Approaches to Accounting and Prediction of Fast Neutron Fluence on VVER Pressure Vessels for Estimation of RPV Residual Lifetime in Compliance with Russian Utility's Procedure

Autor: Nikolay Khrennikov, Gennady Borodkin, Pavel Borodkin, Yuriy Ryabinin, Valeriy Adeev

Publikováno v: EPJ Web of Conferences, Vol 106, p 02014 (2016)

The Paper describes a new Russian Utility's regulatory document (RD EO) which has been recently developed and implemented since the beginning of 2013. This RD EO includes the procedure of RPV FNF monitoring and provides recommendations on how to pred

Application of Integral Ex-Core and Differential In-Core Neutron Measurements for Adjustment of Fuel Burn-Up Distributions in VVER-1000

Autor: Pavel Borodkin, Nikolay Khrennikov, Gennady Borodkin

Publikováno v: IEEE Transactions on Nuclear Science. 57:2670-2675

The paper deals with calculational and semi-analytical evaluations of VVER-1000 reactor core neutron source distributions and their influence on measurements and calculations of the integral through-vessel neutron leakage. Time-integrated neutron sou

Methodology of Fuel Burn Up Fitting in VVER-1000 Reactor Core by Using New Ex-Vessel Neutron Dosimetry and In-Core Measurements and its Application for Routine Reactor Pressure Vessel Fluence Calculations

Autor: Pavel Borodkin, Nikolay Khrennikov, Gennady Borodkin

Publikováno v: EPJ Web of Conferences, Vol 106, p 02008 (2016)

Paper describes the new approach of fitting axial fuel burn-up patterns in peripheral fuel assemblies of VVER-1000 type reactors, on the base of ex-core neutron leakage measurements, neutron-physical calculations and in-core SPND measured data. The d

13th International Symposium on reactor Dosimetry, 25.-31.05.2008, Alkmaar, Netherlands

The support structure of a reactor pressure vessel experiences a high mechanical stress during reactor operations. In addition, supposed accident conditions and ferritic steel properties result in a low limiting value for the ductile-to-brittle trans
