|---|---|---|
| Annual report on safety | Report from each nuclear installation containing a summary and an assessment of operations and safety, operating state of the installation, site-related changes, organisational structure and personnel, radiation protection, radioactive waste, radiological situation and findings from observation of the state of the art in science and technology. It contains results of systematic safety assessments and reports on the status of pending matters with ENSI, events and findings, modifications and maintenance operations. Safety reports must be submitted by 1 March the following year. | Calendar year |
| Annual report on security | Report from each nuclear installation containing key information about the installation’s security organisation, plus a summary of all security-related events that took place during the previous year. Provides information about personnel and security organisation, special activities by security corps, outsourcing of surveillance duties to external companies, findings relating to security during downtimes for maintenance and inspection operations, frequency and results of inspections and tests of security installations, failure of important security components, structural modifications, special events and findings, statistics for IDs for security personnel. Annual security reports must be classified. Security reports must be submitted by 1 March the following year. | Calendar year |
| Quarterly report | Report from the central storage installation, deep geological repositories and Paul Scherrer Institute focusing on personal doses, dosimetry of installation and site, discharge of radioactive substances with exhaust air and waste water, surveillance of the surroundings, radioactive waste, conditioning campaigns, events and findings, modifications and maintenance operations. Quarterly reports must be submitted by not later than the end of month after the reporting period. | Quarterly |
| Monthly report | Report by nuclear power plants on the operation of the installation and comparisons with previous months (trends), especially concerning operation and safety, chemistry, radiation protection, with data relating to personal dosimetry, discharge of radioactive substances, radioactive waste, events and findings, organisation, personnel and training, as well as projects, analyses, operating experience feedback, events and findings in similar installations, activities and results of maintenance tasks. Monthly reports must be submitted by not later than the end of the following month. | Monthly |
| Outage report: engineering | Report by nuclear power plants with description and evaluation of all measures important to safety, results and findings from activities during the outage. Submission: a. initial report 4 working days prior to planned restart of installation; b. complete report by not later than 3 months after restart of the installation. | With each outage |
| Outage report: radiation protection | Report of nuclear power plants on outage, with detailed information about radiation protection measurements and findings, an assessment by the operator and including proposals for additional measures to reduce doses. To be submitted not later than 3 months after restart of the installation. | With each outage |
| Outage report: physics | Report by nuclear power plants with the results and evaluation of physical reactor measurements for various output levels upon restart following the outage. Submission: a. results of zero-load and starting measurements prior to restart of installation above 5 percent nominal output; b. complete report by not later than 3 months after restart of the installation. | With each outage |
| Dosimetry report | Report by nuclear installations with details of collective doses, dose distribution, individual doses and collective work-related doses. Dosimetry reports must be submitted by 1 March the following year. | Calendar year |
| Report on surveillance of surroundings | Report of nuclear power plants, central storage installation, deep geological repositories and Paul Scherrer Institute concerning surveillance of the surroundings, with details concerning the discharge of radioactive substances, monitoring of radioactivity and direct radiation in the vicinity of the installations. This report may form part of the monthly or quarterly reports. Surveillance reports must be submitted by not later than the end of month after the reporting period. | Quarterly |
| Report on radioactive sources | Report by nuclear installations containing a list of all radioactive sources in the installation. Reports must be submitted by 1 March the following year. | Calendar year |
| Comprehensive safety review report | Report by nuclear power plants on the periodical safety review, including results and evaluation. To be submitted in accordance with the instructions of ENSI. | Every 10 years |
| Unavailability data of systems and components | Report by nuclear power plants on the date and duration of unavailability of PSA-relevant components, including description of components and brief description of the cause for the unavailability. Reports must be submitted by 1 March the following year. | Calendar year |
| List of PSA -relevant modifications to the installation | Report by nuclear power plants with a list of modifications to the installation that could be of relevance to the PSA but have not yet been incorporated into the PSA model. Reports must be submitted by 1 March the following year. | Calendar year |
