TESTE DEIN WISSEN

What is the concept of equivalent elements in the Schaeffler Diagram?

Lösung anzeigen
TESTE DEIN WISSEN

On the vertical axis of the Schaeffler Diagram, the nickel equivalent is calculated from the weight percent of austenitic forming elements like C, Ni, Mn, Cu, and N.

The chromium equivalent is calculated from the weight percent of ferritic forming elements like Cr, Si, Mo, Nb, and Ti. 

These are the key parameters that define the microstructure of the weld.

What are the six nuclear systems that make up the Generation IV reactors?

Lösung anzeigen
TESTE DEIN WISSEN

VHTR - Very High Temperature Reactor

SCWR - Supercritical Water Cooled Reactor

MSR - Molten Salt Reactor

GFR - Gas Cooled Fast Reactor

SFR - Sodium Cooled Fast Reactor

LFR - Lead Cooled Fast Reactor

TESTE DEIN WISSEN

What is the motivation for higher temperature advanced fission reactors?

Lösung anzeigen
TESTE DEIN WISSEN

Higher temperature will allow for greater efficiency in power production, can be used for hydrogen production, and can supply process heat to cities and industrial plants.

For advanced fission reactors, what is the motivation for choosing different neutron spectra?

Lösung anzeigen
TESTE DEIN WISSEN

With fast neutron absorption in fertile materials, fissile materials can be bred. Actinides are also incinerated

What are some of the benefits of fast reactors and a fully closed fuel cycle?

Lösung anzeigen
TESTE DEIN WISSEN

- significantly less U consumption

- significantly less activity after 1000 years

- less decay heat

- decreased maximum dose

What is the cost comparison of fast reactors and fully closed fuel cycles with PWRs?

Lösung anzeigen
TESTE DEIN WISSEN

The total generation cost is roughly the same if not a little more than the total generation cost for PWRs.

What are the three important crystal lattice types and some material examples?

Lösung anzeigen
TESTE DEIN WISSEN

BCC = Body Centered Cubic (e.g. Fe, V, Nb, Cr)

FCC = Face Centered Cubic (e.g. Al, Ni, Ag, Cu, Au)

HCP = Hexagonal Close Packed (e.g. Ti, Zn, Mg, Cd, Zr)

TESTE DEIN WISSEN

What are some properties of BCC lattice materials?

Lösung anzeigen
TESTE DEIN WISSEN

Ferritic steels are typically BCC structure and they have high strength and low thermal creep resistance

What is the Burgers vector for an edge dislocation?

Lösung anzeigen
TESTE DEIN WISSEN

The burgers vector represents the magnitude and direction of the lattice distortion resulting from a dislocation in a crystal lattice
