STAROPRAMEN BREWERY
Experience a must-visit attraction in Prague and learn more about the beer brewing process. Not many people have managed to unravel the mystery of Czech beer, but at the Staropramen Brewery Visitor Centre you will get closer to it. Learn about the history of the brewery, which dates back to 1869, and hear about the current production of Staropramen beer. The day starts with a tasting of delicious beer.

LINE D OF THE PRAGUE METRO – EXCAVATION OF ACCESS TUNNELS IN THE DIRECTION OF PANKRÁC D STATION
Pankrác D Station is designed as a single-vault excavated station with a transverse profile of approximately 350 m2 with three escalator tunnels. The Pankrác Station excavations take place from the PAD1b construction site, which is located at the exit from 5. května Street to Na Strži Street in Prague 4. As part of an engineering-geological survey, a shaft with a net cross-section of 19.2 m and a depth of 27.5 m was dug at this location. During the implementation of the I.D metro, a 200-m-long access and ventilation adit was subsequently driven, which at its end is divided into two branches, Branch A towards the air-conditioning machine room and Branch B towards the future dismantling chamber, where the excavations are currently interrupted. The 50-m-long air-conditioning machine room itself is connected to the tunnelled Branch A. Behind the air-conditioning machine room, there is also a 46-m-long excavated technological link, which is connected to the turning tracks downstream of Pankrác D Station, where excavations are currently underway – first towards Pankrác D Station in a planned length of approximately 70 m and then back towards the dismantling chamber at Branch B of the access and ventilation adit with a planned length of approximately 120 m.

The construction of this important energy source helped to solve both the lack of local electricity production and the difficult ecological situation in northern Bohemia. Thanks to Temelin power plant it was possible to gradually shut down several of the ageing coal-fired power plants.

The technological schema of the power plant corresponds to a standard Gen III power plant. The entire primary circuit (the nuclear reactor, four steam-generators, circulation pumps, etc.) is in a fully pressurized containment facility hermetically enclosed in a protection envelope from reinforced concrete. The reactor core contains 163 fuel assemblies, each with 312 fuel rods, and 61 regulating rods. Each steam-generator produces 1,470 tons of steam per hour with an output pressure of 6.3 MPa and temperature 278.5°C. A turbo-generator with 1,082 MW output is situated in the secondary circuit. The turbine works at a speed of 3,000 turns per minute.

The pressurized-water reactors are fueled by UO2, uranium dioxide enriched to an average of 3.5% of the fission isotope U235. The fuel for Temelin Nuclear Power Plant is currently supplied by the Russian fuel company TVEL.

Along with the Vrané water reservoir, it balances the runoff from the entire Vltava Cascade. It allows for the peak-load operation of the Slapy hydroelectric power station, while it generates semi-peak-load electricity. The operation of the 22.5 MW Štěchovice hydroelectric power station is controlled directly from the control centre at Štěchovice.
The Štěchovice water reservoir was built between 1938 and 1944. The concrete dam with a granite revetment is 22.5 m high and 120 m long, with five spillways with crest gates. These spillways with a capacity of 2,400 m3/s are able to handle floods as catastrophic as the one in 1890.
The medium-head power station is equipped as a classic run-off-river hydroelectric power station, with two sets of Kaplan turbines. It also includes an outdoor 110 kV switching station, and outward distribution transformers.
