This process description addresses the process systems and equipment for the Silo 3 I
Project at the U.S. Department of Energy (DOE) Fernald Environmental Management
Project (FEMP) site. As part of the remediation of Operable Unit 4 at the FEMP,
approximately 5,100 yd3 of byproduct metal oxide materials stored in Silo 3 will be
removed (retrieval), conditioned, packaged, and transported to an off-site facility for I
treatment and/or disposal.
A separate document, Access and Retrieval Strategy for the Silo 3 Project (FEMP 2002a)
(A&RS) describes the strategy used to remove material from Silo 3. I
This process description describes the following activities:
retrieval and transfer of Silo 3 material from Pneumatic Retrieval System (PRS) and
Mechanical Retrieval Systems (MRS) to the Process Building,
0 conditioning of material,
0
packaging of material in containers, and
shipping of material off site for treatment and/or disposal.
This document describes the Silo 3 Project processes and equipment. The systems
addressed in this process description are shown in Table 1-1. Figure 1-1 is a photograph of
the silo (looking west), and Figure 1-2 is a simplified flow diagram of the entire process.
To meet as low as reasonably achievable (ALARA) guidelines regarding radiation, the
systems and equipment used to handle Silo 3 material include containment and ventilation
features to minimize exposure of personnel to both the Silo 3 material and to radon
(FEMP 2003a).
