CRYSTAL structure has ordered, repeating ARRANGEMENT of atoms. Fibres are liable to maintain this and thus have high specific strength. As SIZE increases, the CONDITION of ordered and repeating arrangements can't be guaranteed because of several types of defects and dislocations and thus the specific strength gets lower.

For SUBSONIC flow at INLET SECTION of a diffuser a lower velocity and HIGHER pressure will exist at the exit section. For supersonic isentropic flow at the inlet section a higher velocity and lower pressure will exist at the exit but if a SHOCK wave occurs in the diffuser then a higher pressure will exist at the exit.

INCREASE in area for increase in VELOCITY for supersonic flow is required because the DENSITY decreases faster than velocity increases at supersonic speeds and to maintain continuity of MASS, area must increase.

WATER containing heavy isotopes of hydrogen (DEUTERIUM) is known as heavy water. Heavy water is USED as a MODERATOR. Heavy water has low cross section for absorption of neutrons than ordinary water. Heavy water slows down the fast neutrons and thus MODERATES the chain reaction.

Fuel CYCLE a series of sequential steps involved in supplying fuel to a nuclear power reactor. The steps include : Mining, REFINING URANIUM, fabrication of fuel elements, their use in nuclear reactor, CHEMICAL processing to recover remaining fissionable material, re-enrichment of fuel from RECOVERED material, refabrication of new fuel elements, waste storage etc.
