Recently, the Tokyo Electric Power Company (TEPCO) dispatched a robot with a smart phone to the No. 3 reactor of the Fukushima Daiichi nuclear power plant, which was destroyed during the 2011 Fukushima nuclear disaster. The outside of the robot is wrapped in a 3D printed casing, and the Tokyo Electric Power Company system can use it to obtain images and data inside the reactor, so that it is hoped to understand the state of the main vessel (PCV) hatch of Unit 3. These places cannot be surveyed by manpower due to strong nuclear radiation.
In March 2011, a magnitude 9 earthquake occurred in the eastern seas of Japan, causing a tsunami, which led to a serious nuclear accident at the Fukushima Daiichi nuclear power plant under the Tokyo Electric Power Company. The accident was considered to have been since 1986 in Cherkbelli, Ukraine. The most serious nuclear disaster since the nuclear leak. Now that four years have passed, the consequences of this disaster have not been eliminated, and the clean-up work for the Fukushima nuclear power plant is still far away.
At present, Tokyo Electric Power Company is investigating the status of the main vessel (PCV) hatch of Unit 3 to determine the extent of its damage, and is developing procedures and methods to remove nuclear fuel debris.
In fact, on September 9 this year, the company has already sent a portable camera to the hatch. Now the company has sent a remote control robot with a larger range of activities, and connected a smart phone to collect more More data and images. The device's housing is created with a 3D printer and is equipped with an LED light that allows the device to transmit information to the remote computer in an infinite way. In order to make it easy to take pictures, this smartphone can be flipped back and forth 180 degrees. In addition, the shape of this robot is also very similar to a tank, it can cross obstacles of 5 cm high.
Tokyo Electric Power Company announced that their robots have received valuable information so that they can see that there are no stains on the upper periphery of the hatch cover, but sewage, dirt and rust are found inside. In the first survey conducted in September, the company also found that the hatchment did not leak cooling water from the inside, and it was not damaged. However, the floor is wet and they cannot confirm where the water comes from. In addition, the video shows white noise caused by extremely high levels of radiation.
However, it is still too early to conclude the current status of the Unit 3 reactor and even the entire Fukushima Daiichi nuclear power plant. This is only the first time that the company uses remotely controlled 3D printing robots to collect information from the Fukushima nuclear power plant. Steps, and this approach may be further refined and expanded to help staff understand the current internal situation of the nuclear power plant.
Below is a video of this 3D printing robot surveyed at the hatch of Unit 3:
A pet Strap Dog Harnessis is equipment consisting of straps of webbing that loop nearly around-that fasten together using side release buckles-the torso of an animal.
These strap dog harnesses generally are made to have both a strap on the chest in front of the forelimbs, and a strap around the torso behind the forelimbs, with straps in between connecting these two. Having a D-ring suitable for (pet tags and) a leash to clip to, they are most often used to restrain an animal, but dogs also particularly wear them to assist a person with a disability or haul people and items. There is also the lifting harness for dogs with disabilities, covered in this article.
Some come in different sizes, although many are size-adjustable with tri-glide slides to loosen or shorten the straps` length. The straps may come in a range of different colors, and some have reflective coating.
