Subject: ALARA Center
Activities for Week of April 11, 2005
1.
PFP visited the Center looking for information on vacuum cleaners (HEPA) high
value units, scabbling tools, nibblers and the chemical decon foam
process. In some of the glove box work, PFP are not able to get access to
all the material that needs to be removed. Looked at Nilfisk vacuum
cleaners, web site: www.pa.nilfisk-advance.com
. Nilfisk has a vac unit 3997W, HEPA filtered, that draws 1442 cfm. Looked
at Trumpf nibblers, web site: www.Trumpf.com, look under
products, hand tools, enter nibbler in search. Talked about scabbling
tools, Desco tool roto-pinger unit, web site: www.descomfg.com, and also the
ICM wall walker unit that was demonstrated at the Center last week, web
site: www.icmachines.com . The foam
decon process was from EAI, web site: www.eai-inc.com, applied by
Intelagard, web site: www.intelagard.com
.
PFP held training on
glove change outs on glove boxes for four NCO's at the Center's training
area. PFP held a meeting at the Center with K-Basin personnel to
discuss use of RAD-Pro chemical process on some applications at the
Basins. The group also looked at the Intelagard foam applicator that the
Center has on loan from National Safety (See Vendor Section below for further
information), to see if the unit has application at the Basins and
PFP.
Attended meeting concerning the planned removal of Vent
Ducting in Building 291-Z at PFP. Ducting was inspected by a tractor robot
and a video tape reveals the ducting has up to 2" of an unknown substance and
activity levels of 18 million dpm/100cm2 or more. Ducting will be
surveyed using NDA and Non-Destructive Test Techniques. Plan is to
install a blank at one end and that should provide a sample for analysis.
Received info on a composite material used to shield neutrons in
containers with spent nuclear fuel or nuclear waste. Forwarded the info to
PFP Radcon Engineering. Product is called Talbor and is sold by Talon
Composites LLC who also sell Boralyn, a neutron absorbing material made from
aluminum and boron carbide. For more info, contact the ALARA Center or
http://www.taloncomposites.com/ Received call from David Sanders
who is the new Radcon Manager for Groundwater at Savannah River. He wanted
a point of contact at Hanford so referred him to Steve Landsman.
2.
K-Basins RadCon visited the Center looking for a method of draining buoyancy
cylinders on long handled basin tools. The cylinders have to be opened to
ensure all liquid is removed. K-Basins have tried to drill holes into the
stainless steel cylinders, but have encountered a number of problems. The
Center suggested taking a Unitec saw, web site: www.csunitec.com that have a pipe chain vice
for holding the cutter and cut an opening into the cylinder. If the
cylinder needs to be open to allow filling with kitty litter or grout, use the
saw to cut through the entire cylinder. More discussion is planned at the
Center on disposal of the cylinders.
3.
ALARA Center attended a tour of the (North Load out Pit) NLOP sludge
grouting equipment at the Parson's Fab Facility in Pasco. The
NLOP sludge grouting equipment is a T-Plant operation for NLOP sludge
from K-Basins. The initial equipment was built
at PNNL's PPL, then sent to Parson where modification were made to complete
the process equipment as it is today. The equipment will be disassembled
~4/19 and shipped to T-Plant. After reassembly at T-Plant, additional
checkout will continue until a system ORR will be performed in July
2005.
4. Nancy
Kirner passed along an old lessons learned from 222-S concerning CO2 Decon
of concrete. Apparently the blasting technique worked well at removing the
contamination but it was suspended in the air above the concrete creating
high concentration levels and contaminating the equipment. PFP is
looking at this technique to help with D&D.
FOR YOUR INFORMATION
1. New ALARA Contact at Los
Alamos is Julio Castro at email jcastro@lanl.gov or (505)
667-9317. Julio is in the process of obtaining tools, equipment and
material for the Los Alamos ALARA Center.
2. Operating Summary 2005-06
has an article about how a researcher damaged a radioactive source trying to
remove it from its container. See web
site: http://www.eh.doe.gov/paa/oesummary/oesummary2005/oe2005-06.pdf They tried beating it apart with a hammer and finally
used a torch. If you work with sources, this is a "must
read".
VENDOR DEMONSTRATIONS AND
VISITS
1. American Boiler Works (ABW) of
Everett, Washington will be visiting FFTF on April 18th with
specific information on the Interim Storage Casks that ABW fabricated for
Fluor for FFTF. ABW will be visiting the Center 1 PM TO
3 on the
18th for anyone interested in discussing the company
products'. Web site: www.americanboilerworks.com
2. Global Matrechs and Dow have a foam (EKOR)
that was developed at Chernobyl for encapsulation high dose
material. The presentation and demonstration is being set up
for next week (4/21/05) at Hammer (Rm 31) from 8 a.m. to noon. If your
interested stop by the Hammer facility. EKOR was presented to the Hanford
site back in 2001, then distributed by EUROTECH
LTD.
3. The Center received a decon foam application machine
from National Safety, web site: www.nationalsafetyinc.com
marketed as Intelagard Merlin Handicart foam system, web site: www.intelagard.net . This system
applies the foam for decontamination of materials like the radioactively
contaminated floor decon that was noted in the Centers weekly report of March
28, 2004, at the old Hanford ATG facility.
4. Set up a demo of the NuCut battery powered shear for
FFS. They had the vendor cut piping in a realistic mockup and the workers
were impressed. They are looking for funding. Read about this tool
at www.trutechllc.com/nucut.htm.
