RECOMMENDATION 2012–1 TO THE
SECRETARY OF ENERGY Savannah
River Site Building 235–F Safety
Pursuant to 42 U.S.C. 2286a(a)(5),
Atomic Energy Act of 1954, As
Amended
Dated: May 9, 2012
Background
The Defense Nuclear Facilities Safety
Board (Board) believes that the
Department of Energy (DOE) needs to
take action to remove and/or immobilize
the residual contamination within
Building 235–F because of the potential
dose consequences to collocated
workers and the public. Furthermore,
the Board believes that DOE must also
take near-term action to more effectively
prevent a major fire in Building 235–F.
Building 235–F at the Savannah River
Site (SRS) houses several partially
deactivated processing lines including
the Plutonium Fuel Form (PuFF)
facility, Actinide Billet Line, Plutonium
Experimental Facility, and the old
metallography lab glovebox. Building
235–F no longer has a DOE mission. It
is currently operated in a surveillance
and maintenance mode and is normally
unoccupied.
With the exception of residual
contamination, Building 235–F has been
de-inventoried of special nuclear
material. The remaining residual
contamination is the principal hazard
posed by Building 235–F and includes
a significant quantity of plutonium-238
(Pu-238). More than 95 percent of the
Pu-238 is located in the PuFF facility;
approximately 82 percent is
concentrated in 2 of the 9 PuFF facility
cells. It should be noted that the
residual Pu-238 contamination is a fine
ball-milled powder that is in a highly
dispersible form, which increases the
potential dose consequences associated
with a radiological release.

The responsible SRS contractor,
Savannah River Nuclear Solutions
(SRNS), has determined that the
unmitigated consequences of a
seismically-induced full-facility fire are
greater than 10 rem offsite and 27,000
rem to the collocated worker at 100
meters. F-Area routinely has more than
a thousand site workers who are
normally in the facilities, construction
sites, and trailers located adjacent to
Building 235–F. Some of the trailers that
house workers are located within the
Building 235–F fence line.
While DOE does not conduct any
operations within Building 235–F, fires
could start inside the building if
energized electrical equipment or wiring
failed or was damaged during a seismic
or other natural hazard event. Electrical
sparks or heat from electrical equipment
could ignite adjacent combustible
material. Two of the key preventive
controls for fire scenarios are
eliminating potential ignition sources
and controlling the amount of
combustibles. In September 2011,
during a walkdown of Building 235–F,
the Board’s staff identified a significant
quantity of transient and fixed
combustibles and unnecessary electrical
equipment that had not been air gapped.
DOE has taken action to remove the
transient combustible material and to
limit access to Building 235–F.
However, no actions are currently
planned to remove the fixed
combustibles or unneeded electrical
equipment.
In the event of a fire, Building 235–
F has several vulnerabilities. First, the
Building 235–F fire detection system is
not credited, does not provide complete
coverage, nor is the building normally
occupied; consequently, a fire could
smolder and burn undetected. Second,
Building 235–F does not have a fire
suppression system to prevent an
incipient stage fire from growing into a
room fire. Third, Building 235–F does
not have fire barriers with a qualified
fire rating to prevent the spread of a fire
to adjacent rooms. The Building 235–F
Fire Hazards Analysis notes that the
subdividing walls and floors are in
many places incomplete or penetrated
and are not adequately sealed to achieve
a qualified fire rating. In addition, some
of the existing walls contain cellulose,
which is combustible and could allow a
room fire to spread to other portions of
the building. Fourth, the absence of
standpipes or hose connections inhibits
the ability of the fire department to fight
a fire inside Building 235–F. To combat
a fire, firefighters would need to prop
open the exterior doors to allow the
passage of fire hoses; this would allow
smoke and firewater, potentially

