Ex-nuclear engineer’s proposal – diagrams

A former nuclear power plant designer with 36-year-experience Yuzo Uehara sent his proposal with the diagrams to this blog. Thank you, Mr. Uehara.

The Culvert Prefabrication Method System to cool down Fukushima Daiichi nuclear reactors while minimizing radiation exposure

Ex-nuclear engineer’s proposal – Mar26

A former nuclear power plant designer Yuzo Uehara raises some questions that are out of his field.

福島原発呼びかけ261720;着手されてると思うが日本の河川水理に携わっている方々、放射能汚染水は雨→山→地下水→川→ダム→川→海等と経路わかっ ています。カスケードに地下プールで順次希釈し放流はどれが最適解か解析できるはず。日本のため解答案を。原発設計OB#genpatsu

261720: I think those who are related to river hydraulics in Japan have been already working, but we already know that the path of the radiation contaminated water goes like this: rain > mountains underground water channels > rivers > dams > rivers > sea. After using underground pools with cascade to dilute, you can estimate where the best place to discharge is. Propose the solution for Japan!

福島原発呼びかけ261740;着手されてると思いますが気象の専門家各位、原発現地の周りに遮風壁設ければどれくらいの距離でどの位置で壁範囲・高さあ れば効果有無ご検討下さい。また雨・雪降れば当該地面の線量上がりますが広域拡散抑止になりますか。原発設計OB#genpatsu

261740: To all experts in meteorology. Please estimate where wind blocking walls should be installed around the site and how large and high they should be. And, when it rains or snows, radiation goes up at the site ground, but can the walls prevent radiation from spreading out?
