FLEX, the nuclear plant 'Rescue Wagon' for natural and unnatural disasters

FLEX, the nuclear disaster “rescue wagon,” is the utility industry's latest method for meeting the Nuclear Regulatory Commission’s (NRC) new rules, which force 65 US plants to store extra emergency equipment onsite to handle big disasters. This nuclear industry plan emerged in response to the 2011 earthquake and tsunami in Japan that destroyed the Fukishima Dai-ichi nuclear plant.

Nuclear industry develops new emergency plan

ATLANTA — If disaster strikes a nuclear power plant in the U.S., the utility industry wants the ability to fly in heavy-duty equipment that could avert a meltdown.

That capability is part of a larger industry plan being developed to meet new rules that emerged since a 2011 tsunami struck the Fukushima Dai-ichi nuclear plant in Japan, flooding its emergency equipment and causing nuclear meltdowns that sent radiation leaking into the environment. The tsunami exceeded the worst-case scenario the plant was designed to withstand.

The effort, called FLEX, is the nuclear industry’s method for meeting new U.S. Nuclear Regulatory Commission rules that will force 65 plants in the U.S. to get extra emergency equipment on site and store it protectively. As a backup, the industry is developing regional hubs in Memphis, Tenn., and Phoenix that could truck or even fly in more equipment to stricken reactors. Industry leaders say the effort will add another layer of defense in case a Fukushima-style disaster destroys a nuclear plant’s multiple backup systems.

@ Sweden, Heyda,

Today's Water-Level according to Tepco:
- From 11:14 AM to 2:05 PM on December 10, Units 1-3 reactor water injection pump was switched from the regular reactor water injection pump on the hill to the reactor injection pump in the Turbine Building in order to prepare for newly building a shed for the regular reactor water injection pump on the hill which is scheduled from December 10 to 17. Since the target injection water amount at Unit 1 (total flow rate: 4.5m3/h) is the same as the lower limit flow rate of the reactor water injection pump in the Turbine Building (4.5m3/h) and the flow rate is difficult to adjust, Unit 1 reactor injection water amount was adjusted as follows to achieve the total reactor injection water amount of 5.0m3/h at 2:05 PM on the same day.


Feed water system: Increased from approx. 2.4m3/h to approx. 2.5m3/h, Reactor core spray system: Increased from approx. 1.9m3/h to approx. 2.5m3/h. Unit 2-3 reactor injection water amounts were adjusted as follows.

[Unit 2] Feed water system: Increased from approx. 1.8m3/h to approx. 2.1m3/h, Reactor core spray system: Maintained at approx. 4.0m3/h.

[Unit 3] Feed water system: Increased from approx. 1.7m3/h to approx. 2.0m3/h, Reactor core spray system: Decreased from approx. 4.1m3/h to approx. 4.0m3/h.

What is your Idea about this Water-Levels,
what do you think about the amount of Water
in the cooling circle?

Isn't very low since Months?

Aloha, AC Japan!

Well, maybe the water levels seems a bit low to us but I hope they know what they are doing... we don't know what the cores looks like... probably a very low and flat pile of "glowing" junk... also, I think they try to keep the water feed at a minimum because of the problem to store contaminated water...

N-plant operator questions regulator's assessment

The operator of the Tsuruga nuclear power plant on the Sea of Japan coast has asked a nuclear regulator to explain its assessment that faults running under one of the facility's reactors may be active.

Japan Atomic Power Company on Tuesday sent an open letter to the Nuclear Regulation Authority, saying its assessment is beyond comprehension.

On Monday, an NRA expert panel concluded that so-called crush zones under the Number 2 reactor of the plant in Fukui Prefecture may be active faults.

The firm asked the authority why it concluded that the nearby active Urasoko fault and a fault called D-1 that runs beneath the reactor could move together.

Utility yet to decide on scrapping Tsuruga reactor

The operator of the Tsuruga nuclear power plant on the Sea of Japan coast says it has not decided whether to decommission one of the facility's reactors.

The Nuclear Regulation Authority said in an assessment meeting with experts on Monday that a fault directly under the Number 2 reactor is likely active. The assessment could lead to decommissioning of the reactor. Government guidelines prohibit building key nuclear power facilities above active faults.

TEPCO admits to shady hiring practices at Fukushima nuclear plant

TOKYO — The head of the utility behind Japan’s nuclear crisis acknowledged Monday that hundreds of workers at the contaminated Fukushima Daiichi plant were mobilized through a shady hiring system.

Tokyo Electric Power Co President Naomi Hirose attributed the hiring problem to high worker turnover at the highly contaminated worksite, adding that the problem became prevalent as the company desperately tried to recruit workers willing to take jobs with high risks of radiation exposure.

Japan-U.S. anti-nuclear disaster drill held at Yokosuka base

Japan and the United States held a joint antinuclear disaster drill at the U.S. Navy's Yokosuka base in Kanagawa Prefecture on Tuesday.

