Beijing 2022 conducts water******
BEIJING, Dec. 3 (Xinhua) -- Snow making for Alpine skiing events at the 2022 Winter Olympics is underway in Beijing's Yanqing district and is expected to be completed by mid-January.。
The water needed for snow making at the Yanqing competition zone, where Alpine skiing events will be staged, will account for just 1.6 percent of water used in the area, according to the Beijing Water Authority.。
In the Zhangjiakou competition zone, where freestyle skiing, snowboarding, cross-country skiing, biathlon and ski jumping events will take place, the water demand during the Games will account for 9.8 percent of the total current water consumption in Zhangjiakou's Chongli district.。
"The man-made snow will not affect the local water usage," said Zhao Weidong, a spokesman for the Beijing 2022 organizing committee (BOCOG).。
Competition snow requires a higher density than recreational snow in order to meet the requirements of the FIS, professional skiing's governing body, and to ensure conditions are consistent for each competitor.。
Man-made snow was first used at the 1980 Lake Placid Olympic Winter Games. Around 90 percent of snow used at the Alpine skiing venue for the PyeongChang 2018 Winter Olympics was artificial, while man-made snow was also a feature of Vancouver 2010 and Sochi 2014.。
In line with Beijing 2022's goal of hosting a sustainable and eco-friendly Games, a series of water-conserving techniques have been adopted in snowmaking, according to BOCOG.。
"For Alpine skiing, natural snowfall is incapable of providing sufficient competition snow. Even if the natural snow depth reaches 3m, it can only be compressed into a snow layer of 30cm to 40cm in depth, still far off the requirement for Olympic tracks, which is also one of the reasons why man-made snow has been widely used in snow sports in Winter Olympics worldwide," said Lyu Hongyou, an operations manager at Yanqing.。
Snow-making is not an irreversible consumption of water resources; instead, the snow-melt water can be recycled into reservoirs. Three reservoirs with a total maximum water storage of 160,000 cubic meters can collect the snow-melt and rainwater through conduits in the Yanqing competition zone and pump up the water for snowmaking in the venues, forming an internal recycle of water resources, said Sun Xianghui, an engineer from Beijing Beikong Jing'ao Construction Corporation.。
In the south of Yanqing, a sewage treatment station has been established to process the sanitary sewage from the competition zone into reclaimed water for plant-watering and toilet use, Sun added.。
During the snowmaking process for Beijing 2022 venues, the collected natural precipitation and the overland runoff will be primarily used, and an intelligent system will help decide the timing for snowmaking based on the weather conditions, also in an endeavor to further save water resources and improve efficiency, Zhao said.

Chinese envoy calls for joint efforts to ensure safety of nuclear facilities in Ukraine******
This screen grab taken on March 4, 2022, from a footage of the Zaporizhzhia nuclear authority shows a wide view of the Ukrainian nuclear plant.
A Chinese envoy on Friday called on parties to the Ukraine conflict to act with caution and work together, with the assistance of the International Atomic Energy Agency, to ensure the safety of relevant nuclear facilities inside Ukraine.
China pays close attention to the latest developments in Ukraine and expresses its concern over the relevant reports about the Zaporizhzhia nuclear power plant, said Zhang Jun, China's permanent representative to the United Nations.
According to information the IAEA received from the Ukrainian nuclear authority, the main equipment of the nuclear power plant remains intact, and the level of radiation unchanged. China also takes note of the information and clarification provided by Russia on the relevant matters, Zhang told a Security Council emergency meeting.
Noting the Ukraine crisis is still undergoing complex changes, he said the most important thing right now is to ease tension, avoid more civilian casualties, intensify diplomatic efforts, and get back as soon as possible to the track of political settlement.
Russia and Ukraine have held two rounds of direct dialogue and negotiations and have reached preliminary agreement on setting up humanitarian corridors. China welcomes this and hopes that it can facilitate better protection of civilians and help with the safe evacuation of all foreign nationals, including Chinese nationals, Zhang said.
"We encourage Russia and Ukraine to remain committed to the overall direction of political settlement, and reach a negotiated solution that accommodates the legitimate concerns of the two parties and contributes to Europe's lasting peace and security," he said.
China welcomes all diplomatic efforts conducive to a political settlement, and China has played and will continue to play a constructive role to this end.
The international community should stay cool-headed and rational, and adopt a responsible, impartial and objective attitude in order to create a sound atmosphere and conditions for direct negotiations between the parties concerned, said Zhang.
"Any action must contribute to de-escalation and diplomatic settlement, rather than adding fuel to fire, leading to further escalation and deterioration of the situation."
