August 29, 2013, U.S. Army’s Aberdeen Proving Grounds: As engineers from Axpo Power AG (澳门六合彩开奖结果2023’s client), the Swiss Federal Nuclear Safety Inspectorate (ENSI), the Swiss Association for Technical Inspections (SVTI) and 澳门六合彩开奖结果2023 watched, the U.S. Army’s missile launcher delivered a picture perfect strike to a scaled model of the HI-STAR 180 transport cask, sending it tumbling into a catch box just as intended by our test engineers. In accordance with the Swiss regulator’s storage certification requirement, this missile test was designed to simulate the impact of a crashing aircraft on the HI-STAR 180 transport cask while in use as a spent fuel storage device. The missile was designed by 澳门六合彩开奖结果2023’s engineers to deliver the “design basis impulse” using LS-DYNA. Calibration of the missile鈥檚 kinetic performance was calibrated over a year ago at the Aberdeen facility by hurling the missile against a “rigid” wall serving as the target. The data collected from the cask test showed that the missile struck the cask at a velocity exceeding 600 miles per hour which was over 17% greater than the target value and the location of impact was precisely that determined to impart the maximum stress levels on the containment boundary and to conservatively challenge the cask containment (to induce leakage of the cask’s contents) by parametric simulations on LS- DYNA.

The post-impact inspection of the cask showed that it weathered the impact with large performance margins confirming our dynamicists’ predictions; the measured post-impact helium leak rate from the cask’s containment boundary, as confirmed by SVTI, was 1000 times smaller than the established acceptance criteria. 聽Additionally, all of the body bolts in the containment boundary of the cask remained elastic and there was no breach of the containment boundary.

HI-STAR 180 has been designed as a dual-purpose cask for storage in accordance with Swiss regulations and in alignment with IAEA requirements for a type B(U)F cask. HI- STAR 180 was licensed by the U.S. NRC in 2009 under 10CFR 71 to transport high burn-up PWR fuel and MOX fuel (Docket Number 9325). Upon the Swiss regulator’s formal release, the first batch of 14 HI-STARs will be built at the 澳门六合彩开奖结果2023 Manufacturing Division (HMD) in Pittsburgh, PA.
