Necessity of demonstration test to evaluate the structural integrity of a basket for accident conditions arose during license approval procedure for the WSPP's dry storage facility named MACSTOR/KN-400. A drop test facility for demonstration was constructed in KAERI site and demonstration tests for basket drop were conducted. As the upper welding region of a loaded basket was collided with a dropped basket during the drop test, the welding in this region was fractured and leakage happened after the drop test. The enhancement of basket design was needed since the existing basket design was not able to satisfy the performance requirement. The directions for design modification were determined and six enhanced designs were derived based on these directions. Structural analyses and specimen tests for each enhanced design were conducted. By evaluating structural analysis results and test results, one among six enhanced designs was decided as a final design for revision. The final design was the one to reduce the height of central post of a basket and to decrease the impact velocity with a dropped basket. Test basket models were fabricated with accordance with the final enhanced design. Additional demonstration test was performed for this test model and all the performance requirements were satisfied.

최근 국제원유가격이 급변하고 있는 가운데 그 결제종화인 달러화가치의 급격한변동으로 인한 유가왜곡 현상이 심화되어 왔으며, 이에 따라 최근 OPEC중 일부국가에서 이의 시정을 위한 유가바스켓제도의 도입움직임이 활발히 전개되고 있다. 이글은 국제석유전문가인 Ramaswamy씨가 이제도에 대해 Asian Wall Street Journal씨에 기고한 글을 옮긴 것이다. <편집자 주>
