Abstract: The problems occurring in the fission product source term calculations for M310/CPR1000, EPR and AP1000 are briefly analyzed, based on the related regulations and standards, as well as operational feedback, review experiences and recent research achievements for nuclear power plants in China. The framework of fission product source term proper to China has been first studied and proposed in perspective of the purpose of source terms. The calculation processes of fission product source term are rearranged and the requirements for deferent reactor types are specified. The proposed framework can be taken as a foundation for solution of the long-standing problems in the calculation of fission product source term and provide reference for source term calculation.

Abstract: The integrity, objectivity and science of the evaluation index system will be directly related to the accuracy of the evaluation results. However, studies on the quantitative assessment of the effectiveness of the simulation model are not still perfect, comprehensive, and links between relevant literatures are not close enough. The main thing is the lack of systematic summary of the theoretical literatures. Therefore, this paper is summarized in three aspects, the research results, indices classification and their respective advantages and disadvantages, the applicable range of indicators.

Abstract: Changeable sensitivity and safety margin are proposed in this paper, which can avoid the voltage violation according to the operation of the current situation. A simulation test is presented to demonstrate the proposed method can decrease adjusting amounts and restoration time efficiently.

Abstract: This paper focuses on the application of cluster analysis algorithm in the indicators comparison of power industry. The provincial power companies are classified by the power supply quality indicator with K-means clustering algorithm to identify the standard companies and to verify the feasibility and effectiveness of the algorithm. The results show that the cluster analysis enable the power companies to accurately identify the gap between the enterprise and the benchmark of industry, so as to continuously improve the level of management and benefit.

Abstract: This paper analyzes the voltage quality problems on transmission line of 10kv distribution network, and then introduces a series compensation device, which is based on fast switching and can effectively solve the above problem. Furthermore, this paper calculates the voltage under a actual situation, which fits the expected results.

Abstract: Based on the Monte Carlo calculation method, geometric model of spent fuel storage pool Area I of small modular reactor is established, assuming infinite 6×6 type storage racks. Calculation results show that the reactivity is maximal when the water density is 1.0g/cm3. The value of k_eff is 0.8729 in normal storage condition. The spacing of storage racks in spent fuel pool would change in an earthquake accident condition. The values of reactivity of spent fuel pool in the assumed earthquake accident condition are also calculated. The values of k_eff are between 0.872 and 0.876. Both in normal condition and assumed earthquake accident condition, the values of k_eff are less than 0.95, to meet nuclear safety regulatory requirements.

Abstract: Data plays more and more important roles in the AEC field, especially in Nuclear power plant constructing and engineering. In this paper, except introduce the basic DP theory and methodology, we analyzed the key points while doing the DP in nuclear power plant. Based on the analyzed results, which is an actuality of Nuclear power engineering, the paper proposed the ways to improve the data integration solution to standardize the data of project data, reduce the redundant data in the database and improve the system integration efficiency.

Abstract: Tourist hotel is a “high energy consumption high emission high pollution” industry. So it is of great realistic significance of strengthening Chinese tourist hotel energy management under the background of low carbon economy. Aiming at the main problems of energy management of Chinese tourist hotel, we should begin from the following several aspects: First,To establish a scientific concept of hotel energy management and combine energy management training and assessment closely;The second is to build and improve energy management system and strengthen scientific and effective implement;The third is to establish a sound mechanism of hotel computer remote monitoring system to achieve hotel energy management information and automation.

Abstract: For the power load centers in china coast, large-scale development of new energy (such as offshore wind power and onshore wind power) is not only an effective means of control the bad weather (such as fog and haze), but also the practical requirements of coastal power shortage. In this paper, according to actual situation of China's large-scale wind power accessing to the coastal load centers centrally, also the characteristics of onshore and offshore wind farm models is considered, The voltage variation in the centralized model and detailed model is analyzed based on the platform of PSD-BPA, and the characteristic of each model is obtained. Research results have a certain reference value for China's coastal onshore and offshore wind power development.

Abstract: Setting up a practical power system containing wind farm small disturbance stability mathematical model, and the linearized equation of wind turbines and original equations of linear system, power system containing wind turbines augmented state formation matrix, turn the inverse iteration with PSASP software Rayleigh (Rayleigh quotient iterative algorithm and sparse matrix technique for large state matrix eigenvalues. In this paper, the Inner Mongolia power grid, wind power access to power system oscillation mode and the influence of the oscillation characteristics and meet the requirements of small disturbance stability of wind scale and operation control scheme. The influence of the wind farm is proposed for power system damping characteristics will not greater than the same capacity of synchronous generator's point of view.
