPA, 1991). Doses
associated with NNFD and LTC operations are dominated by releases to
the atmosphere. For the maximally exposed individual, TEDE is estimated
as 2.4x10-\7\ Sv (0.024 mrem) while the largest dose to a tissue is
estimated as 2.0x10-\6\ Sv (0.2 mrem) to the lung. The doses are small
fractions of the limits established by the NRC and EPA and indicate
that facility operations will have insignificant impact on public
health and safety. Because conservative assumptions were used in the
analysis, actual doses are expected to be lower.
The NNFD and LTC handle materials which could pose a risk to public
health and safety if released during accidents. Prior NRC analysis of
operation of the NNFD considered accidents including criticality, fire,
and flood (NRC, 1978). This prior analysis is supplemented by
consideration of the research and development, analytical, and
decontamination operations conducted at the LTC. The initial step in
the accident analysis is auditing of hazardous materials and
potentially hazardous activities present or conducted at the facility.
Other than radioactive materials, the LTC does not contain significant
inventories of potentially hazardous materials. In addition, the
facility does not fabricate or convert materials in any continuous
process. Thus, the handling and examination of fuel assemblies and the
management of effluents associated with these operations are the
activities which may pose a risk to the public health and safety.
The NNFD conducts an environmental monitoring program which
includes sediment, soil, vegetation, surface water, air, and
groundwater media at 20 locations on or near the facility. The program
is intended to identify trends in concentrations or accumulation of
uranium or other contaminants in the environment. Action levels have
been established for each media to provide a basis for response to
potential problems. Actions triggered by exceedance of an action level
may include resampling of the area, performance of isotopic analysis,
investigation of the source of contamination, elimination of the source
of contamination, or termination of operations pending identification
of a method for reduction of contaminant levels. Environmental
monitoring results are reviewed as part of the ALARA program.
The NRC staff has reviewed the location of the environmental
monitoring program sampling points, the frequency of sample collection,
and the trends of the sampling program results in conjunction with
environmental pathway and exposure analysis and concluded that the
monitoring program provides adequate protection of public health and
safety.
Alternatives to the Proposed Action
Implementation of the license renewal alternative involves
continued operation of the facility at levels consistent with past
practice for both the NNFD and LTC. Data and analysis presented in this
Environmental Assessment updates and supplements the data and analysis
presented in an Environmental Assessment (NRC, 1991) prepared earlier
in the license renewal process. No new major construction or
introduction of new processes is contemplated. The nature of the
manufacturing, research, and waste management operations is summarized
in this section. The system description presented in this section is
adapted from material contained in the prior B&W Environmental
Assessment (NRC, 1991) and license renewal application (B&W, 1995a).
The alternative of denial of license renewal for the B&W combined
NNFD/LTC facility at the Lynchburg, Virginia site implies cessation of
manufacturing and commencement of decontamination and decommissioning
(D&D) of the facility. Decontamination and decommissioning activities
would be substantially the same as those described for the license
renewal alternative in Section 2.1 of this environmental assessment.
However, since the fuel utilization requirements of the naval
propulsion program and the university training and research programs
would remain unchanged, selection of this alternative implies transfer
of fuel production activities to a new site.

Conclusion
The NRC staff concludes that the environmental impacts associated
with the proposed license renewal for continued operation of B&W's
NNFD/LTC facility are expected to be insignificant.
Finding of No Significant Impact
The Commission has prepared an Environmental Assessment related to
the renewal of Special Nuclear Material License SNM-42. On the basis of
the assessment, the Commission has concluded that environmental impacts
that would be created by the proposed licensing action would not be
significant and do not warrant the preparation of an Environmental
Impact Statement. Accordingly, it has been determined that a Finding of
No Significant Impact is appropriate.
