A: compagnia aerea AIR-ONE
Egregio Dr. Mauro D'Angelo,
facendo riferimento alla telefonata odierna, Le sarei grato se
potesse rispondere a questa serie di domande che ho
inviato anche a varie altre compagnie aeree.
1) Esistono nella Vs. flotta aerei appesantiti con Uranio 238?
(tipo 747 e DC10)
2) Non ritiene, la Vs. compagnia, di informarne il pubblico?
3) Se l'uso di quest'Uranio non è pericoloso, perché è in
atto una operazione di copertura su vasta scala ed anche
i vigili del fuoco degli aeroporti si rifiutano di fornire
informazioni?
4) Lei mi dice di non essere informato sull'argomento, pensa
che non sarebbe un diritto del personale di bordo sapere su
che cosa stanno volando?
5) Dati ufficiali parlano del 4% di dispersione annuale di Uranio
nell'aria da parte di aerei che lo usano come zavorra (ballast), solo
nel caso del Boeing 747, 550 aerei hanno qualcosa come 200 tonnellate
si uranio a bordo e ne rilasciano circa 8 tonnellate all'anno nell'aria.
I medici dicono che le particelle
sospese finiscono nei polmoni e nei reni e diventano causa di tumori di
vario tipo e leucemie. Non ritiene che sia preoccupante?
Cordiali saluti in attesa delle risposte.

Boeing Company Request Concerning Depleted Uranium
Counterweights
HPPOS-206 PDR-9111210356
Title: Boeing Company Request Concerning Depleted Uranium
Counterweights
See the letter from G. H. Cunningham to W. E. Morgan dated
April 14, 1983, and the incoming requests from W. E. Morgan
(Boeing Company) dated March 18, 1983 and January 6, 1983.
The Boeing Company's proposal to apply a corrosive
preventive compound to depleted uranium (DU) counterweights
was not considered "... chemical, physical, or
metallurgical treatment or process ..." and was appropriate
for exemption under 10 CFR 40.13 (c) (5).
The 747 airplane program utilized DU weights for mass
balance of outboard elevator and upper rudder assemblies on
the first 550 aircraft built. This equates to
approximately 12,000 cast parts and a total mass of DU in
excess of 200 tons. Depending upon the model, each
aircraft had either 21 or 31 weights. At each major
aircraft overhaul (about 4 to 5 years), it was anticipated
that over 20% of these weights would be corroded to where
they required reprocessing. This condition was considered
to present an unnecessary maintenance burden on the 747
operators. Aside from the high corrosion rate, the weights
were extremely difficult to transport with only one
recognized reprocessing source in the world.
In a letter dated January 6, 1983, the Boeing Company
proposed originally to apply an additional protective
coating of Cosmoline (MIL-C-11796) over the protective
coating of undamaged DU weights. They intended to require
that the weights be (1) corrosion free, (2) properly nickel
and cadmium plated and painted, (3) heated to 150-160øF,
(4) dipped in MIL-C-11796 at the same temperature, and (5)
cooled to ambient temperature. The weights in question
were exempt items manufactured by NL Industries of Albany,
New York. When the weights were reinstalled on the
airplane, they intended to fill the attachment holes with
MIL-G-23827 grease. Cautionary marking on the weights
would be kept free of corrosion preventative compounds.
They asked if these additional processes in any way
violated the conditions of 10 CFR 40 of the NRC rules and
regulations.
It was NRC staff's view that the above processing falls
within the prohibition of 10 CFR 40.13 (c) (5) (iv). That
provision states clearly that the exemption from licensing
in 10 CFR 40.13 (c) (5) for DU weights does not authorize
any treatment or processing of the counterweights except
for repair or restoration of any existing plating or
covering. This has been the regulatory position for over
20 years [see 25 FR 6427]. The above proposal involved the
processing of the DU weights to add a new coating of a
different material. If the work was performed at the
Washington plant, Boeing would need (1) a license from the
State of Washington authorizing the procedure for coating
the DU weights in its possession, and (2) a license from
the NRC to distribute the weights to exempt persons (i.e.,
the operators of the aircraft) after being coated [see 10
CFR 40.13 (c) (5) (i) and 150.15 (a) (6)].
In a second letter dated March 18, 1983, the Boeing Company
proposed the application of corrosion preventative compound
MIL-C-16173 to DU weights in service. This procedure would
be accomplished during operators scheduled maintenance
programs. It would be required that the weights be
corrosion free and finished per drawing (nickel and cadmium
plus primer) prior to brush application of MIL-C-16173.
Both MIL-C-16173 and weights would be at ambient
temperatures during application. Attachment holes would be
filled with grease (MIL-G-23827) to eliminate water traps
and cautionary markings on the weights would be kept
legible. No chemical interactions would occur between the
corrosive preventative compound (MIL-C-16173) or the grease
(MIL-G-23827) and the plating or paint because these
compounds do not contain solvents or other agents which
might soften paint. The Boeing Company believed that this
process, while not as effective in preventing corrosion as
their previous proposal, would be a significant improvement
and did not violate the intentions of 10 CFR Part 40 of the
NRC rules and regulations.
It was NRC staff view that the second proposal was not
considered as "... chemical, physical, or metallurgical
treatment or process ..." and was appropriate for exemption
under 10 CFR 40.13 (c) (5).

AIRCRAFT COUNTERWEIGHTS
Starmet CMI operates the only Federal Aviation Administration (FAA)
approved facility in the United States licensed to repair DU aircraft
counterweights.
Wide body aircraft such as the Boeing 747, Lockheed L-1011, McDonnell
Douglas DC-10 and Lockheed military C-130 all require the use of
counter-balance weights for proper flight control. The counter-balance
weights are needed on control surfaces such as ailerons and elevators.
These control surfaces have insufficient surface clearance and
area to accommodate lighter counter-weight materials. The high density
of DU makes it ideally suited for this application. Although DU is a
toxic heavy material similar to tungsten,
it is completely isolated by our plating and coating process.
Starmet CMI can provide both new and refurbished DU counterweights:
Refurbished Counterweights
Normal operational use (exposure to weather conditions) requires
periodic maintenance of DU counterweights. We have a complete
refurbishing operation that:
Guarantees quick turnaround: expedited processing on request
Reduces inventories: we offer storage with overnight delivery to
meet your repair schedules Offers substantial cost savings over
purchasing a new part Can replace irreparable parts from float
inventory at no extra charge (subject to availability)
New Counterweights
In addition to our refurbishing capabilities, our foundry operation
can manufacture new DU counterweights to customers specifications.
Radiation Shielding
Starmet has been a long time supplier of radiation shielding
products to the hospital, radiography, and commercial energy
industries. We have the experience to design and manufacture
radiation shields that are safe and reliable. Our products are
routinely used for collimation and control of radiation sources in
angiographic imaging systems, linear accelerators and
cobalt irradiation equipment employed in cancer therapy.
Military Ordnance
Starmet's low cost DU manufacturing capabilities make it one of the
leading suppliers of low cost ammunition for U.S. government weapons
systems. Our anti-armor tank penetrator munitions helped bring a quick
conclusion to the Desert Storm conflict.
