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: Borodkin Pavel, Borodkin Gennady, Khrennikov Nikolay

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

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

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

Uncertainties in the Fluence Determination in the Surveillance Samples of VVER-440

Autor: Konheiser Joerg, Grahn Alexander, Borodkin Pavel, Borodkin Gennady

Publikováno v: EPJ Web of Conferences, Vol 106, p 02006 (2016)

The reactor pressure vessel (RPV) represents one of the most important safety components in a nuclear power plant. Therefore, surveillance specimen (SS) programs for the RPV material exist to deliver a reliable assessment of RPV residual lifetime. Th
