Karachi Nuclear Power Plant (KANUPP)


Operational Safety

KANUPP is designed with high safety provisions and its personnel maintain an effective and continuous defence against radiological hazards. The Safety features of the Plant to achieve this objective are:

  • Automatic Safety Systems -- Automatic systems safely shut down the reactor and maintain it in a safe and cooled state.

  • Normal and Emergency Heat Removal -- Heat transport systems are designed for reliable and efficient heat removal in normal operation. Provision is also made for alternative means to restore and maintain fuel cooling under accident conditions.

  • Conduct of Operation -- The Plant is operated by well qualified, trained and licensed personnel.

  • Training -- Standard programmes are followed for training and retraining of operating personnel. Training is particularly intensive for control room staff.

  • Emergency Operating Procedures -- Emergency Operating Procedures have been established, documented and Procedures approved to provide a basis for suitable operator response to any abnormal event.

  • Maintenance, Testing and Inspection -- Safety related structures, components, and systems are subject to regular preventive maintenance, inspection and testing to ensure that they meet their design intent.

  • Quality Assurance In Operation -- An Operation Quality Assurance Programme (OQAP) provides for ensuring satisfactory performance of all Plant activities related to safety.

  • Containment of Radioactive Material -- The plant is capable of retaining the bulk of radioactive material that could be released from the fuel during accident conditions.

  • Emergency Preparedness -- A "Karachi Emergency Relief Plan-KERP" has been chalked out outlining procedures for protection of public and plant personnel in the event of an accident.

  • Defence-in-Depth -- To reduce the radiation risks associated with operation of KANUPP, the station uses an approach called defence-in- depth. The concept assumes that people will make mistakes, that equipment will fail, that a designer might have overlooked something.

Defence-in-depth employs five overlapping features:

  • High Quality Station Equipment

  • Independent Safety Systems

  • Multiple Barriers

  • Continuous Fault Detection and Correction

  • High Training Standards for Plant Operation Personnel
