Georgia Power announced what the company identified as "several key milestones" at the Vogtle nuclear expansion near Waynesboro, Georgia, including the placement of the middle containment vessel
ring for Unit 4.
Japanese developers say they plan to send the probe into the primary containment vessel
of Unit 3 at Fukushima in July to study the extent of damage and locate parts of melted fuel thought to have fallen to the bottom of the chamber, submerged by highly radioactive water.
(TEPCO), the operator of the Fukushima Daiichi plant, failed to get a comprehensive report in its attempt to find nuclear debris in a containment vessel
with the help of the (http://www.world-nuclear-news.org/RS-Survey-under-way-of-unit-1-vessel-2003174.html) PMORPH survey robot 6 developed by Hitachi-GE Nuclear Energy and the International Research Institute for Nuclear Decommissioning (IRID) 6 on Thursday.
The 1.9 million-pound lower ring was lifted into place by the heavy lift derrick, one of the largest cranes in the world, and is the first of three containment vessel
rings for Unit 4.
Toshiba Corp., co-developer of the "scorpion" crawler that was demonstrated Tuesday, said the robot will venture into the Unit 2 reactor's primary containment vessel
in August after a month of training for its handlers.
Through a thorough survey of the plant, TEPCO found the radiation levels of the Number 1 reactor as of late ranged between 7.0 and 9.7 sieverts (enough to poison a healthy human being) per hour after surveying six locations within the primary containment vessel
, reports the Japan Times.
(IFII used to be known as Ishikawajima-Harima Fleavy Industries Co., Ltd.; the name was condensed in 2007.) IHI is already using one Kurion machine, called the Fukushima Inspection Manipulator, to help pinpoint leaks in the pressure containment vessel
surrounding Unit 2's reactor.
In addition, Graham's equipment can be found in diverse applications, such as metal refining, pulp and paper processing, shipbuilding, water heating, refrigeration, desalination, food processing, pharmaceutical, heating, ventilating and air conditioning, and in nuclear power installations, both inside the reactor vessel and outside the containment vessel
The NEI has claimed that a typical plant features layers of protection with fencing and heavy patrolling right from the boundaries to the vital equipment and the containment vessel
as well has multiple layers of steel and concrete.
from camera footage that vapor was rising from the central area of the fifth floor of the building -- just above the reactor's primary containment vessel
-- and it had not stopped as of 12:30 p.m., the plant operator said.
After disassembling and removing the existing closure heads, the new RVH and CRDMs were assembled at the nuclear reactor containment vessel
