(Note: ELM's and transients are not treated here)

*1. Nominal case (system code)*

The system code predicts an average first wall heat
flux of 0.2 MW/m^{2} to account for the 56 MW of power
radiated from the core plasma. A peaking factor of 1.25
is assumed.

*2. Nominal case including divertor radiation (LLNL calculation)*

A more detailed analysis was performed by LLNL that includes
radiation to the first wall from the divertor region. Two
cases were analyzed, and the results are copied here:

a) partially attached

b) detached

*3. Mid-plane localized heat flux*

As in ITER, we expect more severe conditions to exist for quasi-steady
timescales longer than the first wall thermal equilibration time. This
might occur for example during plasma startup. Full details of such
conditions have not been analyzed, but a reference case has been devised
with approximate peak heat flux (5 MW/m^{2}) and deposition width (0.6 m
FWHM) assuming a Gaussian distribution. That case is plotted here. The form of the equation is:
, where a=5 MW/m^{2}, b=0, c=0.25.