contaminated with radioactive material,
into the environment.
The July 2011 draft of the Basis for
Interim Operations (BIO), prepared by
SRNS notes that the Building 235–F
structure can only provide limited
confinement during or following a
seismic event because seismicallyinduced building cracks may develop.
Consequently, the building structure
cannot be credited as a control to
prevent a post-seismic unfiltered
release. In 2010, DOE took action to
improve the safety posture of Building
235–F by reducing the height of the
abandoned stack located adjacent to the
building. The contractor’s structural
analysis indicated that the concrete
stack, prior to the height reduction,
could have collapsed onto Building
235–F during a seismic event causing
significant structural damage.
In addition to fires, loss of
confinement accidents could also
release radioactive material. For
instance, a release could be caused by
a breach of the confinement or the
ventilation system during a seismic
event. However, the Building 235–F
confinement ventilation system cannot
be relied upon to continue to perform its
safety function during or following a
seismic event. The draft BIO states that
non-load-bearing building elements may
fail during a Performance Category-3
seismic event, resulting in impact
damage to safety-related structures,
systems, and components such as
ventilation ducts. The draft BIO states
that the metal ventilation ducts may
leak after an earthquake because they
are not completely welded and that the
concrete roof exhaust tunnel may
develop cracks.
Loss of confinement can be caused by
degraded equipment. The deteriorated
condition of the PuFF facility was noted
in an October 1991 report by DOE’s
Office of Nuclear Safety,1 which
identified as an issue the integrity of
elastomer seals that form part of the
confinement boundaries inside Building
235–F. In addition to degradation with
age, these elastomer seals also degrade
with exposure to Pu-238. Although
identified two decades ago, this issue
remains. The cells have numerous
penetrations (e.g., glove ports, viewing
windows, ventilation supply and
exhaust, utility services). In the draft
BIO, SRNS stated that ‘‘the [elastomer]
seals around the cell and glovebox
penetrations are expected to be in a
1 U.S.
Department of Energy, 1991, Report of an
Investigation into the Deterioration of the
Plutonium Fuel Form Fabrication Facility (PuFF) at
the DOE Savannah River Site, DOE/NS–0002P,

degraded condition due to the years of
operation in a radiation environment.’’
The continued deterioration of the
elastomer seals increases the potential
for the spread of the contamination
outside of the cells. Even under normal
operations, a loss of confinement from
these cells would greatly increase the
complexity and hazard associated with
decontamination and decommissioning
of Building 235–F.
DOE conducted a small fire drill at
Building 235–F in December 2011,
which simulated a minor radiological
release. While DOE conducts periodic
drills, DOE has not conducted a
Building 235–F radiological drill
involving the adjacent Mixed Oxide
Fuel Fabrication Facility or Waste
Solidification Building construction
sites to examine how these facilities
would respond to a significant
radiological release from Building 235–
F. In the event of a significant
radiological release, the amount of
mitigation provided by sheltering in
place may not be sufficient to protect
nearby workers. This is especially true
for seismically-induced fires, since the
same seismic event may also damage
nearby trailers and administrative
buildings.
The Board has previously identified
the need to address the residual
contamination in Building 235–F. In a
June 12, 2003, letter to the Secretary of
Energy, the Board noted that the risk
associated with several hazards in
Building 235–F, including the Pu-238
residual contamination, had been
accepted rather than eliminated. The
report enclosed with the June letter
further noted that DOE should consider
decontaminating areas with residual
contamination to reduce the risk
associated with a potential release.
Since that time, DOE has on a number
of occasions evaluated options and
developed plans to address the residual
contamination. However, these efforts
have not successfully transitioned from
planning to execution, and the residual
contamination and the hazard it poses
still remain in Building 235–F.
Conclusion
The Board believes that due to the
potential dose consequences to
collocated workers and the public, it is
unacceptable for the residual
contamination within Building 235–F to
continue to remain unaddressed.
Recommendation
Given the continuing hazard posed by
Building 235–F as detailed above, the
Board recommends that DOE:
1. Take action to immobilize and/or
remove the Pu-238 that remains as
PO 00000
Frm 00025
Fmt 4703
Sfmt 4703
29987
residual contamination within Building
235–F.
2. Concurrent with subRecommendation 1, take near-term
actions and implement compensatory
measures to improve the safety posture
of Building 235–F and reduce the
potential for and severity of a
radiological release, including but not
limited to the following.
a. To the extent feasible, remove from
Building 235–F all transient and fixed
combustibles that are not directly
necessary for surveillance and
maintenance activities and ensure that
the transient combustible loading in the
facility remains as low as reasonably
achievable.
b. Ensure that all electrical equipment
not necessary to support facility safety
systems, life safety, or surveillance and
maintenance activities is de-energized
and air gapped. Remove all electrical
and support equipment remaining
within former process areas that is not
necessary for surveillance and
maintenance.
c. Evaluate the condition and
operability of early detection and alarm
systems in the PuFF facility, such as the
heat and smoke detectors (with the
exception of those located within the
PuFF facility cells, if evaluating them
would require intrusion into the cells).
Take action, as necessary, to ensure that
these systems are credited in the safety
basis, are remotely monitored, provide
reliable detection of hazards, and are
maintained in accordance with National
Fire Protection Association 72, National
Fire Protection Alarm and Signaling
Code.
3. Concurrent with subRecommendation 1, take action to
ensure that the SRS emergency response
to a radiological release from Building
235–F is adequate and effective,
including but not limited to the
following.
a. Ensure that an integrated
emergency response plan is in place that
considers the collocated workers in
facilities, construction sites, and trailers
located adjacent to Building 235–F.
Development of this plan should
include an evaluation of the specific
locations where collocated workers are
directed to shelter in place to ensure
their adequate protection during and
following a potential radiological
release from Building 235–F.
b. Ensure that periodic coordinated
drills in response to a simulated event
at Building 235–F are conducted. Such
drills should include appropriate
response actions by personnel in the
adjacent facilities and construction
sites, such as sheltering in place or
evacuating depending on proximity to

material.
The Board urges the Secretary to avail
himself of the authority under the
Atomic Energy Act (42 U.S.C. 2286d(e))
to ‘‘implement any such
recommendation (or part of any such
recommendation) before, on, or after the
date on which the Secretary transmits
the implementation plan to the Board
under this subsection.’’

