A nuclear reactor will produce a regular supply of energy for power plant if from the fission of U236 produces

	every radioactive product from the U236 fission itself fisOne neutron on an average from each fission causes a new fission.sions.
	more than One neutron on an average from each fission causes a new fission.
	less than one neutron released on average per fission induces new fissions.
	One neutron on an average from each fission causes a new fission.

Question 26 - For very large atoms (greater than the mass of iron) as mass increases

	binding energy per nucleon is the same
	binding energy goes up and down
	binding energy per nucleon decreases
	binding energy per nucleon increases

Question 27 - For very small atoms the binding energy per nucleon

	stays the same as mass increases.
	increases with mass.
	decreases with mass.
	does not have a regular dependence with mass.

Question 28 - When one U235 atom absorbs a neutron and splits (fissions) into two fragments how many neutrons are produced

	1-2
	2-3
	3-4
	4-5

Question 29 - The expected mass of 39K19is

	19X1.0078u+39X1.0087u
	20X1.0087u + 39X1.0078u
	19X1.0078u+20X1.0087u
	19X1.0087u+20X1.0078u

Question 30 - Why are neutrons slowed down in a fission plant.

	because U235 does not absorb slow neutrons.
	Because slow neutrons are not absorbed by U238
	because fast neutrons will result in atom bombs.
	Because U235 decays if it absorbs fast neutrons

Question 32 - How does one prevent radioactive iodine from accumulating in the system?

	taking strontium sulfate
	ingesting cesium
	taking calcium
	taking potassium iodide
