There's a type of resistor that's made exactly for applications like yours (pulsed, low inductance, high power): Metal film resistors in transistor packages. They can dissipate 50W or more (with appropriate heatsinking), have ultra low inductance, and are rated for very high pulse power.
Here's an example of a 2.7kOhm, 100W type: https://www.digikey.com/en/products/detail/ohmite/AP101-2K7-J/5878524
18 of them in series will do what you want, with some safety margin (1.8kW rated power dissipation). Keep in mind that cooling 1kW is not trivial.
Also, the specifications for that resistor make me suspect that you might have a very dangerous 200kV capacitor bank... Be careful.
