Production of an economic high-density concrete for shielding megavoltage radiotherapy rooms and nuclear reactors

Background: In megavoltage radiotherapy rooms, ordinary concrete is usually used due to its low construction costs, although higher density concrete are sometimes used, as well. The use of high-density concrete decreases the required thickness of the concrete barrier hence, its disadvantage is its high cost. In a nuclear reactor, neutron radiation is the most difficult to shield. A method for p...

Anticoking Coatings for High Temperature Petrochemical Reactors

Ñ Anticoking Coatings for High Temperature Petrochemical Reactors Ñ Coke deposition is a major problem for several refinery and petrochemical processes, among which steam cracking for ethylene production. Decreasing coking rates will reduce decoking frequency and will also decrease heat transfer degradation. For these processes, a means of reducing coking phenomena is the application of anticok...

Safety of Nuclear Reactors

Nuclear reactors have, during the first twenty years of their existence, achieved an impressive safety record, possibly exceeding that of any comparable industry. As revealed in apaper byHenriB. Smets of the European Nuclear Energy Agency, there have been recorded during this period of time but six fatalities and less than 30 persons seriously irradiated from reactor accidents. Three of the fat...

Nuclear Weapons and Nuclear Reactors

This report addresses the tenuous link between nuclear power reactor development and the proliferation of nuclear weapons, particularly with respect to possible terrorist exploitation. Arguments are presented that contradict the popular image of nuclear weaponry as a "basement project". 4 CONTENTS
