RBMK - Wikipedia
The RBMK was the culmination of the Soviet nuclear power program to produce a water-cooled power reactor with dual-use potential based on their graphite-moderated plutonium production military reactors.
Graphite-moderated reactor - Wikipedia
A graphite-moderated reactor is a nuclear reactor that uses carbon as a neutron moderator, which allows natural uranium to be used as nuclear fuel. The first artificial nuclear reactor, the Chicago Pile-1 , used nuclear graphite as a moderator.
Graphite Reactor | ORNL
The Graphite Reactor, designed for this second purpose, was built in only nine months. Its job was to show that plutonium could be extracted from irradiated uranium slugs, and its first major challenge was to produce a self-sustaining chain reaction.
This paper addresses the evaluation of RBMK graphite stack life-time. It is the practice in Russia to evaluate the reliability of the channel reactor graphite stack using at least three criteria: degradation of physical-mechanical properties of graphite, preservation of the graphite brick integrity, and degradation of the graphite stack as a ...

In the reactor core boronated graphite is sometimes used as a high-temperature control-rod material. Recent designs for gas-cooled reactors employ graphite sleeves that support the fuel elements and channel the coolant. Graphite is useful as …
Experimental opportunities and main results of the impulse graphite ...
Mar 1, 2023 · The paper presents main technical characteristics of the Impulse Graphite Reactor (IGR), which determine its unique experimental opportunities to research behavior of the fuel rods and fuel assemblies in transient and accident operation conditions.
The graphite reactor stack consists of graphite blocks stacked to provide a central region for fuel loading and an outer region for a neutron reflector. Total mass of graphite in the reactor cores was about 900 tones. For sampling from the stacks, the special technology was applied. Using the tool
The temperature field in the graphite stack primarily depends on the reactor power. The nitrogen content in the nitrogen-helium mixture (hereinafter, the sweep gas composition) affects the graphite temperature as well. The graphite stack temperature is one of the main parameters that limit the RBMK reactor operation.
Calculation and Experimental Study of the Interaction Between a …
Oct 20, 2023 · For the possible operation of power units with the RBMK-1000 reactor during the period of the formation of a graphite stack, NIKIET performed a series of experiments to recreate the force action of the graphite stack on the sealed vessel of …
Understanding Graphite Nuclear Reactor: A Compressive Guide
Oct 4, 2024 · Graphite for nuclear reactors, also nuclear-grade graphite, is made to meet the rigorous requirements of nuclear environments. When used in reactor cores, graphite primarily functions as a neutron moderator and also as part of the core’s structural material.
