Radiation Safety Associates, Inc. has had extensive experience in
writing decommissioning plans, and performing radiological assessments and
decontamination. Some of these projects are described below:
1. University of Connecticut Health Center, Farmington, Connecticut.
Performed removal and decontamination of approximately 120 linear feet
of ventilation duct contaminated with C-14. This work was performed
in June of 1996.
2. Pratt & Whitney Manufacturing Building, Southington, Connecticut.
Performed a full decommissioning survey of this 800,000 ft2
building and decontaminated areas of residual contamination to within f
ree-release limits. Surveys included radioanalysis of wipe samples
and direct measurements for residual radioactive materials.
This work was performed between December 1995 and January 1996.
3. Pratt & Whitney Warehouse, Southington, Connecticut.
Performed a full decommissioning survey of this 324,000 ft2 building
and decontaminated areas of residual contamination to within free-release limits.
Surveys included radioanalysis of wipe samples and direct measurements for
residual radioactive materials. This work was performed between December
1995 and January 1996.
4. Mobil Technical Center, Princeton, New Jersey.
Performed a complete radiological assessment and decontamination of a
134,000 ft2 research facility for the purpose of decommissioning.
The contaminants identified at the facility were H-3, C-14, S-35 and
P-32. This work was performed from November 1995 to January of 1996.
5. Pfizer Animal Health Center, West Chester, Pennsylvania.
Performed a complete radiological assessment and decontamination of
eight buildings and a leach field at this research facility for the
purpose of decommissioning the site. The contaminants identified
at the facility were H-3, C-14, S-35 and I-125. The project was
performed from April to August of 1995.
6. Shieldalloy Metallurgical Corporation, Cambridge, Ohio.
RSA, Inc. was contracted as a subcontractor by Integrated Environmental
Management, Inc. (IEM). Provided health physics technician services
on-site for several weeks in support of a drilling operation.
The duties performed included counting air samples and calculating
results, screening samples, and performing contamination surveys.
7. University of Connecticut Health Center, Farmington, Connecticut.
Performed a radiological assessment and decontamination of a fume hood and
associated duct work. These items were contaminated with C-14. This work
was performed in February of 1995.
8. Mobil Technical Center, Princeton, New Jersey.
Performed a radiological assessment and removal of four sub-floor
piping runs contaminated with uranium. This work was performed in
September of 1994.
9. Boston University Medical Center, Boston, Massachusetts.
Performed a complete radiological assessment of this 10-story research
building and decontaminated all areas found to be in excess of the
free-release limits. The radioisotopes encountered were H-3, C-14,
S-35, I-125 and P-32.
10. Pratt & Whitney, Middletown, Connecticut.
Performed radiological assessment of Building 450, a two-story
building with associated hot cells, storage vaults, pits, and sewers
used in the 1950's and 60's by the Atomic Energy Commission (AEC)
and the Army Corps of Engineers in the Connecticut Advanced Nuclear
Engineering Laboratory (CANEL) project. The building,
unused since the end of the project, was contaminated
primarily with cobalt-60 and cesium-137. Pratt & Whitney
wished to have this building released for unrestricted occupancy
in order to turn it into a warehouse. RSA developed a decommissioning
plan which was approved by NRC, and performed the decontamination.
The project included soil and water sampling and analysis,
septic tank liquid and sludge sampling, the removal and
decontamination of more than ½ mile of underground pipe, and packaging,
shipment, and burial of all radioactive waste generated
during this decontamination effort. This building and its
environs were unconditionally released by NRC in January of 1993.
11. Pratt & Whitney Aircraft, 15 Buildings, Middletown, Connecticut.
These buildings were used in conjunction with the Atomic Energy Commission
research project described above and for machining of Thoriated-Nickel parts.
RSA performed a complete radiological assessment on each of these
structures, and the Nuclear Regulatory Commission has accepted the
results of the survey findings. No significant radioactive materials
were found during these surveys.
(Since all of the buildings on the P&W site were occupied during
the times that the surveys were taking place, a significant potential
existed for employee allegations to be made which would result in bad
publicity for one of Connecticut's largest employers. Due, at least in part,
to RSA's professionalism in carrying out these tasks, no stories
of any kind appeared in any news medium.)
12. Allied Signal, Stratford, Connecticut.
Performed a decommissioning survey of a building which had been
used for the machining of Magnesium-Thorium parts.
13. Pratt & Whitney, Manchester, Connecticut.
Performed a full decommissioning survey of this 55,000-ft2
building and decontaminated areas of residual contamination to within
release limits. Surveys included radioanalysis of soils,
building materials and ground water for natural uranium and thorium.
