I didn't see anyone else point this out; excuse me if someone 
did.  But 18kV MMC is not sufficient.  The capacitors should be rated 
above the peak voltage of your NST which is
SQRT(2) * NST voltage
1.414 * 15,000 = 21,210 volts.
Unless I'm wrong, your MMC should be rated at at least 22kV.  Just 
trying to help save your monet ;-)
