BN-1200 reactor

The BN-1200 reactor is a 1200 MW sodium-cooled fast breeder reactor project, under development by OKBM Afrikantov in Zarechny, Russia, and the design was originally planned to be complete by 2017. In 2015 Rosenergoatom postponed construction "indefinitely" to allow fuel design to be improved after more experience of operating the BN-800 reactor, and amongst cost concerns.

Goals are enhanced safety (IV generation) and a breeding ratio of 1.2 to 1.3–1.35 for mixed uranium-plutonium oxide fuel and 1.45 for nitride fuel. Based on the BN-600 reactor, the core would use greater size fuel elements and require a simplified refueling procedure compared to BN-600 and BN-800 reactor. Boron carbide would be used for in-reactor shielding. Thermal power should be nominal 2900 MW with an electric output of 1220 MW. Primary coolant temperature at the intermediate heat exchanger is 550 °C and at the steam generator 527 °C. Gross efficiency is expected to be 42%, net 39%. Safety enhancements are the elimination of outer primary circuit sodium pipelines and a passive emergency heat removal. Projected unit service life is 60 years. OKBM expects to commission the first unit with MOX fuel in 2020, then eight more to 2030. SPb AEP also claims design involvement. It is intended to be a Generation IV design and produce electricity at RUR 0.65/kWh (US 2.23 cents/kWh), and Rosenergoatom is ready to involve foreign specialists in its design, with India and China particularly mentioned. Rosatom's Science and Technology Council has approved the BN-1200 reactor for Beloyarsk, possibly to be operational about 2020. Early in 2012 Rosatom said two such units would be built there, either BN-1200 or BN-1600, along with possibly a BREST-300 unit.

Reactor

Reactor (video game)

Reactor is a raster video arcade game released in 1982 by Gottlieb. The object of the game is to cool down the reactor core without being hurled by magnetism and repulsion by enemy swarms of nuclear particles.

Reactor was developed by Tim Skelly, who was also responsible for Star Castle and Solar Quest. It was the first arcade game to credit the developer on the game's title screen.

Gameplay

The player controls a cursor that can move freely within a screen-sized arena, the nuclear reactor. The center contains a sun-type gravitational power source, the slowly overheating reactor core. The surrounding wall or the sun, if touched results in death. The cursor is controlled with a trackball by the player, who has to roll it fast in one direction in order to overcome the momentum of gravitation imposed by the sun. Swarms of enemy objects named after various radioactive particles float around in the reactor arena, obeying simple physical laws. These enemies can freely bounce into the walls at low speeds, have a repulsive force against each other and actively attack the player cursor. Boss types often break up into several smaller particles.

Reactor (software)

Reactor is a physics engine from the Irish software company Havok for use in Autodesk 3ds Max.

Overview

Reactor shipped fully integrated with 3ds max from versions 5 to 2011. In 3ds max 2012, Reactor was replaced by a PhysX-based engine called MassFX. Reactor was often used for realistic physics simulation that would be difficult or time-consuming to animate by hand.

Dynamics types

Reactor is capable of computing rigid body, soft body, cloth and rope collisions, and even all four types interacting with each other. A robust physics engine, reactor can handle several hundred rigid bodies interacting with each other without a problem on most computers. Reactor can also simulate dynamics of any supported type interacting with a water volume, including adjustable viscosity and depth, among other things.

Forces and constraints

Reactor includes a large number of forces that can be used in simulation, apart from the default gravity: springs, dashpots, motors, wind, fractures (breakable objects), even a "toy car" type, with definable body/axis/wheels. Reactor also has many constraints available, including hinges, point-to-point constraints, prismatic constraints, car-wheel constraints, point-to-path constraints, and even ragdoll constraints to realistically simulate a lifeless body. In addition, reactor is compatible with Space Warp modifiers in 3ds max.
