India, under its breeding blanket R&D program for DEMO, is focusing on the development of two tritium breeding blanket concepts; namely the lead-lithium-cooled ceramic breeder and the helium-cooled ceramic breeder (HCCB). The study presented in this paper focuses on the neutronic design analysis and optimization from the tritium breeding perspective of the HCCB blanket. The Indian concept has an edge-on configuration and is one of the variants of the helium-cooled solid breeder blanket concepts proposed by several partner countries in ITER. The Indian HCCB blanket having lithium titanate (Li 2 TiO 3 ) as the tritium breeder and beryllium (Be) as the neutron multiplier with reduced-activation ferritic/martensitic steel structure aims at utilizing the low-energy neutrons at the rear part of the blanket. The aim of the optimization study is to minimize the radial blanket thickness while ensuring tritium self-sufficiency and provide data for further neutronic d...

基于一维中子学模型的印度DEMO HCCB毯子初步性能分析和优化

印度在其DEMO繁殖毯研发计划下，致力于两个two繁殖毯概念的开发。即铅锂冷却的陶瓷育种机和氦冷却的陶瓷育种机（HCCB）。本文介绍的研究从HCCB毯子的tri繁殖角度着重于中子设计分析和优化。印度的概念具有优势，是ITER的几个伙伴国家提出的氦冷却固体育种毯概念的变体之一。印度HCCB毯以钛酸锂（Li 2 TiO 3）作为breed繁殖剂，而铍（Be）作为具有减活化铁素体/马氏体钢结构的中子倍增器，其目的是利用毯子后部的低能中子。
