[en] In order to calculate the seismic response of steel containment submerged in liquid, the fluid solid interaction (FSI) should be considered. This paper analyzes the seismic response of steel containment submerged in liquid based on the analytic method and the finite element method. The main works of this paper are given as follow: 1) The procedures of the seismic response of steel containment using analytic method are introduced; 2) On the basis of the finite element method, we propose the added mass method and the potential-based elements method respectively. At last, for choosing the proper method to solve the problem, the advantages and disadvantages between the analytic method and the finite element method are compared. (authors)

[en] Digital instrument and control system is main phase of development in nuclear power station. Comparing to analog system, digital I and C system has various advantages and can fulfill function by software which is limited to analog I and C system. This paper introduces profile of NPP I and C system, analyzing safety system and safety software, at last, attention must be paid to safety software verification and validation techniques so as to comply with NPP requirement.

[en] Nowadays, the computer equipment and information processing technology is coming into the engineering of instrument and process control. Owing to its convenient and other advantages, more and more utilities are more than happy to use it. After initial utilization in basic functional controlling, the computer equipment and information processing technology is widely used in safety critical control. Consequently, the people pay more attentions to the quality of computer software. How to assess and ensure its quality are the most concerned problems. The verification and validation technology of computer software are important steps to the quality assurance. (authors)

[en] In order to study the neutron moderation of D-T neutron generator, moderators with diffident materials and structures were predicted by Monte Carlo simulations. The neutron moderation structure is using hollow sphere as moderation and hollow cone as outlet. This can get the big and well-proportioned thermal neutron line. (authors)
