WRONG!
The absolute max current occurs when C is fully discharged and the sinusoidal voltage is at 170V. Given the 2 ohm thermistor resistance and 1 ohm line resistance, inductor resistance, max current is:
I = (170V - 2 * Vd) / R
I = 170V - 3V)/3ohm = 55.6A
It's impossible to achieve 86A.

You calculated the average current at 36 amps and I calculated at about 43.2 amps which is about 86.4 amps peak/instantaneous.
