| * Type-B Maraging rods: design is ready. Will be ordered soon (Takahashi) * SUS rods: design is ready. Will be ordered with the PR assembly frame (Takahashi/Shoda) * Type-A Maraging rods * Installation procedure review concluded that the rods will not get tension above the static load during installation. * We employ the safety factor of 2 as requirement. * Takahashi will explain this and ask Obuchi-san to re-optimize the shape after the meeting. * Neck diameter can be increased to keep the safety margin * We want to keep the nail head diameter <= 8mm as much as possible. * Takahashi will ask Ojima whether 9mm nail head is possible or not just in case we need to increase the nail head size. |
* Order status: Type-B Maraging rods, SUS rods * Type-A Maraging rod re-optimization status (Takahashi) * Nail head diameter 9mm (possible ?) |
