Power unit No.4 of Tianwan NPP being constructed in China under the Russian VVER-1000 design is getting prepared to the nuclear fuel loading - at the beginning of May a necessary stage in the program of the power unit preparation to the first criticality - hot run of the reactor plant was successfully completed. Therefore, the safe and efficient operability of the unit equipment and process systems was proved.
“We have entered the final straight in terms of the power unit preparation to the first criticality. Now, we’ll have to revise the main and auxiliary equipment of the power unit primary and secondary circuit, obtain permit of the Regulatory Authority for fuel loading”, - said Aleksey Bannik, the director for NPP projects in China of JSC ASE EC. The power start-up is scheduled for September 2018.
“In the period of the reactor plant hot tests - a technological process, the most important one at the stage of commissioning works - at the temperature of 260 degrees Celsius a whole complex of pre-startup tests was fulfilled: primary and secondary circuit overpressure protection systems, main circulation pumps on hot parameters of the reactor plant, auxiliary power supply systems were tested and checked”, - mentioned Valery Kedrov, deputy director of JSC ATOMPROEKT Design Institute for Tianwan NPP.
For reference:
Tianwan NPP is the largest facility of the Russian-Chinese economic cooperation. Start-up of power units No.1 and No.2 was held in 2007. These first two units of Tianwan NPP annually generate above 15 billion KW/hour of electric power.
The cooperation in construction of the second stage - Units No.3 and No.4 of Tianwan NPP is carried out based on the Protocol signed between the Government of the Russian Federation and the Government of the People's Republic of China. Tianwan NPP design is based on the Russian project AES-91 with reactor type VVER-1000, which fully meets the requirements of up-to-date regulatory and technical documents of China, Russian Federation and IAEA. Construction of Tianwan nuclear power plant is being carried out by Jiangsu Nuclear Power Corporation (JNPC) in cooperation with Russian company Atomstroyexport included in ASE Group of Companies.
For reference:
ASE group of companies was established in the frame of the engineering division of Rosatom State Corporation by merging leading companies of the industry: JSC ASE EC - Atomstroyexport JSC - Atomenergoproekt JSC - ATOMPROEKT JSC
ASE is one of the global leaders in nuclear power engineering and accounts for 31% of the global NPP construction market. Representative offices, branches and front offices are operating in 15 countries. Over 80% of the portfolio are accounted for by foreign projects.
It implements high power NPP design and construction projects, RAW and SNF management facilities, thermal power facilities and renders services within the full range of EPC, EPC(M) and PMC for any complex engineering facilities.
ASE company develops and implements an innovative Multi-D project management system in the area of complex engineering facilities construction which allows more efficient management of budgeting, deadlines and quality.
The President of ASE group is Valery Limarenko, Doctor of Economics.
