Honors

We will be spending the next three days on projects. You will also have a large assignment on your project over the break.

Your assignment for Monday is:

All re-read the relevant sections of the European power plant report. This means the summary and whatever annexes apply to your specialty.

Plasma and blanket groups have some real meat to digest right in the report. Plasma group, identify density (number of fuel nuclei per m cubed), volume of plasma and confinement time. Start to understand energy and particle loss mechanisms.

Heating group should go back to the ITER website and be clear on power, energy, currents, type of ions, etc. You should also be clear on microwave heating including the ion and electron cyclotron frequencies and powers produced for ITER.

Magnet group. Make sure you understand the directions and purposes of the OH, Toroidal , and Poloidal fields and the configuration of the coils that produce them.

Read these notes [don't panic we will go over them in class]:

Plasma group read the above notes also.

Thermo group. Read this

and then look in text to understand thermal conduction. Heat must be transferred from lithium to water/steam by passing through tubes containing the water/steam that are immersed in the lithium. Find the equation for this heat transport and figure out the following: assume the tube wall is 1 cm thick. Assume the temperature difference between the water/ steam and the lithium is about 200 C. How many square meters of surface area are required to transport 2.5 E9 Watts of thermal power. Look up Rankine cycle and steam turbines. Identify 4 web pages that will help you design your turbine cycle.

Generator group: read text on magnetic fields and magnetic induction. Know Faraday's Law and what it means. If the changing field goes from +B to-B in 1/120 th of a second, and the coils that the voltage is being induced in have 100 turns and a coil area of 2 m square, what is the required value of magnetic field strength B to produce 20,000 V in the coil. The coil will be wrapped around soft iron so mu is not mu 0, its about 1000 mu 0 ( mu is the greek letter that looks like a fancy u).
