The Pebble Bed Modular Reactor. The Pebble Bed Modular Reactor (PBMR), like most new reactor ideas, is a reincarnation of an old reactor idea. In this case the old idea is the "high temperature gas reactor" or HTGR, that then was proposed in a modular version, known as the MHTGR. The PBMR is a variant of the HTGR.
THE SOLUTION. The pebble crushing system was also dynamically controlled to cater for the variable feed by running the crusher at variable speeds from a VFD – this was a first for a pebble crushing application. To overcome the lack of drawings of the existing plant, Halyard utilized point cloud technology to survey the area to ensure new equipment and concrete works will not clash with ...
