What are the advantages and disadvantages of fission? Advantages and disadvantages of nuclear power stations Advantages Disadvantages Produces no polluting gases. Waste is radioactive and safe disposal is very difficult and expensive. Does not contribute to global warming. Local thermal pollution from wastewater affects marine life. What are the advantages of using fission as an […]

What is Derived Air Concentration?
What is Derived Air Concentration? The concentration of a given radionuclide in air which, if breathed by the reference man for a working year of 2,000 hours under conditions of light work (with an inhalation rate of 1.2 cubic meters of air per hour), results in an intake of one annual limit on intake (ALI). […]

What do you understand by the term motion?
What do you understand by the term motion? Motion, in physics, change with time of the position or orientation of a body. Motion along a line or a curve is called translation. Motion that changes the orientation of a body is called rotation. What is the change in position of an object called? In physics, […]
How do you calculate plume rise?
How do you calculate plume rise? Solution: Calculate wind speed at stack height. u = u1 * (z/z1)p = 3 * (50/10)0.15 = 3.8 m/sec. Check for downwash: Vs / u >= 1.5 (downwash conditions need not be considered) = 20.0/3.8 = 15.237 >1.5 (therefore downwash need not be considered) Calculate plume height, Δh. Calculate […]
What is microscopic cross section?
What is microscopic cross section? The microscopic cross-section “σ” is used to characterize the probability of reaction between a neutron and an individual particle or nucleus. A neutron can have many types of interactions with a nucleus (Ragheb, 2011). What is macroscopic cross section? The macroscopic cross-section represents the effective target area of all of […]

What is needed to be increased to increase the heat transfer rate in the boiler?
What is needed to be increased to increase the heat transfer rate in the boiler? Explanation: Water velocity is required to be increased rather than gas velocities to increase the rate of heat transfer rate in the boiler, because a considerable increase in pressure is more easily produced with water than with gas. Hence, for […]
