The basic approach in the use of nuclear energy is to make continuous improvements in processes, organisation of activities, training of personnel and the implementation of necessary technical improvements.
There were no operational events recorded in 2015 rated as level 1 on the International Nuclear Events Scale (INES), i.e. events with a low potential impact on safety.
In 2015 there was no operational event connected with automatic reactor scram actuated by automatic protection 1.
Slovenské elektrárne complies with requirements for the protection of people and the environment against radiation and its effects, including means for ensuring such protection.
The ALARA principle (As Low As Reasonably Achievable) is the basic principle for the management of the radiation exposure of staff and workers, the production of radioactive waste and the release of the radioactive substances into the environment. Personal doses of SE staff and contractors are significantly below radiation limits. In line with applicable legislation, only those activities leading to irradiation of personnel or population are permitted, which are justified. SE achieves an excellent record for radiation protection on the long-.term basis.
As demonstrated in the following chart, the effective collective dose for Slovenské elektrárne staff and contractors exposed to radiation is very low, the Slovak units are in the world top ten for pressurised water reactor operators.
Last year there was not even one case in which the individual personnel dose limits were exceeded. There was no radiation incident or accident. Gases and liquids discharged into the environment had low levels of radioactivity and were within permissible guide values. It means in terms of the public protection that the maximum values of calculated individual effective dose reach the order of a tenth of microsievert. It is an insignificant fraction of the basic annual limit for personal exposure to radiation from the nuclear power plant operation. The limit set by the Public Health Authority of the Slovak Republic has determined to be 50 microsieverts per year.2015 Operation and Safety Report of Mochovce and Bohunice V2 NPPs

Assessment of the occupational health and safety and the evolution of the occupational injury rate at Slovenské elektrárne is carried out in accordance with the requirements of Act No 124/2006 on occupational health and safety, as amended, STN OHSAS 18001:2009 and the Company’s internal regulations. One registered occupational accident was recorded among the employees of SE in 2015. One fatal occupational accident was recorded among the employees of our contractors in 2015.
severe accidents according to rating of ENEL (more than 30 sick leave days)
Calendar days of absence due to occupational accidents of SE employees decreased by 77% in 2015 versus 2011.

**Severity Index, SI: The number of lost work days of due to work-related accidents which occurred and were recorded, except for the accidents sustained on the way from/to work per onethousand of worked hours; SI = (number of lost days/worked hours) x 103
In 2015 inspection activity in the area of occupational health and safety was carried out in accordance with the approved plans for inspection activities and internal requirements. Totally 5 074 inspections were carried out and 3 811 shortcomings were detected in Slovenské elektrárne employees, in case of contractors 8 519 inspections were carried out and 11 646 shortcomings were detected. In 2015 the state supervision authority carried out totally 22 inspections in Slovenské elektrárne workplaces, resulting in detection of 61 shortcomings.
trainings of employees (defensive driving course for drivers of company cars, safe driving course on the training ground, trainings of foremen, training and drills of fire-fighters in activities after fall of an aircraft),
analysis of regime measures ensuring protection of employees at remote workplaces and ones working alone in workplace,
continuation in replacement of uncertified tools,
establishing of new first-aid spots in operational areas of NPP (including resuscitation devices),
analysis of machine tools in plants from the aspect of the protection against rotating components,
ensuring strengthened inspections during general overhaul in Nováky thermal power plant and outage in Mochovce NPP by specialists from safety units from other Slovenské elektrárne plants.
In 2015 we invested in total 4 369 798 euro for the purposes of safety enhancement (e.g. re-insulation of connecting lines and earthing line in Mochovce NPP 400 kV and 110 kV substations, reconstruction of Nováky 110 kV substation, asbestos removal in Mochovce NPP).
Assessment of the fire protection at SE is carried out in accordance with the requirements of Act No 314/2001 on fire protection, as amended, STN OHSAS 18001:2009 and the Company’s internal regulations. In 2015 no fire occurred in plants and buildings of Slovenské elektrárne.
The internal inspection activities of the specialised units in the field of fire prevention were performed by fire prevention technicians at individual plants and at the headquarters in accordance with the approved inspection plans for 2015. In total 901 preventive fire protection inspections were carried out during which 630 shortcomings were detected. During 2015 the state fire inspection authority carried out four complete fire prevention inspections. Eleven shortcomings were detected and removed in accordance with the defined deadlines. Additional inspections carried out in Slovenské elektrárne plants included two specific fire protection inspections and two fire protection inspections related to the correction of shortcomings identified by previous fire protection inspections.
Slovenské elektrárne pays close attention to the issue of security, which is divided into the areas of information security, physical protection of assets, crisis management, and operational continuity management.
Top management is supported in these areas by the Security Committee of SE and the Crisis Management Team of Slovenské elektrárne.
All activities are carried out in a manner to ensure an adequate level of protection for the Company's protected assets against identified security risks and the conformity of operations with the security interests and objectives of the Slovak Republic.
The Internal Audit helps the organisation to accomplish its objectives by bringing a systematic, disciplined approach to evaluate and improve the effectiveness of the risk management, control, and governance processes.
Based on identified risks and suggestions from the management, the Internal Audit Department draws up the annual plan of audits taking into account results of the risk analysis performed on an annual basis. A final report as an outcome from internal audits, includes the list of remedial measures. They are submitted to the Company management on a monthly basis pursuant to agreed deadlines. During 2015 the Internal Audit Department carried out ten planned internal audits.
Slovenské elektrárne operates an Ethics Hotline; it was used and submitted four suggestions and complaints concerning breaches of ethical principles to the Internal Audit Department.
