In a certain thermal reactor, for every 100 neutrons emitted from fission, 10 get absorbed in fuel while still “fast” and 40 get absorbed in fuel after becoming “thermal.” The other 50 either leak or get absorbed in non-fuel materials. η T is 2.0 and ηF is 1.5 . [5] a) Calculate the multiplication factor (k) if sufficient information is given. [5] b) Calculate the resonance-escape probability if sufficient information is given. [5] c) Given that 20 of the 100...

A fuel cell is an electrochemical device that reacts hydrogen with oxygen from the air to produce water and DC electricity. A proposed application is replacement of the gasoline-fueled internal combustion engine in an automobile with a 100 kW fuel cell. You are on a summer internship with a gas supplier planning to transport hydrogen to service stations for the use in cars powered by fuel cells. The hydrogen is to be transported in tube trailers, each of which has...

Reliance on solid biomass fuel for cooking and heating exposes many children from developing countries to high levels of indoor air pollution. An article presented information on various pulmonary characteristics in samples of children whose households in India used either biomass fuel or liquefied petroleum gas (LPG). For the 754 children in biomass households, the sample mean peak expiratory flow (a person's maximum speed of expiration) was 3.2 V/s, and the sample standard deviation was 1.2. For the 753 children...