The drill was conducted on the assumption that radiation monitoring posts had come to a halt after a major earthquake with its focus on the Miura peninsula near Yokosuka had hit the southern Kanto region.

Doesn't sound very good. Unit 4 at fuku daiichi must
be swaying like a drunken sailor when the eqs hit.
We know there are cracks. Foundations don't usually do well when cracked.

The almost complete lack of information concerning daiini is troubling, no doubt.

I don't like to watch the cams because I think they are doctored..

What are we looking at and what are the implications, in your view..?

This plant had Tritium leaks..
I wonder what they mean when they say they will test the soil to see if it is corrosive..?
Shouldn't that be done before the pipes are buried..?




Indian Point renewal hearing: Judges focus on buried pipes

[snip]

Three federal administrative judges on Monday tried to get a clearer understanding of Entergy Nuclear’s maintenance of the pipes beneath its Indian Point nuclear power plant.

“Without knowing exactly how you’re going to do it, how can we be sanguine” that your management will be adequate, head judge Lawrence McDade asked.

Entergy will also sample and analyze soil around its pipes to determine if it is corrosive.

Good overview.

that is just scary...... where do they store any of this 'leakage'?

In the nearest water source..?

The solution is dilution.

Experts fear more nuke reactors may be sited over active faults

The conclusion suggests, the experts say, that construction of some nuclear plants was approved despite insufficient data that electric companies provided or due to lax oversight of the authorities.

The other five sites are: Kansai Electric Power Co.’s Oi plant in Fukui Prefecture; Hokuriku Electric Power Co.’s Shika plant in Ishikawa Prefecture; Kansai Electric’s Mihama plant in Fukui Prefecture; Japan Atomic Energy Agency’s Monju prototype fast breeder reactor in Fukui Prefecture; and Tohoku Electric Power Co.’s Higashidori plant in Aomori Prefecture.

Gundersen: M7 quake likely caused damage to spent fuel racks at Fukushima Daiichi (VIDEO)

So that was a long prelude to answer your question, why are they building these roofs over the fuel pool? Is that they’re afraid that when they come to pull the nuclear fuel, they’re going to snap some of the bundles and they’re going to release radioactive gases.

This is how close we came..
Could still happen if Unit 4 SFP collapses before they can unload the fuel assemblies.

I don't think people fully realize the precariousness of this situation.
Oh well.. it is what it is. Life goes on.. until it doesn't.



Plant Chief: Fukushima 10 times worse than Chernobyl if containment vessel exploded
[link to enenews.com]

[snip]

If any one of the primary containment vessels had exploded, massive amounts of radioactive material would have been released, and all nine of the other reactors at No. 1 and the nearby Fukushima No. 2 plant would have been unapproachable, Yoshida said.

All 10 would have suffered meltdowns, contaminating the environment far more than the Chernobyl accident did, Yoshida said. [...]

TEPCO PRESS RELEASE (Public domain)

Cesium 134: 3.9x100 Bq/cm3, cesium 137: 7.1x100 Bq/cm3, Manganese 54: 9.8x10-2 Bq/cm3
Upon investigation, the cause of the leakage was assumed to be the header joint part coming off due to the cassette drain valve opening a little when touched.
As a countermeasure, the valves similar to the concerned valve installed in the desalination system (reverse osmosis membrane) 3 have been fixed to be closed at all times with warning signs installed nearby on December 11. At 1:32 PM on the same day, the system was restarted.
-At around 11:08 on December 11, a cooperative company employee found a water puddle on the aisle in the west side of Unit 3 Turbine Building first floor.
At around 11:30 AM on the same day, the leakage was confirmed to have stopped as the filtrate water line valve was closed to check for leakage in the newly installed polyethylene pipe.
The entire aisle was affected by the leakage (approx. 5m x 90m x 10-30mm (depth)) and the leakage amount currently estimated is approx. 13m3.
The leaked water flowed into the feed water heater room on the first floor of the Turbine Building and then into the funnel (pipe going down to the basement), and it has not flowed to the outside of the building.
The radioactivity density analysis results of the leaked water were as follows.

Cesium 134: 4.2x101 Bq/cm3, cesium 137: 7.4x101 Bq/cm3
The densities are lower than that of the accumulated water in the building basement (103 - 104Bq/cm3).
Based on the radioactivity density analysis results and the fact that no leakage was found in the reactor water injection system in the building, the leaked water has been assumed to be the filtrate water used for the fire hydrant. Considering that a pressure hose is connected to the fire hydrant near the large equipment hatch in order to supply water used in the pressure test for the accumulated water transfer pipe and the hose goes through the aisle where the leakage occurred, the leakage location is estimated to be the pressure hose.... yeah.. right...'assumed'....

.... -At 10:55 AM on December 10, a cooperative company employee on patrol found water leakage in the temporary warehouse of the desalination system (reverse osmosis membrane) 3. At 10:55 AM on the same day, the desalination system 3 was suspended and the leakage was confirmed to have stopped. The area affected by the leakage was approx. 4m x 8m x 3mm
