| Contract Title | [Re-Notice] Technical Consulting on the CLP design method improvement and repair method for corroded CLP of NPPs |
| Contract Overview |
The purpose of this service is to investigate the optimized design calculation method for CLP of OPR1000 and APR1400 based on the S&L’s design experiences and to suggest optimized CLP repair method with examples of CLP repair performed for US or international operating nuclear units. ASME Section III, Division 2, Subsection CC, table CC-3720-1 shows the allowable strains of membrane and combined membrane and bending, and the calculated strains for the liner shall not exceed the values given in Table CC-3720-1. ASME CC does not provide specific requirements for liner strain calculation method, but the liner plate membrane strain can be estimated by summing the strains due to the effects of dead load, prestress, concrete creep and shrinkage, temperature, earthquake, etc. There is still uncertainty in the CLP strain calculations and it should be cleared and the calculation procedure should be improved through this consulting. In addition to this, the optimized CLP repair method should be suggested. |
| Estimated Value | USD 33,088 |
| Expected Completion Date | 2020-4-30 |
| Reason(s) for the Sole Sourcing | The purpose of this technical service is to review the CLP calculation of OPR1000 and APR1400 and to prepare the best approaches and procedures for the liner strain calculation of combined membrane and bending based on the S&L’s experiences since OPR1000 and APR1400 CLP calculations are based on S&L’s technology. This consulting service results will be used for evaluation on the corroded CLP of OPR1000 and APR1400 as well as new NPP’s CLP design. So, S&L’ is regarded as the sole company to perform the tasks of this contract. |
