| Contract Title | Consulting Services for Thermal Sleeve Wear Rate Evaluation for Hanul 1&2 RVH Penetration Nozzles |
| Contract Overview |
This consultation service covers below items related to calculation analysis for the thermal sleeve wear of reactor vessel head(RVH) penetration nozzle. - Computational Fluid Dynamic(CFD) analyses for the Reactor Vessel Head plenum region including Upper Internals, CRDM nozzles, and thermal sleeves. - Fluid Induced Vibration(FIV) Analysis using the results of CFD analyses - Structural analyses and wear analysis for the thermal sleeve in the CRDM nozzle - Establish wear criterion for the thermal sleeve |
| Estimated Value | JPY 20,000,000 |
| Expected Completion Date | 2020-09-30 |
| Reason(s) for the Sole Sourcing |
The contractor is considered as the only company to be able to provide above consultation services for the following reasons: - has many experiences on CFD and FIV analysis, and performed same analysis to establish wear criterion for the Japanese nuclear power plants. - familiar with RVH design in Hanul nuclear power plant 1&2 since the contractor designed similar 3-loop nuclear power plants in Japan. - results are expected to be delivered less than 5 months with limited design input data, so previous experiences for this analysis as well as having FEM models for similar NPP is mandatory for this project. |
