1. Portable Reactors

Nuclear scientists all over the world devote much time to the problem of making reactors lighter and more compact than those which we have now. This is especially important for the countries with big and sparsely populated Arctic regions. To supply diesel oil to the remote Arctic station is very difficult. To provide such Arctic stations with a source of light and heat, the scientists have made the Low Power Reactor. This reactor supplies enough energy to light 300 cottages or heat 30 cottages. It is a highly specialized reactor. Instead of producing heat that goes to a turbogenerator, this reactor produces steam in its own core. The Low Power Reactor is made portable because it is intended for use at remote stations. Its components to be easily taken apart and reassembled are light in weight. It is a simple matter to fly the reactor parts to any place and then assemble them where the reactor is to be used.

2. Faster Than Light

The theoretical forecast made by the physicists on the transparency of particles and their capability to pass through each other has been confirmed on the accelerator of atomic par­ticles in Serpukhov, a town near Moscow. The accelerator made it possible to study the nature of the interrelated nuclear forces between two protons. It appears that they cause the particles to repulse one another, i. e., to act like an electric field. The physicists are of the opinion that the Serpukhov accelerator will help them to find out whether there is a possibility of the existence of a signal which could spread faster than light.
