Abstract (2. Language): 
The potential of a catalyzed (D, D) fusion-driven hybrid blanket is investigated for the regeneration of light water reactor spent fuel. Total enrichment grade is 2.172 % at beginning of regeneration. The hybrid blanket has excellent neutronic performance and is investigated to achieve different cumulative fission fuel enrichment (CFFE) grades. A regeneration period of up to 36 months is investigated by a plant factor of 75% under a first wall catalyzed (D, D) fusion neutron current load of 1014. Neutron (14.1 MeV)/cm2. s and 1014 neuton (2.45 MeV)/cm2. s. This corresponds to a first wall load of 2.64 MW/m2. Regeneration periods of 12, 20, 28 and 36 months are considered, resulting in final enrichment grades of 3.0, 3.5, 4.0, and 4.5 %, respectively. The blanket energy multiplication M is quite high and increases only by ~ 30 % in 36 months. The electricity production remains fairly constant during this period. Consequently, this power exploits the non-nuclear island very well. At the same time, the peak-to-average fission power density ratio r decreases by ~10 %.

Abstract (Original Language): 
Hafif su reaktörü kullanılmış yakıtı yenilemesi için katalize (D, D) füzyon sürücülü bir hibrid reaktörünün potansiyeli incelendi. Yenilemenin başlangıcında toplam zenginleştirme yüzdesi % 2.172 olarak ele alındı. Ele alınan hibrid blanket mükemmel nötronik perfonmans gösterdi ve değişik kümülatif fisyon yakıtı zenginleştirme oranları elde etmek için araştırma yapıldı. 1014 nötron (14.1 MeV)/cm2 s ve 1014 nötron (2.45 MeV)/cm2 s.'lik bir cidar katalize (D, D) füzyon nötron akı yüküne maruz blanket, 36 aya kadarlık yakıt yenileme peryodu % 75'lik bir tesis faktörü ile araştırıldı. Bu 2.64 MW/m2'lik bir cidar yüküne tekabül etmektedir. 12, 20, 28 ve 36 ay yenileme periyotları için sırayla 3.0, 3.5, 4.0 ve % 4.5 zenginleştirme yüzdeleri elde edildi. M blanket enerji çoğalım katsayısı oldukça yüksek olup ve 36 ayda sadece % 30 oranında artmıştır. Dolayısıyla elektrik üretimi bu periyot süresince oldukça sabit kalır. Aynı zamanda r maksimum güç yoğunluğun ortalamasına oranı yaklaşık % 10 mertebesinde azalmaktadır.
