Designed to attenuate the exposure to radiation, this shield is used while
hoisting a high integrity container (HIC) containing radioactive waste to
an on-site storage container. Combined with a lid, the bell can also be used
as a temporary storage container.
|
The function of a Transfer Bell is to safely move a LLW Container/HIC from the Waste
Process Area to a Secure Environmental Container (SEC™) at the site’s
interim Storage Pad, or any similar operation. The Transfer Bell assembly consists
of two major components, the bell section and the lifting apparatus. A typical cross
section of 11” concrete encased within 1/2” steel inner outer shells
provides 2 3/4” of lead equivalent (Co60) shielding.
A similarly constructed Lid is provided to permit the Transfer Bell to be used as a
temporary storage shield. The 78” diameter and 80” height to the Lid are
usable internal dimensions suited for a nominal 200 cubic foot model, High Integrity
Container (HIC). The vibratory compacted concrete is rated 5,000-PSI compressive strength
at twenty-eight days with a density of 150 PCF. All surfaces are prepared and coated with
a two-part epoxy system.
