Move over, three fuel assemblies with damaged/deformed fuel rods inside in the Reactor 4 Spent Fuel Pool! You're nothing.
According to Kahoku Shinpo, a Fukushima local paper, TEPCO admitted on November 15, 2013 that there are 70 fuel assemblies with damaged fuel rods in the Reactor 1 Spent Fuel Pool, located on the operating floor (top floor) of the reactor building whose air radiation levels are measured in millisievert/hour and sievert/hour (first floor).
There are also three such fuel assemblies in the Reactor 2 SFP, and four of them in the Reactor 3 SFP.
Total 80 spent fuel assemblies in the SFPs in Reactors 1 - 4 are damaged.
The damages had been there long before the March 11, 2011 accident, and TEPCO claims it properly notified the national government as they discovered the damages. But the company has come clean in public only now.
Kahoku Shinpo article below suggests that the oldest of such damaged fuels may have been there for 40 years in the Reactor 1 Spent Fuel Pool. (Reactor 1 started generating electricity in 1971.)
Reactor 1 at Fukushima I Nuke Plant is TEPCO's oldest nuclear reactor; it was entirely the project by General Electric of the US, a turnkey.

#Fukushima I Nuke Plant: TEPCO Admits Total 80 Spent Fuel Assemblies Had Damages Before the Nuclear Accident, 70 of Them in Reactor 1 Spent Fuel Pool
Move over, three fuel assemblies with damaged/deformed fuel rods inside in the Reactor 4 Spent Fuel Pool! You're nothing.

福島第１原発１号機 燃料震災前破損７０体 全体の４分の１
Fukushima I Nuke Plant Reactor 1 has 70 fuel assemblies damaged before the March 11, 2011 disaster, a quarter of the total spent fuel assemblies [in the Spent Fuel Pool of Reactor 1]
福島第１原発１号機の使用済み燃料プール内にある燃料棒７０体が東日本大震災前から損傷していたことが１５日、分かった。
It was revealed on November 15 that 70 fuel assemblies in the Reactor 1 Spent Fuel Pool at Fukushima I Nuclear Power Plant had had damages before the March 11, 2011 earthquake/tsunami.
プール内に保管されている使用済み燃料２９２体の４分の１に相当する。損傷した燃料棒を取り出す技術は確立しておらず、２０１７年にも始まる１号機の燃料取り出し計画や廃炉作業への影響が懸念される。
The damaged assemblies are about one-quarter of the 292 spent fuel assemblies stored in the pool. Technologies to remove damaged fuel haven't been established, and there are worries that [the revelation] may negatively affect the plan to remove the fuels from Reactor 1 [SFP] starting 2017 and the decommissioning work in general.
東京電力は、１５日まで事実関係を公表してこなかった。同社は「国への報告は随時してきた」と説明している。
TEPCO hadn't disclosed all the facts until November 15. The company says it had reported to the national government as required.
東電によると７０体の燃料棒は、小さな穴が空いて放射性物質が漏れ出すなどトラブルが相次いだため、原子炉から取り出してプール内に別に保管していたという。
According to TEPCO, these 70 fuel assemblies had series of problems including leakage of radioactive materials from small [pinhole-size] holes [on fuel rods]. So the company removed them from the reactor and stored in a separate location inside the Spent Fuel Pool.
１８日に燃料取り出しが始まる４号機プール内にも損傷した燃料棒が３体あり、東電は通常の取り出しが困難なため、対応を後回しにしている。
There are three damaged fuel assemblies inside the Reactor 4 Spent Fuel Pool, where the removal of the fuel assemblies will start on November 18. TEPCO has postponed the removal of the damaged assemblies as it is difficult to remove them in a normal manner.
損傷した燃料棒は１、４号機プールのほかにも２号機プールに３体、３号機プールに４体の計８０体ある。東電は専用の輸送容器を新たに製造するなど対応策を検討する。
Other than in the Spent Fuel Pools of Reactor 1 and Reactor 4, the Reactor 2 Spent Fuel Pool has three damaged fuel assemblies, and the Reactor 3 Spent Fuel Pool has four, making the total of damaged fuel assemblies 80. TEPCO will consider the measures such as building a dedicated container for transfer for these damaged fuels.
損傷燃料が１号機に集中している理由について、東電は「１号機は当社で最も古い原発で、燃料棒の製造時、品質管理に問題があり粗悪品が多かったと聞いている。２号機以降は燃料棒の改良が進み、品質は改善した」と説明した。
As to the reason why Reactor 1 has the largest number of damaged fuels, TEPCO says, "Reactor 1 [at Fukushima I Nuke Plant] is the oldest nuclear reactor of our company, and we hear that there were quality control issues when the fuel rods were manufactured and that there were many fuel rods with inferior quality. From Reactor 2 onward, much improvement was done on the fuel rods, and quality improved."
１号機は東電初の原発で、１９７１年３月に商業運転を開始した。
Reactor 1 at Fukushima I Nuke Plant is the first nuclear reactor for TEPCO, and it started the commercial operation in March 1971.
No major national newspaper has covered this story so far.

