The core of an lmfbr consists of a square lattice of 13, 104 fuel rods that are 0.158 in in diameter, 30.5 in long, on a 0.210-in pitch. the fuel rods are 26 w/o-enriched uranium clad in 0.005-in stainless steel. liquid sodium enters the core at approximately 300°c and passes through the core at an average speed of 31.2 ft/sec. the core produces 270 mw of thermal power, with a maximum-to-average power density of 1.79. calculate: (a) the maximum heat production rate; (b) the maximum neutron flux.

Fill in the blank. the number of each type of element in the compound (other than 1) is represented by a small number to the right of the element symbol.

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.
