MED CPAPPLICATION OF NEGATIVE PRESSURE TO THE PRIMARY CIRCUIT + As a “Lower Generator”, the MED CP applies negative pressure to the primary circuit. + It allows the automatic implementation of standardised air speeds. These air speeds are configurable and continuously controlled. + Reduced radiological risk (individual and collective dose rate) - no atmospheric contamination of the reactor building OPERATING PRINCIPLE + The suctioned air is filtered by two "nuclear" absolute filters. + This air is then heated before passing through the second filtration stage to trap the radioactive iodine. + The cleaned air can be released in the reactor building or the E BA system. + A RS485 connection is available for the radioprotection station ADVANTAGES + Safety (strengthening the lines of defence) + Worry-free servicing + Simplification of activities on site : the MED CP is easy to use + Availability (control of the reactor shutdown schedule) + Security (no more spurious shutting down of the differential pressure devices) - automatic reset + Installation of the MED CP has no impact on the reactor shutdown schedule (MED CP deployment: 3 hours; likewise to remove it from the reactor building) + Reduced waste (fewer airlocks, etc.) + Financial savings: less contamination in the reactor building = fewer site evacuations The manufacturer formally reserves the right to make any modifications it considers suitable to its models.