\1\ U.S. Department of Energy, 1991, Report of an Investigation
into the Deterioration of the Plutonium Fuel Form Fabrication
Facility (PuFF) at the DOE Savannah River Site, DOE/NS-0002P, https://www.osti.gov/bridge/servlets/purl/6246281-tBgi3H/6246281.pdf.
---------------------------------------------------------------------------
DOE conducted a small fire drill at Building 235-F in December
2011, which simulated a minor radiological release. While DOE conducts
periodic drills, DOE has not conducted a Building 235-F radiological
drill involving the adjacent Mixed Oxide Fuel Fabrication Facility or
Waste Solidification Building construction sites to examine how these
facilities would respond to a significant radiological release from
Building 235-F. In the event of a significant radiological release, the
amount of mitigation provided by sheltering in place may not be
sufficient to protect nearby workers. This is especially true for
seismically-induced fires, since the same seismic event may also damage
nearby trailers and administrative buildings.
The Board has previously identified the need to address the
residual contamination in Building 235-F. In a June 12, 2003, letter to
the Secretary of Energy, the Board noted that the risk associated with
several hazards in Building 235-F, including the Pu-238 residual
contamination, had been accepted rather than eliminated. The report
enclosed with the June letter further noted that DOE should consider
decontaminating areas with residual contamination to reduce the risk
associated with a potential release. Since that time, DOE has on a
number of occasions evaluated options and developed plans to address
the residual contamination. However, these efforts have not
successfully transitioned from planning to execution, and the residual
contamination and the hazard it poses still remain in Building 235-F.
Conclusion
The Board believes that due to the potential dose consequences to
collocated workers and the public, it is unacceptable for the residual
contamination within Building 235-F to continue to remain unaddressed.
Recommendation
Given the continuing hazard posed by Building 235-F as detailed
above, the Board recommends that DOE:
1. Take action to immobilize and/or remove the Pu-238 that remains
as residual contamination within Building 235-F.
2. Concurrent with sub-Recommendation 1, take near-term actions and
implement compensatory measures to improve the safety posture of
Building 235-F and reduce the potential for and severity of a
radiological release, including but not limited to the following.
a. To the extent feasible, remove from Building 235-F all transient
and fixed combustibles that are not directly necessary for surveillance
and maintenance activities and ensure that the transient combustible
loading in the facility remains as low as reasonably achievable.
b. Ensure that all electrical equipment not necessary to support
facility safety systems, life safety, or surveillance and maintenance
activities is de-energized and air gapped. Remove all electrical and
support equipment remaining within former process areas that is not
necessary for surveillance and maintenance.
c. Evaluate the condition and operability of early detection and
alarm systems in the PuFF facility, such as the heat and smoke
detectors (with the exception of those located within the PuFF facility
cells, if evaluating them would require intrusion into the cells). Take
action, as necessary, to ensure that these systems are credited in the
safety basis, are remotely monitored, provide reliable detection of
hazards, and are maintained in accordance with National Fire Protection
Association 72, National Fire Protection Alarm and Signaling Code.
3. Concurrent with sub-Recommendation 1, take action to ensure that
the SRS emergency response to a radiological release from Building 235-
F is adequate and effective, including but not limited to the
following.
a. Ensure that an integrated emergency response plan is in place
that considers the collocated workers in facilities, construction
sites, and trailers located adjacent to Building 235-F. Development of
this plan should include an evaluation of the specific locations where
collocated workers are directed to shelter in place to ensure their
adequate protection during and following a potential radiological
release from Building 235-F.
b. Ensure that periodic coordinated drills in response to a
simulated event at Building 235-F are conducted. Such drills should
include appropriate response actions by personnel in the adjacent
facilities and construction sites, such as sheltering in place or
evacuating depending on proximity to

the simulated plume of radioactive material.
The Board urges the Secretary to avail himself of the authority
under the Atomic Energy Act (42 U.S.C. 2286d(e)) to ``implement any
such recommendation (or part of any such recommendation) before, on, or
after the date on which the Secretary transmits the implementation plan
to the Board under this subsection.''