14. Pratt & Whitney Overhaul and Repair Building, Southington, Connecticut.
Performed a full decommissioning survey of this 506,000-ft2
facility and decontaminated areas of residual contamination to within release limits.
Surveys included radioanalysis of soils, building materials and ground water
for natural uranium and thorium.
15. Yale University, Sloane Physics Laboratory, New Haven, Connecticut.
RSA performed a radiological assessment of four fume hoods and their
associated chimney flues in Yale's Sloane Physics Laboratory in the late
summer of 1991. Based on this assessment, Yale decided that decontamination
was required. The primary contaminant was radium-226. RSA removed all
drains and piping from the hoods, removed hood liners, used abrasive
decontamination methods on remaining sections and interiors of chimney
flues, and packaged the waste for disposal.
16. Yale University, Juggs Laboratory, New Haven, Connecticut.
Radioactive materials such as tritium and sodium had been used and stored
in the Juggs Laboratory for several decades, and contamination had
accumulated over the years. RSA removed approximately 12 four-foot-
deep concrete storage cells, underground drainage pipes and their
associated components, and performed spot decontamination on wall
and floor areas. The final radiological assessment included soil sampling.
This facility decommissioning work was completed in the late
fall of 1990 and accepted by NRC.
17. 235 E. 44th Street, New York, New York. Performed radiological
assessment of 2½ story building which had been used in the 1940's
and 50's as a radium processing facility. An assessment found
substantial low-level contamination throughout the building as
well as several "hot-spots" in drainage pipes and under certain
floor areas. RSA obtained a radioactive materials license from the
State of New York Department of Labor for the purpose of
decontaminating the building. This extensive decontamination
began in the winter of 1990 and was completed in the late summer of 1991.
Decontamination activities included removal of drains and
pipes, removal of contaminated floor and ceiling tiles,
abrasive decontamination of large floor areas, spot decontamination
of wall areas, and packaging and shipment of radioactive materials
for disposal. The New York State Department of Labor performed their
verification surveys, and the building was released for unrestricted use.
The radioactive materials license, therefore, was terminated
December 18, 1991 at our request.
18. Alexion Pharmaceuticals, New Haven, Connecticut.
Surveyed laboratory areas, bench tops and fume hoods.
Successfully decontaminated identified areas to meet free-release limits.
19. Corning Clinical Laboratories, New Britain, Connecticut.
Performed decommissioning surveys in a laboratory where Iodine-125 had
been used. Located and decontaminated various areas which were
above the free-release limits.
20. Aircraft Components, Inc. Worked closely with NRC Region I
in the survey and decontamination of this facility which had been
used for the machining of Magnesium-Thorium parts. This facility had
been abandoned by the licensee. Surveyed and decontaminated this
building to within the free-release guidelines.
21. Exxon Research Center, 1900 E. Linden Avenue, Linden, New Jersey.
Performed radiological assessment surveys and decontamination of a
four-story laboratory building for the purpose of deactivating the facility
and terminating the license. Primary contaminants were tritium and uranium.
Decontamination involved cleaning of sinks, cabinets, and shelving. This work,
performed in the spring of 1986, was accepted by the Nuclear Regulatory
Commission (NRC), the building was released for unconditional occupancy,
and the license was terminated. Due to the fact that this site is no
longer in use by Exxon, no reference is available, but Region I of the
Nuclear Regulatory Commission would have records of the satisfactory decommissioning.
22. Saint Gobain/Norton, 1 New Bond Street, Worcester, Massachusetts.
Performed radiological assessment surveys and decontamination of a large
industrial building used in manufactuing of urania and thoria refractories
in the late 1950's and 60's. Decontaminated the interior of the building
to within current free-release guidelines. This project included removal
of contaminated clay sewer line exterior to the building and assessment
and remediation of contaminated soil. The building has been released
for unrestricted use by the Nuclear Regulatory Commission,
and the environmental remediation is still ongoing.
23. Bank vault in Macon, Georgia. Removed an ingot of Radium-226
from a personal safety deposit box, decontaminated and surveyed the vault area,
and performed dose calculations for various bank employees. Work was performed
"after hours" to minimize public and staff exposure.
24. Zinc recycling mill, Atlanta, Georgia. Decontamination of a zinc recycling
mill which had become extensively contaminated with depleted uranium. Facility decontaminated
and released for further use by the mill. References for any of these jobs are available on request. Please contact us for details.
