Safe New Generation Nuclear Power? The Pebble Bed Modular ...

A Pebble Bed Modular Reactor (PBMR) is quite different. Instead of fuel rods, it has 452 000 pebbles. Three quarters of these are fuel pebbles, made of microspheres just under a millimetre in diameter. Each microsphere has a core of enriched uranium, about half a millimetre across, surrounded by three layers of coating: first pyrolytic carbon (a form of graphite), then silicon carbide, and ...

The Pebble Bed Modular Reactor

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.

Comparison of Two Models for a Pebble Bed Modular Reactor ...

The Pebble Bed Modular Reactor (PBMR) plant is a promising concept for inherently safe nuclear power generation. This paper presents two dynamic models for the core of a High Temperature Reactor (HTR) power plant with a helium gas turbine. Both the PBMR and its power conversion unit (PCU) based on a threeshaft, closed cycle, recuperative, intercooled Brayton cycle have been modeled with the ...
