図2は、本実施形態に係る中性子モデレータの斜視図である。図3は、図2の側面図である。図4は、図3の上面図である。図5は、図3に示すA−A断面の断面図である。中性子モデレータ1は、図3に示すように、図1に示すターゲット127側を上面1A、照射部128側を下面1B、外周1Pを有する略円柱体である。図3に示すように、中性子モデレータ1の厚みを図1に示すターゲット127から照射部128に向かう中性子の通過方向の厚みLとした場合、中性子モデレータ1は、直径Dに対する厚みLの比(厚みL/直径D)が180%以上であることが多い。
以下、第1中間積層体を製造する工程について、図6から図10及び適宜図2から図5を用いて説明する。図7は、第1焼結体を製造するパルス通電加圧焼結装置を模式的に示す模式図である。図8は、本実施形態に係る第1焼結体の側面図である。図9は、図8の上面図である。図10は、本実施形態に係る第1焼結体の積層体である第1中間積層の積層状態を説明するための説明図である。図11は、本実施形態に係る第1中間積層体を製造する機械加工工程を説明するための説明図である。図12は、本実施形態に係る第1中間積層体を示す模式図である。
以下、第2中間積層体を製造する工程について、図6、図13から図17及び適宜図2から図5を用いて説明する。図13は、第2焼結体又は第3焼結体を製造するパルス通電加圧焼結装置を模式的に示す模式図である。図14は、円盤状のフッ化マグネシウム焼結体を模式的に示す模式図である。図15は、図14の上面図である。図16は、本実施形態に係る第2焼結体の積層体である第2中間積層体の積層状態を説明するための説明図である。図17は、本実施形態に係る第2中間積層体を示す模式図である。
以下、第3中間積層体を製造する工程について、図6、図13から図15、図18から図20及び適宜図2から図5を用いて説明する。図18は、本実施形態に係る第3焼結体の積層体である第3中間積層体の積層状態を説明するための説明図である。図19は、本実施形態に係る第3中間積層体を製造する機械加工工程を説明するための説明図である。図20は、本実施形態に係る第3中間積層体を示す模式図である。
中性子モデレータの組み立て工程S40において、第2中間積層体21の上面21Aと第1中間積層体11の下面11Bとを接合する。第1中間積層体11の上面11Aが中性子モデレータ1の上面1Aになる。また、第2中間積層体21の下面21Bと第3中間積層体31の上面31Aとを接合する。第3中間積層体31の下面31Bが中性子モデレータ1の下面1Bになる。第2中間積層体21、第1中間積層体11及び第3中間積層体31は、積層されることにより、図2から図5に示す中性子モデレータ1となる。
図21は、本実施形態の変形例に係る第1焼結体の第1リングの側面図である。図22は、本実施形態の変形例に係る第1焼結体の第2リングの側面図である。図23は、本実施形態の変形例に係る第1焼結体の第3リングの側面図である。本実施形態の変形例として、図7の焼結型の平面視で中央の位置に配置する中子を円筒形状から円錐台形状に変更している。
図25は、第3焼結体の変形例を製造するパルス通電加圧焼結装置を模式的に示す模式図である。第3焼結体ds3は、円盤状のフッ化マグネシウム焼結体であり、フッ化マグネシウム焼結体の外周面がテーパである。上述したように、この円盤状のフッ化マグネシウム焼結体の外周形状には、中心軸に沿って直径が徐々に異なるテーパ面1Tを有している。そして、第3焼結体の変形例において、テーパ面1Tが焼結型の枠型GDで成形されている。枠型GDは、焼結型の外周に位置するリング状の枠型であって、内径に角度βのテーパ面GRTを有している。これにより焼結後の第3焼結体ds3の外周面がテーパとなり、割れ又は欠けが抑制される。そして、中性子モデレータ1は、焼結後の第3焼結体ds3の外周面がテーパであって、かつ貫通孔H1のない円盤状の第3焼結体ds3を少なくとも1つ含む。テーパ面を有する枠型GDを用いることで、直接図18に示すような、外周面にテーパ面を有する第3焼結体ds3を得ることができるので、製造工程を低減できる。
試料は、純度99%以上のフッ化マグネシウム粉末(森田化学工業製)を、内容積が直径φ(mm)×厚さ(mm)となる焼結型に充填し、タッピング充填を行った。この焼結型の中央には、円筒形の中子を配置した。
