Review for Test#2
For the Chapter 2 material, you need to be able to:
- Define any of the group cross sections in notes.
- Find a group total cross section, given the flux shape and cross
section as a function of energy.
- Justify the use of Fission-1/E-Maxwellian spectrum approximations.
- Explain how resonance treatments fit into the formation of multigroup
cross sections.
- Be able how to collapse cross sections in either energy or space (or
both).
- Be able to describe the outer and inner iteration strategies--utilizing
either Jacobi orGauss-Seidel strategies for outer iterations.
For the Chapter 3 material, you need to be able to:
- Describe the basic approach of quadrature integration and perform
a simple integration with quadrature provided.
- Describe how the values and weights are found for a 1D Legendre quadrature.
- Write down and define each of the terms of the the 1D slab transport
equation
- Explain the need for an auxiliary equation.
- Describe and apply each of the 4 auxiliary equations discussed: Step,
Diamond difference, Weighted, and Characteristic. (“Apply” means
to arrive at the equations for the average flux and outgoing flux from
the incoming flux and source.)
- Describe the 1D sweeping strategy for positive and negative mu directions.
- Describe how Reflecting, Periodic, and White boundary conditions
are implemented in 1D discrete ordinates.
From the Chapter 4 material, you need to be ale to:
- Define level symmetry.
- Describe the ONE degree of freedom that level symmetry gives you.
- From a given order (N) and m1, find the N(N+2)/8 angles in the 1st
octant (each of which has a mu, an eta, and a xsi – all positive).
- Derive 2D Cartesian diamond-difference equations.
- Describe the sweep strategy for 2D Cartesian geometries.
- Describe how ray effects arise (with a simple set of diagrams).
- Describe how ray effects are dealt with
As before, this will cover 90% of the test, with the other 10% based on
creative application of the course material. |
