Study Guide for Test#1
Lecture 1 (and throughout the lectures, here and there): A significant portion
of the exam will consist of definitions. These definitions will cover
all of the material covered in the course so far. Review your notes
and be able to give a credible definition of the major technical terms used
so far in the course, including (but not limited to):
 General criticality nomenclature (e.g., criticality safetyHint:
use the word "prevent", keffective, areal density, four factor
formula)
 Discrete ordinates terminology (e.g., quadrature, multigroup, diamond
difference)
 Monte Carlo terminology (e.g., random number, generations, standard
deviation, etc.)
Lecture 2: Be prepared to discuss any of the criticality physics that
we have gone over in class. Specifically:
 Be able to name three different ways of looking at keffective
 Each of the elements of MAGICMERV (Name and discuss)
 The relative importance of LEAKAGE in criticality safety
 The features of the critical mass curve (Slide 28 of Lecture 2)
 Why a low hydrogen ratio (H/X~13) actually increases the critical
mass slightly
 Why a high hydrogen ratio (H/X>1000) increases the critical
mass
Lecture 3:
 Be prepared to work a problem involving the buckling/shape conversion
method or surface density method.
Lecture 4: Be prepared to discuss:
 Advantages and disadvantages of deterministic and stochastic solution
strategies.
 How energy, space, and direction are handled in deterministic (discrete
ordinates) calculations.
 What the six steps are in the Monte Carlo life of a particle
 The three "extra" inputs that the user must provide: Number
of generations, number of histories per generation, and number of generations
skipped. (Be able to explain why we have to skip generations.)
Lecture 5: Be prepared to:
 Provide the number for any of the standards, given the name
 Define/discuss any of the definitions from the lecture
 Discuss any of the rules discussed in the lecture
 Discuss ideas from ANS 8.1. (You do NOT have to memorize the rule
numbers)
 Be able to apply Table 1 from ANS 8.1 to a particular situation to
find limits (including for contingencies)
The above will get you through 90% of the test. I reserve the right
to question you 10% about ideas from readings or class discussions
not covered by the above points.
