Well, just keep in mind that the pressurizer is initially at ~650F (saturated at 2200 psia) and you said the hot leg is at 600F, so: when the RCS heats up by 10F you will be pushing 600F water into the bottom of the 650F pressurizer. So... the overall pressurizer liquid doesn't heat up (in fact, in an actual reactor the heaters will come on if pressurizer level is rising, to try and keep it saturated).
