Everything about nuclear energy seems terrifically big: the cost, construction and decommissioning—and the fears of something going badly wrong.
The future, however may well be much smaller. Dozens of companies are working on a new generation of reactors that, they promise, can deliver nuclear power at lower cost and reduced risk.
These small-scale plants will on average generate between 50MW and 300MW of power compared with the 1,000MW-plus from a conventional reactor. They will draw on modular manufacturing techniques that will reduce construction risk, which has plagued larger-scale projects. Supporters believe these advanced modular reactors (AMRs)—most of which will not be commercial until the 2030s—are critical if atomic power is to compete against the rapidly falling costs of solar and wind.
“The physics hasn’t changed. It’s about much cleverer design that offers much-needed flexibility in terms of operation,” said Tim Stone, long-term industry adviser and chairman of Nuclear risk Insurers, which insures nuclear sites in the UK.
Since the Fukushima meltdown in Japan in 2011, safety fears have threatened nuclear power. But the biggest obstacle today is economic. In western Europe, just three plants are under construction: in the UK at Hinkley point in Somerset; at Flamanville in France; and at Olkiluoto in Finland. All involve the European Pressurized Reactor technology of EDF that will be used at Hinkley Point. All are running years late and over budget. In the US, the first two nuclear projects under way for the past 30 years are also blowing through cost estimates.
The UK, which opened the world’s first commercial nuclear reactor in 1956, is one of the few western nations committed to renewing its ageing fleet to ensure energy security and meet tough carbon reduction targets. It is seen as a proving ground, by many in the industry, of nuclear power’s ability to restore confidence.
However, the country’s agreement with EDF to build two units at Hinkley Point—which together will generate 3.2GW of electricity—has come under severe criticism over its cost. The government is looking at different funding models but said it still sees nuclear power as vital to the country’s future energy mix. Small reactors, it believes, have the potential to generate much-needed power from the 2030s.
A nuclear sector deal, unveiled last month, promised up to ￡56m in funding for research and development into AMRs and attracted interest of start-ups from around the world. The government hopes the funding will give the UK a lead in the global race to develop these technologies, helping to provide energy security while also creating a multibillion-dollar export market for British engineering companies.

As smog forced students to stay home, the online learning industry saw a sharp increase in consumers.
During the air pollution red alert from Dec. 8 to 10 last winter, the Beijing Commission of Education ordered all kindergartens, primary schools and middle schools to suspend classes (停课). But the commission urged that, "Teachers should guide students to make full use of digital materials and conduct online learning at home".
According to the China Education and Research Network, the number of new users of 17zuoye. com, an online homework platform, tripled (增至三倍) on Dec. 8 compared to the previous day.
Online courses companies also adopted special measures to meet students' demand for Internet learning during the red alert period. For example, New Oriental offered free online English classes for three days for school students as well as online question answering services.
Recent years have seen the popularity of online courses increase sharply in China. Massive Online Open Courses (MOOC), for example, originated in the United States but have become widespread in China since 2013. Some Chinese universities, including Tsinghua University and Peking University, have started their own MOOC platforms. "MOOCs have enlarged the time and space of teaching, fired up learners' interest, helped more people benefit from high quality educational resources and accelerated reform in many aspects of teaching," an official at the Ministry of Education told China Daily.

Visit the Newseum During “Museum Day”！
Museum Day is an annual celebration of boundless curiosity hosted by Smithsonian magazine. Participating museums and cultural institutions across the country provide free entry to anyone presenting a Museum Day ticket. The Museum Day ticket provides free admission for two people.
Here is some information about a popular museum — the Newseum.
EVENT DETAILS
Registration: free tickets will be available for the public to download on December 15 via the link : https ://www. smithsonianmag. com/museumday/museum-day-2018/.
Advanced registration is requested so that the museum sites know how many people to expect. If you don't register beforehand you may still be admitted the day of the event, but no guarantee for admission. All are welcome to attend including children and groups.
Meeting Point #1: From 7:45 – 8:00 some volunteers will be in the Starbucks at 325 7 th St NW before walking 2 blocks to the Newseum.
Meeting Point #2: Outside the Newseum’s Pennsylvania Avenue entrance. The Newseum opens at 9:00 am. However, as this is an extremely popular event we highly recommend arriving as early as possible, by 8:15 if you can, to bypass the masses that will show up later in the day.
Meeting Point #3: Once the museum opens we recommend immediately heading to the 6th floor to avoid the masses since most people start on the 1st floor. On the 6th floor, the Hank Greenspun Terrace, which overlooks Pennsylvania Avenue and the U. S. Capitol, has one of the best views in Washington, DC. After that you can proceed through the museum’ s exhibits starting on the 6th floor and working our way down. The Newseum is open until 5:00 pm and guests are free to arrive and depart whenever they like.

A Few Active Listening Guidelines
Listening is arguably the most important element of interpersonal communication. Our ability to listen well impacts the quality of all of our relationships, and not just at home with our family and friends—it can also affect our relationships and interactions on the job, as well as the effectiveness and quality of our work.
1. Instead, it is a skill that must be cultivated and practiced. Active listening means the difference between simply hearing, and listening with the intent to truly understand. It is a subtle but important distinction.
1. Give focused attention.
Try to minimize external (外部的) distractions. Turn down the noise, and put down or step away from what you’re doing if possible. 2. Don’t watch the clock, fidget (坐立不安) or go over your to-do list for later.
2. 3.
Direct eye contact shows your attention and intention to listen. This doesn’t mean stare, though. Be reasonable, but try not to let your eyes wander to whatever is going on around you.
3. Reflect back.
Restate, but don’t repeat word for word. Paraphrase what you think the other part is saying with responses such as: “What I’m hearing is…” or “Let me see if I’m following you... ”4.
4. Respond appropriately.
Be open and honest in your responses. Share your thoughts, insights and feelings in a clear, but respectful and considerate manner even if you disagree.
Active listening is a model for good communication. 5. It takes practice to develop active listening skills, and it’s a habit that has to be reinforced（加强）. Remind yourself that the goal of conversation is not merely to trade words, but to truly understand what the other party is saying and to be understood in turn.
A. Maintain eye contact.
B. Instead, focus on what is being said.
C. You do not have to agree on everything.
D. Also, set aside other internal thinking and dialogue.
E. Listening is not something that comes naturally or easily for most of us.
F. Reflecting what you’ve heard signals that you’re attempting to understand fully.
G. Remember that listening is not just to gather information and share ideas, but also to gain perspective and understanding.
