The objective of the conference was to analyze the current status of activities aimed at ensuring NPP I&C safety, identify the areas of further activities, and exchange experience. The importance of this subject area is determined by the following factors: I&Cs represent NPP systems that are changed most intensively because new information technologies and electronic components are emerging on the market and computer equipment is used extensively, causing obsolescence of NPP I&Cs. The use of new hardware components and improvement of hardware features increase I&C reliability and allow solving fundamentally new tasks, meanwhile they complicate safety assessment and require development of new methodologies for this assessment; Lessons learnt from the Fukushima accident have changed the requirements for NPP I&Cs (in particular, for seismic resistance) and necessitated the development of new systems and automation hardware (particularly, sensors for accident and post-accident monitoring systems);

3 Requirements for NPP I&C established in international documents of IAEA and International Electrical and Technical Commission have been changed last years and are under modification at present as well. The conference was opened by G. Gromov, SSTC NRS Director. The opening speech was given by: O. Mykolaichuk, Chairperson of the State Nuclear Regulatory Inspectorate of Ukraine; J. Eiler, Academic Secretary of IAEA working team Nuclear Power Plant Instrumentation and Control ; H. Hashemian, Representative of US Nuclear Society, President of Analysis and Measurement Services Corporation (AMS); T. Tkach, Head of Department in NAEK Energoatom ; M.

4 In addition to the plenary sessions, the following sections were arranged at the conference: 1. New NPP I&Cs (Chairs Yu. Rozen, V. Sklyar). 2. Scientific and methodological problems related to NPP I&C safety (Chairs S. Artiukh, V. Severin). 3. Training course related to on-line monitoring of NPP measurement devices and control systems (joint measure arranged by US Company, AMS, and PLC Manometr- Kharkov ). The conference participants pointed out the following: 1. Significance of international cooperation for NPP I&C safety, since the issues considered are beyond the national frameworks, they are international. 2. Successful cooperation of Ukraine and IAEA related to arrangement of workshops, conferences, participation in IAEA publications, mission of IAEA experts in Ukraine etc. 3. The need for harmonizing the national regulatory documents with the requirements of the international standards related to both requirements for NPP I&Cs and methodologies for testing of I&C compliance with these requirements. 4. Achievement of the international level of performance for new I&Cs developed by Ukrainian enterprises, and implementation of these I&Cs in the Russian Federation, Armenia, Bulgaria, Czech Republic, India, the Republic of South Africa, and other countries. 5. The 5 th International Scientific and Technical Conference NPP Instrumentation and Control Systems: Safety Aspects was successfully completed, its goals were achieved. DECISIONS: 1. Recommend the following areas of further activities related to NPP I&C safety: Develop regulatory requirements for NPP I&C cybersecurity, methodologies to assess and provide cybersecurity; Modernize NPP I&Cs to extend power unit operation lifetime; Develop and implement methodologies for on-line monitoring of NPP I&C instrumentation channels and their components; Develop remote control sensors for NPPs;

5 Develop scientific and research activities to assess impact of new informational technologies on I&C safety; Develop sensors for accident and post-accident monitoring systems; Ensure operational feedback related to analysis of operational events caused by I&Cs (digital events); Manage knowledge related to NPP I&Cs, qualification of NPP I&Cs; Develop activities for NPP I&C functional safety including quantitative characteristics of functional safety; Develop activities for man-machine interface (procedure computerization systems, new developments in designing of control points, computerized systems for decision making and operator support). 2.
