Radioactive water leak near Takahama reactor puts planned restart in doubt
Source: Asahi Shimbun
Days before a reactor was to go back online at the Takahama nuclear plant in Fukui Prefecture, a pool of radioactive water was discovered in a building, possibly delaying the reactivation, the plant operator said Feb. 20.
Kansai Electric Power Co. said 34 liters of contaminated water were discovered in an auxiliary structure of the No. 4 reactor building but is not aware of any environmental impact outside the building as a result.
However, the utility did not rule out the possibility of a delay in the resumption of the No. 4 reactor, planned as early as Feb. 26 if all the preparations went well.
We cannot say anything about the effect of the leak on the restart definitively at this point since we are looking into the cause, said a Kansai Electric public relations official.

In fact, two of Takahamas reactors (3 and the currently leaking 4) were both given a no by a local judge, who firmly sided with the people last April.
The new regulations are not reasonable, therefore there is no need to study whether the Takahama plant satisfies them, said Judge Hideaki Higuchi in his ruling. There is little rational basis for saying that an earthquake with a magnitude that exceeds the safety standard will not occur. It is an optimistic view.
However, this temporary victory only slightly postponed the restart of No. 4 at Takahama to 2016. The residents had hoped the decision would reverberate throughout Japan. Activists had anticipated the regulations would mean lengthy legal procedures for any reactor wanting to restart.

(27,509 posts)Radioactive water leak found at Takahama No. 4 reactor, posing restart delay

FADING, IN FUKUI: PAGE 3 Kansai Electric Power Co. said Sunday it has put off preparatory work for restarting of the No. 4 reactor at its Takahama nuclear plant in Fukui Prefecture after a radioactive water leak was discovered a day earlier a move that may delay plans to reboot the unit later this month.

According to the company, an alarm went off after the utility injected water into a pipe connected to the No. 4 reactors first cooling system at around 3:40 p.m. Saturday. Water was found dripping from two valves on a coolant water filter in the auxiliary building, and the radioactivity of the resulting 8-liter puddle was 14,000 becquerels.
Judging from other traces on the floor, roughly 34 liters were leaked overall, amounting to about 60,000 becquerels.
The No. 4 reactor is 30 years old and has idle for more than 4½ years since being taken offline in July 2011 for a scheduled checkup. Thats longer than the No. 3 reactor, which was reactivated in January, and reactor Nos. 1 and 2 at Kyushu Electric Power Co.s Sendai plant in Kagoshima Prefecture, which were rebooted last year.

(20,885 posts)Do they mean water contaminated with radioactive heavy metals?

(27,509 posts)Could be radioactive isotopes of hydrogen, carbon, cesium, etc etc.

(20,885 posts)And I don't think that "heavy water" plays much part in fission reaction. So I expect that these are due to solutes like the ones you mention. Cesium sounds really nasty.
