• 2018:26 Reaktorinneslutningarnas respons vid höga inre tryck och reducerad förspänning

  I föreliggande studie har det genom numerisk modellering undersökts huruvida tillämpning av alternativ B enligt Regulatory Guide 1.90 (R.G. 1.90) är ett tillförlitligt sätt att bedöma reaktorinneslutningens integritet. Vid genomförandet har två olika
