Stress tests: The Authority's analysis completed

日本の政治家に是も読んで欲しい。いまだに江戸時代みたいに悪代官が自分の利益のためだけに動いて
日本の本当の将来の存続のために生涯を捧げていない。寺子屋にもう一度そういった人たちは入りなおして道徳を勉強しなおすべき。先祖がくれた美しい国を、海の幸や山の幸を愛してきた我々の国を汚してしまった人たちは、本当に国を思う専門家の意見を無視して、自分たちの今の利益のみを考える人たち。エゴは国を豊にするどころか、砂上の楼閣のように国を滅ぼす。将来の日本の存続のためには、きっぱりと核をやめて、武士のように潔く、エネルギー政策を転換し、世界のエネルギー先進国たるべく努力をいちから始めればいい。ドイツに学んできた我々は、どうして今自国での原発をやめて、負の遺産をおもりしながらも、新たに模索するといった行動を今とらないのだろうか。占い師の女性のことばは、気つき。何かに気がつくことが必要という。我々に知らしめられたことに多くの人に気がついている。
政府がいい加減だと、経済発展以前に多くの罪のない人間が無駄に死んでしまう。理念ある政治家はどこにいるのだろうか。国を救えるリーダーたちの理念と勇気ある行動が待ち望まれる。

The Swedish nuclear power plants are robust and resistant against most extreme events, but for some events it becomes necessary improvements. Nuclear power plants are not fully dimensioned to handle an accident scenario where multiple reactors are knocked out simultaneously and for lengthy events. The assessment is made by Radiation Safety in its analysis of the nuclear installations stress tests.

Now the Radiation Safety Authority reviewed the nuclear plant and the central interim storage facility for spent kärnbränsles (CLAB) final reports of stress tests.

- The stress tests are an important contribution in efforts to improve security at the Swedish nuclear power plants. We have identified several areas where it is necessary to conduct further analyzes. However, our overall assessment is that the Swedish plants are robust and there is no reason for us to impose some restrictions on the operation of the facilities, said Jan Hanberg, project manager for the stress tests and the Chief of the Radiation Safety.

A strength is that all Swedish reactors have breakdowns filter that allows the radioactive substances are filtered out at a discharge. This means that the impact on the environment is significantly reduced in an accident. Wreck The filters were installed after the nuclear accident in Three Mile Island (Harrisburg).

Deviations from the applicable requirements

In a few cases the stress tests to deficiencies in relation to or deviations from the applicable requirements for safety analysis.

- It shows how important the work of the stress tests have been. We will in these cases to impose the license holders to take action that makes the plants meet current requirements, says Jan Hanberg. Take, for example if we want to see more detailed analyzes of how the reactors can withstand earthquakes.

Accident management must be improved

But if what in Japan is an accident in which several reactors are affected simultaneously shows the stress tests the readiness of the facilities are not designed for such a scenario.

- In such a scenario, it is not certain that the resources used for the entire plant is adequate, for example, fire intensity, the joint command center and staff. In addition, nuclear power plants further investigate the failure of the filters function in an extended course similar to what happened in Japan, says Jan Hanberg.

The stress tests also show that the reserve force and the systems to deliver water from the plant needs to be further strengthened. Take, for example on another system that is independent of the existing reserve power, to pump water to cool the core and more mobile diesel generators.

Resistance to earthquakes must be further analyzed

In Sweden, only the youngest two reactors, Forsmark 3 and Oskarshamn 3, which was originally designed to withstand earthquakes. For the other reactors, the demands made after the fact. Now consider that the Radiation Safety analyzes for the older reactors need to be supplemented further to find out if they fully withstand a major earthquake.

In the statements that the facilities left the ice storms have not been analyzed in detail.

- We will require that licensees of the facilities to analyze the implications of ice storms and propose measures, says Jan Hanberg.

Facts

By 31 December leaving the Swedish Radiation Safety Authority report to the European Nuclear Safety Regulators Group (ENSREG).

This spring, a specially appointed group of international experts, called a peer review team, review country reports.

In June presents the results of stress tests for the European Council.
