October, 2008
  On 23-24th October, 2008 the regular conference of Coordination Council of Experts was held in CJSC “SRPA”Impuls” of ACS TP NPP NNEGC “Energoatom”.
  During the conference the reports about ACS TP reconstruction for the 3rd quarter, 2008 of NPP representatives were heard. Also there were considered the possibility of ACS TP updating till 2010.
  At the presentation of products a particular interest of members of CCE was caused by the new developments of CJSC “SRPA”Impuls” such as: CRCS-1000, SHC NOS RH, LVCD RTZO.

  There was presented the following production of CJSC “SRPA”Impuls”:

• low-voltage complete devices RTZO;
• fragment of SHC of reactor room normal operation system;
• fragment of SHC of control rod control system.

• primary coolant leak monitoring system (subsystem of acoustic control and humidity control);
• free and loose part detection system.

July, 2008
  Acceptance tests of the low-voltage complete devices RTZO intended for power supply and control of electric motor of shut-off and control valves were successfully carried out.
  Low-voltage complete devices RTZO are elements of NPP safety operating system. They could be used for RTZO-69 assemblies replacement.
  Acceptance tests of digital software & hardware complex of normal operation system of reactor hall (SHC NOS RH) were successfully carried out for Zaporozhye NPP power unit 5.
  SHC NOS RH intended for use as a part of reactor hall normal operating system of NPP power units for supplying of technological protection functions, interlocks, alarm system, regulation and remote control of drives.
  SHC NOS RH has such distinctive features as:

• reliability growth by means of using redundant structures, possibility of maintenance service of SHC in all channels with retention ability of all functions to work;
• reduction of equipment quantity by using digital means of processing and data communication in comparison with existing NOCS on the basis of unified hardware;
• reduction of equipment quantity that realize the functioning of CIS lower level of power unit by means of realization of primary processing signals in SHC and their transferring to upper level of CIS;
• reduction of cable communications quantity by using digital optical interface and it is steady against electromagnetic interference;
• presence of current and retrospective information presentation about technological parameters state, protections, interlocks, ACS, drives;
• diagnostic of hardware states, communication links, input signals, primary and secondary electrical feed circuit;
• scalability, possibility of realization in several stages.

June,2008
   Acceptance tests of software & hardware complex of control rod control system RCS-Impuls for Zaporozhye NPP, power unit 2 were successfully carried out.
  New system was estimated very high by NNEGC “Energoatom” experts, Ukrainian and Russian NPPs, State Nuclear Regulator Committee of Ukraine, Certification Centre of ACS, design organization.

  SHC RCS-I has the following distinctive features:

• full redundancy of power supply of magnets with automatic bumpless transfering and the possibility of replacing during its running;
• realization variety of emergency and preliminary protection systems (2 three-channel complete sets, one of which is realized on “hardwired” relay logic);
• structure of SHC includes complete sets of power supply equipments (both logic and electromagnets);
• echelon facility of built-in diagnostic archive with displaying and archiving on the control and diagnostic server.

  This kind of work was carried out on the base of development experience, implementation and operation of similar systems for WWER-440 power units of the Rovno NPP.

   Testing of a new neutron flux monitoring system was successfully passed at ZNPP produced by Severodonetsk RPA “Impuls”.
   At Zaporozhye NPP power unit 2 successfully took place tests of new digital facilities of neutron flux monitoring and measurements (NFMS-I). From these test results depended if we were permitted further power unit operation of Ukrainian NPPs by State Nuclear Regulator Committee of Ukraine.
   Before scheduled repair of power unit 2 in accordance with permitted application and carrying out a number of working operations on May 31, at 12:01 there was a signal of imitation of switching-off turbo-feed pump (TFP-1) and in accordance with algorithm the accelerated preliminary protection activated with automatic unloading unit up to 450 MW. Work of systems and mechanisms occurred in planned mode. There were no abnormalities and disturbances. A new algorithm of reactor neutron flux monitoring system was approved with the participation of chief state inspector of nuclear and radiation safety of Ukraine Mikhail Gashev, the first vice president of technical director of NNEGC “Energoatom” Ivan Foltov, general director SS ZNPP
   Vyacheslav Tishchenko, chief engineer of SS ZNPP Alexander Shavlakov and other experts. NFMS-I was produced by Severodonetsk RPA “Impuls”. Its system is intended to replace previously installed on neutron flux monitoring system units NFMS.
   The success of carrying out this work confirmed the right acceptance of design solutions and dynamic stability of the domestic NPPs.
   The next step made by nuclear powers, designers and developers is implementation of a new system to improve the safety of nuclear power plant and prolongation of their resources.
