The Mühleberg nuclear power plant is strangled by heat

The Mühleberg nuclear power plant in the canton of Bern has to reduce its production by about 10 %. The reason is the high temperatures of the Aar, whose water is used to cool the nuclear reactor.

If Aarewater has a daily average of more than 20.5 degrees Celsius, the performance must be limited, as announced Friday the BKW operating company. About throttling had first reported 20Minuten.ch. The power reduction is regulated in the concession, which is necessary for the use of water from the Aare.

The throttling is not unusual in the summer, said BKW spokesman Tobias Habegger. "Already in early July, we reduced reactor production for the first time through the concession of cooling water.In the meantime, the reactor could also run for longer periods with 100 percent power." necessary, the power is adjusted several times a day.The limitation has no effect on the power supply in the FMB area.BKW produces more electricity than the customers consumed, says Habegger

Prohibition of burning in the canton of Zurich

The danger of forest fire in the cantons concerned is mainly at level 4 of 5 (large), so that forest fires near the forest were needed. This was announced by the respective cantonal authorities. These justified the bans also by the fact that no lasting rain is foreseeable.

Bans apply to the forest as well as to a radius of 200 meters around the forests – this corresponds to a distance of about two football fields (length). In this perimeter, it is forbidden to burn fireworks or fire.

In addition to Zurich also imposed Appenzell Innerrhoden and Glarus on Friday, a fire ban in the forests and near of the forest. The fireworks fire is also prohibited throughout the canton of Glarus – and this also on August 1.

The City of Bern has announced that the traditional fireworks of the National Day will be canceled due to the danger of fire this year. The Bernese must abandon this year a bonfire on the mountain of Gurten.

On Thursday, six townships issued a fire ban in and near forests. They joined a large number of cantons who had already taken action earlier. In Valais, in Ticino and in the southern valleys of Graubünden, an absolute ban on making fire has existed for days

Sale of sales to major distributors

Major Migros and Coop distributors also reacted to the prohibitions. In most cantons without fire, there are no rockets, cannons, volcanoes and others to buy in the branches on August 1st.

The fireworks are now on the shelves of Migros Eastern Switzerland, as Nico Canori Keystone-SDA request said. But this is now canceled due to the situation in the cantons in the catchment area. Canori confirmed Thursday the corresponding information from the "Lake Zurich newspaper".

For measurement, the decommissioning ban is crucial and also the weather forecast, which promised no improvement. Security has priority. According to Canori, there was a similar measure last year: at that time, several branches in Graubünden would have given up the sale of fireworks.

Coop said that the sale would be stopped – as had been done in recent years – in areas where a burn-off prevails. Coop wants to help prevent possible damage caused by fire or fireworks.

"It begins to slow down, to slow down"

The heat also causes more and more problems to the fish of the Rhine near Schaffhausen. Until now, only a few dead fish have been found in the Rhine, said Schaffhausen Fisheries Inspector, Patrick Wasem, on request. "But things are starting to tighten." The situation is tense.

From 23 degrees, the shadow begins to show symptoms of wasema and, most importantly, looks for shady spots. From 24 to 25 degrees, it would be difficult for the fish. At Neuhausen SH, the temperature of the Rhine reached Wednesday a maximum of 25 degrees C.

A handful of cooling zones, dug at the mouth of the creek, have somewhat helped. Fish can take refuge in colder waters if the Rhine becomes too hot for them. These areas are the consequence of the heat of the summer of 2003, when almost all the shadow of Stein am Rhein and Schaffhausen is dead. (NN / sda)
