I'm looking at a Siemens PW1224L1200CU Main Lug Load Center. Will either the 200-amp branch breaker QN2200 or QN2200R fit into this panel? I looked at the wiring diagram but was unsure if a QN2200R breaker is considered a 'QNR' type.

The panel can indeed support a 240V breaker. The question you should ask is, is there space in the panel to physically accommodate additional breakers?
Based on the model number, your panel should look something like this.
Notice how this example image has lots of blank spaces. In a panel like this, there's no problem at all installing a new breaker (or double pole breaker in your case). However, it's not likely your panel looks like this. More probable, is your panel has all or nearly all the slots full.
If there are not two free spaces in the panel, you'll not be able to install a new breaker in this panel. You have a few options in this case.
- Install tandem breakers where possible to free up slots.
- Install a subpanel.
The other problem you could have, is that your current service will not handle the additional load. This panel can handle 100 amperes, but that does not mean you have 100 amp service. You'll have to check with the local utility to determine the size of the current service. If
Lastly, the panel might already be close to being overloaded. If you have all electric appliances (Range, Dryer, heat, water heater, etc.), adding a hot tub could cause the main breaker to trip from time to time. This will completely depend on your current consumption of power, which is not possible to know based on the information you've provided.
tl;dr
Contact a local licensed Electrician to determine what's required with installing a hot tub.
Your 200 amp service can supply your 150 amp water heater. But will anything else in your house require power at the same time? Such as a microwave, room or house heater, room or house air conditioner, stove or oven? Have you considered using the 24 instead of the 36?

Use the QN2200R (or a Q2200B)
The QN2200R is what is called out by Siemens for horizontal applications in loadcenters and some meter mains, as well as the occasional vertical application with the lugs up. The QN2200, OTOH, is what is typically used in meter-mains that mount the breakers with the handles horizontal, as it provides the correct handle orientation for a vertically mounted breaker in that configuration when the lugs are pointed down (up being ON, down being OFF).
If you don't want to deal with this, there is also a 1x4 double frame breaker in the Siemens catalog, namely the Siemens Q2200B.