Tepco practiced the disaster drill for emergency of reactor4 pool fuel removal. They were stating the fuel won’t reach the critical state or affect the outside of the plant area.
They are going to start the fuel removal of reactor4 pool from next week.
The disaster drill was practiced from 10/25/2013.
[Video] Reactor1 confirmed leaking out the coolant water / 2.0 Sv/h

Fukushima Diary has been suggesting the possible direct leakage of contaminated water from reactor1 to underground.
(cf, [Column] Tepco may be hiding the possible direct leakage of coolant water – Press should demand disclosure [URL])
From 11/13 to 11/14/2013, Tepco investigated the basement floor of reactor1 building to identify 3 locations of the leakage from PCV.
They used the remote controlling boat for this investigation.
The leakages are the from a vent pipe and also a crippled sand cushion drain pipe around the suppression chamber. A part called sand cushion ring header was also observed leaking.
The ambient dose was 0.9 ~ 2.0 Sv/h. The leakage speed wasn’t tested.

Another leakage of contaminated water tank was found on 11/15/2013. A sub-ordinate company worker found it in the patrol.
The radioactive densities of the tank water are
All β (Including Strontium-90) : 78,000,000,000 Bq/m3
Cesium-134 : 1,500,000 Bq/m3
Cesium-137 : 2,700,000 Bq/m3
Tepco assumed the leakage point was one of the bolts, the volume of leaked water was 11 L. They didn’t find the leakage one day before.

Unit 4 Fuel Removal May Start Monday
According to a document TEPCO released this week, as long as third party inspections are passed Thursday and Friday work to removal fuel may start on Monday. A dry run of cask handling was done on November 13th along with a mock fuel removal using “simulated fuel”. TEPCO has outlined a bit more about processes and safety mechanisms put in place. TEPCO did have training time blocked off in the schedule, so some sort of unified … Read entire article »
Unit 1 Leaks Found; We Have The Details
TEPCO has investigated the torus room of unit 1 with the new boat robot. This was an effort to look closely at the downcomer pipes that run to the torus and the related structures. They did find leaks at two locations on the first half of the investigation. One is a leak that appears to be near the ceiling and … Read entire article »
Hey Fred, We won the game and it was fairly warm, just rained the whole time. Thank goodness for those dollar disposable plastic rain coats, I'm going to be stocking up on those things.
ReplyDeleteWow the mistaken beheading was interesting, saw a picture that showed the victim having his head held up and a picture that showed him holding someone else's head, if real what an amazing display of karma.
Of course I knew that everything the government has done they have done to bail out the bankers.
Oh, an interesting benefit to me personally from Obama care. Evidently the increase is going to be so bad at my company (my boss didn't know the amount of increase yet, HR will probably wait until the last minute of 2013) that the PTO policy is going to be changed so that we will accrue more time off. My company is very tight with a buck when it comes to employees, so the increase must be horrendous if they are giving us a new benefit.
Morning Kev ! Glad to hear the weather was warmer ( even with rain ) for the football game !
ReplyDeleteThe accidental beheading piece was interesting and yes , karma did kick in for the " victim " . Supposedly , the victim when captured thought he was captured by Shia forces ( so he tried to trick his captors by saying prayers which would imply he was Shia - obviously , that was the wrong move . For any of the jihadist rebels who have committed atrocities , live by and die by the sword , right ?
ObamaCare resulting in some additional time off ( and from a skin flint boss at that ) , yeah , you are about to be tommy hammered , buddy !
