Abstract

The heat-induced, solvent-free copolymn. of styrene (I) with maleic anhydride (II) was studied on a pilot scale in a loop reactor coupled to a tube reactor. Under conditions required for the manuf. of alternating copolymers (stoichiometric ratio of I to II or excess II) rapid reaction kinetics were obsd. resulting from the Trommsdorff effect, which, with the high reaction enthalpy of .apprx.80 kJ/mol. led to thermal instabilities esp. during start-up and at low recirculating rates. This was overcome by effective reactor control. The manuf. of products with low contents of II was also demonstrated possible by employing low II concns. (4-16%) in the monomer mixt. and rapid and efficient reactant mixing. [on SciFinder (R)]

Nuclear reactor

A nuclear reactor is a device used to initiate and control a fission nuclear chain reaction or nuclear fusion reactions. Nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion. Heat from nuclear fission is passed to a working fluid (water or gas), which in turn runs through steam turbines. These either drive a ship's propellers or turn electrical generators' shafts. Nuclear generated steam in principle can be used for industrial process heat or for district heating.

Light-water reactor

The light-water reactor (LWR) is a type of thermal-neutron reactor that uses normal water, as opposed to heavy water, as both its coolant and neutron moderator; furthermore a solid form of fissile elements is used as fuel. Thermal-neutron reactors are the most common type of nuclear reactor, and light-water reactors are the most common type of thermal-neutron reactor. There are three varieties of light-water reactors: the pressurized water reactor (PWR), the boiling water reactor (BWR), and (most designs of) the supercritical water reactor (SCWR).

Integral fast reactor

The integral fast reactor (IFR, originally advanced liquid-metal reactor) is a design for a nuclear reactor using fast neutrons and no neutron moderator (a "fast" reactor). IFR would breed more fuel and is distinguished by a nuclear fuel cycle that uses reprocessing via electrorefining at the reactor site. The U.S. Department of Energy began designing an IFR in 1984 and built a prototype, the Experimental Breeder Reactor II. On April 3, 1986, two tests demonstrated the safety of the IFR concept.
