Brief history of PNRA
• 1984:
Establishment of Directorate of Nuclear
Safety & Radiation Protection (DNSRP)
• 1994:
Creation of Pakistan Nuclear Regulatory
Board (PNRB)
(partial compliance of Nuclear Safety Convention)
• 2001:
Establishment of Pakistan Nuclear
Regulatory Authority (PNRA) with the
Promulgation of PNRA Ordinance
(full compliance with Nuclear Safety Convention)
3
Mission of PNRA
To ensure safe operation of nuclear facilities and to
protect radiation workers, general public and the
environment from the harmful effects of radiation by
formulating and implementing effective regulations
and building a relationship of trust with the licensees
and maintain transparency in its actions and
decisions.
4
Functions of PNRA
• Licensing of Nuclear Installations and Radiation
Facilities
• Safety Review and Assessment
• Regulatory surveillance and Inspections
• Physical Protection of nuclear facilities and materials
• Preparation of Regulations, Guidelines, Standards and
Licensing Procedures
• Implementation and Enforcement of PNRA
Regulations
• Liaison with International Agencies like, IAEA

Radiological Accident/Emergency
(definitions)
Accident [Safety Standards Series, Glossary]:
“Any unintended event including operating errors,
equipment failures or other mishaps, the
consequences or potential consequences of which
are not negligible from the point of view of
protection and safety.”
Emergency [Safety Standards Series, Glossary]
• A non-routine situation or event that necessitates
prompt action, primarily to mitigate a hazard or
adverse consequences for human health and safety,
7
quality of life, property or the environment.
Radiological Accident/Emergency
(definitions)
Radiological Accident/Emergency
• A situation in which there is an unintentional
exposure to ionizing radiation or radioactive
contamination
• Exposure may be real or suspected
8
Why Radiological Emergency?
• The use of sources of radiation is growing rapidly
• Emergencies involving radiation sources occur
more frequently than reactor emergencies
– Unlike reactor emergencies, the impact is
generally limited to a small number of people
– But the risk of deterministic effects is high
RISK is measured in terms of likelihood and
consequences
Types of Radiological Emergencies
• Radiological emergencies
can be grouped into four
major types
1. Facility emergencies
2. Transport emergencies
3. Severe overexposure or
contamination emergencies
4. Terrorist threats or criminal
activities
Where Radiological Emergencies Can Occur?
• Almost anywhere
– Nuclear installations
– Medical and industrial sector
– Radiography site (gamma radiography sources)
– Terrorist or criminal activities
– Illicit trafficking
– In scrap yards (wrongly disposed source)
– Research institutes

PNRA Obligation
The Authority shall ensure, co-ordinate and
enforce preparation of emergency plans for
actions to be taken following foreseeable types
of nuclear incidents that might affect the public
(PNRA Ordinance 2001 Section 39)
Ensure

Enforce
19
Regulatory Requirements
Ensure
Coordinate
Enforce
• National Regulations on Management of a Nuclear
or Radiological Emergency (PAK/914)
– Require emergency preparedness and response
arrangements from the licencee
– Implementability of emergency arrangements to be
demonstrated on regular basis
– The Authority reviews and approves emergency plans
20
National Radiation Emergency
Coordination Center (NRECC)
Ensure
Coordinate
Enforce
• To coordinate nuclear or radiological emergencies
“National Radiation Emergency Coordination CenterNRECC” is established at PNRA HQ
• NRECC coordinates with
– Licensees
– Governmental authorities/organizations
– IAEA under the conventions

Nuclear Security Emergency Coordination
Center (NuSECC)
• Focal point for the coordination with the first
responders, front line offices, law enforcing
agencies, local governments and PNRA Regional
Offices.
• Network of six emergency response mobile labs at
each Directorate/Inspectorate
• Response team (s) will be able to reach for expert
opinion within 4 to 6 hours in the major cities of
the country.
• Round the clock manning through:
Toll Free Number: 0800 777 66
25
Trainings and Public Awareness
• Arrange National/International training courses,
workshops, seminars, tutorials, Tabletop exercises
• Arrange lectures in universities/institutes of the
country
• Launched media campaign
• Distribute pamphlets/ brochures for public awareness
• PNRA conducted seminars on handling and
management of contaminated and exposed
individuals.
• Planning for national level of emergency exercise

Summary
• Sole responsibility for management of a nuclear
accident or radiological emergency situation lies with
the licensee.
• PNRA facilitates the exchange of information between
PNRA licensee, public authorities and relevant
international organizations with the aim to diminish
consequences to property, environment and public.
• PNRA coordinate and ensures the emergency
preparedness at radiation and nuclear facilities
• Improve preparedness and response capabilities of
response organization through drills and exercises
• Provision of information to general public regarding
radiation and radiation hazards.
