Part One:

Identify the following Technical Specifications (Tech Specs) of the Chicago Pile number 1 (CP-1) reactor: 1. Thermal power in Watts(thermal), Wth. 2. Fuel material

3. Moderator material

4. Control rods material

5. Safety (Scram) material

Part Two:

List the power levels in MWth of the following reactors:

1. Chicago Pile Number 1, CP-1,

2. Graphite Reactor X-10,

3. Hanford Piles,

4. Typical modern Pressurized Water Reactor (PWR) or Boiling Water Reactor (BWR).

Part Three:

The yield from the Hiroshima device was 12.5 kT of TNT equivalent, and the yield from the Nagasaki device was 22 kT of TNT. Assume that one critical mass of lead-reflected U235 Oralloy at about 30 kgs, and one critical mass of Pu239 at about 10 kgs were used to generate these yields. Compare the energy release efficiencies of the two devices as the fraction or percentage of the weight of fissile material converted into energy in the case of the Hiroshima gun barrel concept versus the Nagasaki implosion process.
