Calculation of the Probability of Coolant Flow Arising in the Collector of VVER Steam Generator Using the MAVR-4.1 Computer Program

Autor: P. V. Alekseev, A. A. Tutnov, O. D. Loskutov

Publikováno v: Atomic Energy. 114:21-27

The regulatory documentation establishes the maximum admissible fracture probability for the collector vessels of steam generators at 10–7 yr–1 per unit, which cannot be compensated by regular accident localization systems. In this connection, it

Evaluation of the effect of perforations in the collector vessel of a steam generator on the critical stress intensity coefficient

Autor: A. A. Tutnov, O. D. Loskutov

Publikováno v: Atomic Energy. 110:26-32

An approach to calculating the effective critical stress intensity coefficient for mainline cracks in the perforation zone of the first-loop collector of a VVER steam generator is examined. The energy criterion is chosen as the condition for crack st

Evaluation of the probability of a leak in the flange joint of a steam-generator collector cover as a result of stud failure

Autor: O. D. Loskutov, A. A. Tutnov

Publikováno v: Atomic Energy. 102:426-429

A two-stage approach to evaluating the probability of leak appearing in the flange joint as a result of a failure of the securing studs is described. First the probability of only one stud failing is calculated. This probability depends on, specifica

Computational investigation of the effect of hydraulic and nondestructive test parameters on the strength reliability of the heat exchanger tubes of a steam generator

Autor: A. F. Getman, O. D. Loskutov, A. A. Tutnov

Publikováno v: Atomic Energy. 102:264-270

The results of calculations of the probability of a leak appearing in the tube band of steam generator in a VVER-440 reactor system during operation are presented. The MAVR-1.1 computer code is used to calculate the probability of the formation of a
