BİR ISI BORULU NÜKLEER REAKTÖRDE ISI LİMİTASYONLARININ ANALİZİ

Dünyada nükleer reaktörlerde kazaların meydana gelmesinden sonra, daha güvenli ısı çekimini sağlayan sistemler kullanılmaya başlanmıştır. Bunlardan biri de pasif güvenlik sistemi olan ısı borulu nükleer reaktördür. Isı boruları kullanılırken en önemli konulardan biri ısı limitasyonlarının belirlenmesidir. Bu makalede 900 K’de çalışan ısı borulu reaktörde ısı limitasyonları hesaplanmıştır. Isı borusunun çalışma sıvıları olarak potasyum, sodyum ve lityum ayrı ayrı ele alınmıştır. Isı borusu limitasyonlarının hesaplamalarında en uygun korelasyonlar kullanılmıştır. Üç farklı çalışma sıvısının ısı limitasyonları birbirleriyle kıyaslanmıştır. 900 K için potasyum, sodyum, ve lityum çalışma sıvılı ısı boruları için en yüksek ısı çekimleri sırasıyla 35,110 ve 24 kW olarak bulunmuştur. Isı limitasyonları kıyaslandığında 900 K için en yüksek ısı çekilimi sodyum soğutuculu ısı borusu olarak saptanmıştır.
