The invention discloses a mechanical seal test system for a nuclear main pump, which is characterized in that the system comprises a medium concentration control zone, an injection medium processing zone, a frame zone and a reflux medium post processing zone. A test main shaft is used as a driven component in the frame zone; the test shaft is provided with a fluid static pressure seal or a fluid dynamic pressure seal or a fluid dynamic-static pressure combined seal. In the injection medium processing zone, a seal medium flow passage located between a low pressure container and a system seal cavity is respectively provided with a high pressure pump, a high pressure buffer tank and an energy accumulator, which are connected in series with a switchable magnetic filter, an organic filtering film and used,for providing a system pressure source; in the reflux medium post processing zone, a long pipe throttling cooler with a back pressure value is arranged at an outlet of the system seal cavity.
