Lithium intercalation in porous carbon anodes (open access)

Lithium intercalation in porous carbon anodes

Carbon foams derived from the phase separation of polyacrylonitrile/solvent mixtures were investigated as lithium intercalation anodes for rechargeable lithium-ion batteries. The carbon foams have a bulk density of 0.35--0.5 g/cm{sup 3}, low surface area (< 50 m{sup 2}/g), and an average cell size of 5--10 {mu}m. Polyacrylonitrile-based carbon foams doped with phosphoric acid had capacity as high as 450 mAh/g. Carbon capacity increased with increasing phosphoric acid concentration in the doping solution. The doped porous carbon anodes exhibited good cyclability and excellent coulombic efficiency.

Packaging design criteria, transfer and disposal of 102-AP mixer pump (open access)

Packaging design criteria, transfer and disposal of 102-AP mixer pump

A mixer pump installed in storage tank 241-AP-102 (102-AP) has failed. This pump is referred to as the 102-AP mixer pump (APMP). The APMP will be removed from 102-AP 1 and a new pump will be installed. The main purpose of the Packaging Design Criteria (PDC) is to establish criteria necessary to design and fabricate a shipping container for the transfer and storage of the APMP from 102-AP. The PDC will be used as a guide to develop a Safety Evaluation for Packaging (SEP).

Seismic qualification of a switch box (open access)

Seismic qualification of a switch box

This supporting document details the results of a seismic analysis on a switch box assembly. The switch box is mounted to a Unistrut frame and is attached to the concrete floor in the 225B Building with Hilti Kwik bolts. The assembly was found to meet safety class 3 requirement. Although all components analyzed were found to be structurally adequate, some changes are recommended. To comply with SDC 4.2 specification, the Hilti Kwik bolts should be: placed at least 8 1/4 inches from the edge of the concrete floor; should have a minimum spacing of 8 inches from any Kwik bolt; and should be embedded 5 1/2 inches into the concrete. The minimum embedment distance is 2 3/4 inches. Furthermore, when the bolts are installed, rebar within the concrete should not be cut or damaged. Finally, the length of the Hilti Kwik bolt should be sized such that the distance from the top of the bolt to the top of the nut is not less than 2 thread pitches, and not more that 3/4 inch.
