I have a steam ejector and interlock (671-I-017)
to stop pulling vacuum to reactor.
Any these event happen, XV-065 opened and XV-066 opened and XV-060 opened,
it will stop pulling vacuum to reactor

As XV-060 closed (steam to ejectors - main valve)
, 677-PALL-015 actuated (MRS header pressure)
It will result that XV-061 (steam to first ejector)
, XV-062 (steam to second ejector), and XV-064 (nitrogen to adjust vacuum)
all close, PIC-065 manual, close PV-065
XV065 (vacuum line) and XV-066 (vacuum line) all close

Could any explain more detail about ejector working philosphy or physical phenomena?

Thank you very much.
