Factual errors: When a reactor is "SCRAM"ed it does not initiate the use of massive cooling systems. The SCRAM process is the rapid (4 second or less) insertion of the control rods into the core which shuts the reactor down by absorbing the neutrons. If the control rod SCRAM fails, then the reactor can be SCRAMed by using a neutron absorbing liquid injected into the core from pressurized tanks (no pumps.) Also, in addition to the cooling pumps, there is an Emergency Core Cooling System which injects a large amount of cooling water into the core if the primary colling system fails.
