PNRA INSPECTION POLICY Under Section 16(2)(i) of PNRA Ordinance, PNRA is responsible to inspect all nuclear installations and nuclear material to ensure that regulations concerning safety measures are properly followed. The purpose of the inspections is to make licensee aware of its ultimate responsibility The management of PNRA is committed to provide necessary resources for the inspections. The regulatory inspections cover all structures, systems, components and activities important to safety. The inspections are performed by PNRA authorized inspectors and are conducted as per approved inspection plan. The results of the inspections are documented in the form of inspection reports which form the basis for any subsequent enforcement action.

POWERS OF INSPECTOR Under Section 29 of the PNRA Ordinance, an inspector shall have the powers to: Enter any premises for the purpose of satisfying himself as to whether the provisions of the rules and regulations have been or are being adequately complied with; Examine designs, drawings, records, reports or documents; carry out any tests and investigations; obtain and analyze any samples; lock and seal any premises, nuclear installation, radiation generator, or any part thereof, where any nuclear substance or radiation generator is being used, stored, operated or maintained

PNRA INSPECTION PROGRAM FOR NUCLEAR POWER PLANTS PNRA inspection program forms the basis for inspection activities of nuclear power plants. PNRA performs regulatory inspections to ensure compliance with: national regulations, conditions attached to the license and; commitments made by the applicant/licensee for safety These inspections, however, do not relieve the licensee of its ultimate responsibility for safety The inspections of nuclear power plants are performed by respective regional Directorates in coordination with the Licensing Directorate (NSD) responsible for authorization and Licensing (NSD)

PNRA INSPECTION PROGRAM FOR NUCLEAR POWER PLANTS The inspection of equipment manufacturing is the responsibility of NSD The Regional Directorates (R-2) and R-3 located at respective nuclear power plant sites Chashma and Karachi are responsible for inspections The regional Directorate R-1 is located at Headquarters and is responsible for authorization and inspections of radiation facilities. PNRA authorized inspectors mainly conducts two types of inspections, namely planned inspections and reactive inspections. Either type of inspection may be announced or unannounced, however, announced inspections are more common. The planned inspections are conducted as per approved inspection plan and are generally announced to the licensee in advance, however, un-announced inspections may also be performed.

PLANNED INSPECTIONS are carried in accordance with a baseline inspection plan may be linked to licensee’s schedule for performing or completion of certain activities at different stages of the authorization process differ from reactive inspections in that they are scheduled in advance and are not initiated by unusual or unexpected circumstances, provide an opportunity for detailed examination of the licensee's activities to identify problems at an early stage.

REACTIVE INSPECTIONS initiated in response to an unexpected, unplanned or unusual situation or event to assess its significance and implications and the adequacy of corrective actions. may be occasioned in response to a generic problem encountered at another plant, or identified during the review and assessment process. Are conducted by employing maximum resources in case of a serious event Make use of licensee’s reports of safety related activities or event reports May involve a multidisciplinary inspection team according to the need of the situation. .

ANNOUNCED AND UNANNOUNCED INSPECTIONS In case of an announced inspection the licensee will be notified in advance by the Regional Directorate Inspections are announced when PNRA intends to observe a specific test or activity The main advantages of such inspections are: the inspector is able to discuss plans and needs with the licensee in advance, Assurances may be secured from the licensee that documentation or personnel will be available for inspection or interview Hence, announced inspections may enhance the efficiency of inspections.

METHODS OF INSPECTION Discussion and interviews with the licensee's and contractor's personnel Monitoring and direct observation (e.g. of working practices and equipment) Examination of procedures, records and other relevant documentation Tests and measurements (may be performed only in rare cases e.g. environmental radiation monitoring to verify the data of licensee) The inspectors are free to make their own judgment whether to use one or more of the above methods in a balanced way depending upon the specific situation.

AREAS OF INSPECTION The major inspection areas/activities which are included in the inspection plan are described below: Siting Construction Installation and Equipment manufacturing Commissioning Testing before fuel loading Initial fuel loading and criticality Power ascension testing Operation Decommissioning

SITING INSPECTIONS The inspection plan for siting covers the following areas/activities: Studies for determining site characteristics; Excavation and earthwork; Experiments, if any, to study dispersion models; Implementation of QAP. The applicant is required to inform about the work schedules so that PNRA inspectors may perform the inspections.

INSPECTIONS DURING CONSTRUCTION AND INSTALLATION Objective: To Verify that Construction, Installation, Manufacturing Activities are carried out in accordance with agreed codes & Standards, National& International and adequate Quality Assurance is maintained as per Quality Assurance Programs (QAP). Document to be consulted: PSAR, 50-C/SG-Q-1996 Regulatory Guide Codes & Standards (ACI, ASME, ASTM, IEEE etc) Design Specs Equipment Specs License Conditions, etc

INSPECTIONS DURING CONSTRUCTION AND INSTALLATION Control Point Inspections: Inspection carried out against selected control points from Q- plans Hold Point (H) Witness Point (W) Record Point (R) General Surveillance: To observe the working conditions and activities being taken place without any intimation and objectives as in the case of control points inspections QA Administrative Inspections: To verify overall quality assurance system of the organization of licensee and its contractors and sub-contractors

EQUIPMENT MANUFACTURING Main items/activities to be include: Processes having an effect on the quality of the equipment such as welding, etc. Qualification tests (seismic and environmental qualification), Functional tests. implementation of QAP

COMMISSIONING Control Points for inspections are selected from the Commissioning program which include hold points, witness points and record points Inspection during the commissioning stage should focus on four broad areas: Testing before fuel loading (e.g hydrostatic testing of reactor coolant system, containment integrity or leak rate testing, testing of ESF etc.) Initial fuel loading and criticality and low power testing Power ascension testing (e.g. Main coolant pump trip, loss of off- site power, turbine trip etc.) Other commissioning activities such as management of commissioning activities, modifications and maintenance, implementation of RP program etc.

OPERATION The areas to be inspected during operation phase include: Operational limits and conditions Operating procedures Control room visits Radiological protection Operator training and competence Effluent and radioactive waste management Emergency Response Planning and Procedure Refueling On-site fuel handling and storage

PROVISION OF GUIDANCE TO INSPECTORS Written procedures which ensure that all nuclear installations are inspected on the basis of a common standard and consistency in the level of safety Training program of the inspectors emphasizing upon: legal basis of inspection and the extent of inspector's authority. applicable regulatory requirements, regulations, guides and industrial standards. Inspection Program Policies of PNRA that may affect inspection Standards of conduct of inspectors The importance of objectivity and fairness on the part of inspectors and need to respect appropriate facility rules established by the licensee.
