The Pakistan Nuclear Regulatory Authorityپاکستان نیوکلیئر ریگولیٹری اتھارٹى; (PNRA), is mandated by the Government of Pakistan to regulate the use of nuclear energy, radioactive sources and ionizing radiation. The mission of PNRA is to protect the public, radiation workers and environment from the harmful effects of ionizing radiation by formulating and implementing effective regulations, building a relationship of trust with licensees, and maintaining transparency in its actions and decisions. The concept of nuclear regulation existed in 1965 but it only gained full government commission in 2001, with the establishment of the Nuclear Command Authority. The agency was established in 2001 after the President of Pakistan Justice (retired) Rafiq Tarar signed the executive decree, 'Pakistan Nuclear Regulatory Authority Ordinance No.III' in 2000. PNRA opened its operations in 2001 and is headquartered in Islamabad. History The nuclear regulatory infrastructure has been in place since 1965, when the Pakistan Research Reactor was commissioned. Established by Pakistani scientists, the regulatory regime was significantly improved when, in 1971, the Karachi Nuclear Power Plant was commissioned. Since then, the Pakistan Atomic Energy Commission (PAEC) established the nuclear safety and licensing division at PAEC Headquarters as the de facto regulatory body. The Nuclear Regulatory Authority was upgraded to 'Directorate of Nuclear Safety and Radiation Protection' (DNSRP) after the promulgation of the Pakistan Nuclear Safety and Radiation Protection Ordinance 1984 by Presidential Order. In 1994, Pakistan signed the international Convention on Nuclear Safety. As part of the convention, the Directorate of Nuclear Safety and Radiation Protection became part of the Government of Pakistan's federal agencies. It was to establish an independent nuclear regulatory body entrusted with the implementation of the legislative and regulatory framework governing nuclear power in Pakistan, radiation use in the country, and to separate regulatory functions from the promotional aspects of Pakistan's nuclear programme. In 1995, (immediately after signing the Nuclear Convention) the Pakistan Atomic Energy Commission (PAEC) had established the Pakistan Nuclear Regulatory Board (PNRB) within itself. PNRB was established to oversee regulatory affairs. Complete separation of promotion and regulatory functions and responsibilities was achieved in 2001, when the President of Pakistan promulgated the Pakistan Nuclear Regulatory Authority Ordinance No.III of 2001. Consequently, the Pakistan Nuclear Regulatory Authority (PNRA) was created, dissolving PNRB, and the Directorate of Nuclear Safety and Radiation Protection. The first chairman of PNRA was Jamshed Azim Hashmi who headed the authority till 2009. In 2009, the chairmanship was transferred to
