For a spherical thermal reactor with a water moderator in a
homogeneous mixture, what is the value of the infinite
multiplication factor necessary for the reactor to be critical? The
radius of the reactor is 1 m.
Solutions
Expert Solution
hence
determine the value of infinite multiplication factor for r=1m.
Find the correlation that gives the critical state of the
homogeneous spherical reactor with "diffusion effect cross section
∑s" and "fission effect cross section ∑f",
"diffusion coefficient D" and radius R.
Calculate the critical radius of the core of a
spherical thermal reactor moderated by graphite both with and
without (bare) an infinite reflector of graphite to show reflector
savings. The reactor (at room temp.) is fueled with 235U at a
concentration of 4.0 x 10-4 gm/cm3
A large cubic thermal reactor, moderated and reflected by an
infinite reflector of water, is fueled with
235U at a concentration of (10)^-4 g/cm3.
(a) Calculate the critical dimensions of the core.
(b) Compute the critical dimensions if the reactor is bare.
Assume that the system is at room temperature.
Consider the following question and answer.
Give an example of a homogeneous mixture: "WATER, because it is
made up of two different elements - hydrogen and oxygen, and the
comeposition is even throughout."
Which aspect of the students answer are correct? Which are
incorrect?

Classify each substance as an element, a compound, a homogeneous mixture, or a heterogeneous mixture. Element Compound Homogeneous mixture Heterogeneous mixture Answer BankAnswer BankClassify the phrases pertaining to pure substances and mixtures as either true or false. True False Components of a homogeneous mixture are visibly distinct. The components of homogeneous and heterogeneous mixtures cannot be separated, Heterogeneous mixtures contain more than one part, and each part has its own properties. Homogeneous mixtures have uniform properties throughout Pure substances only contain one type of substance and...
Compute the thermal utilization factor for a nuclear reactor
core where there are 50 moles of heavy water per mole of 5%
enriched uranium monocarbide (UC). What would be the value if light
water replaced heavy water?
A nuclear power reactor produces 3GW of thermal power from the
fission of 235U for a period of 10 weeks and then it is shut down.
Note: All numerical answers are expected with 3 significant
figures. (a) Assuming 78% of the 200MeV released per fission event
is converted to heat, estimate the number of 235U nuclei fissioned
over the 10 week period. (b) 6 % of the 235U fission events produce
as a fission fragment some radioactive nuclide X (e.g....
