A Chinese atomic energy official said the country will fine tune its nuclear energy safety standards, develop its emergency response system and improve the management of spent fuel.

Wang Yiren, vice head of the State Administration of Science, Technology and Industry for National Defence, told Xinhua that during the 13th Five Year period (2016-2020), China will undertake a number of nuclear-related projects.

Research into the processing of spent fuel will be conducted, according to Wang, who is also deputy head of China Atomic Energy Authority.

In response to concerns over the safety of inland nuclear power projects, Wang said such worries are understandable, but assured that the projects would be secure.

As energy demands in inland regions have increased, the need for inland nuclear power projects has increased, he said.

Wang said the authorities have also organized expert discussions on the construction of nuclear power stations at sea, to support offshore oil and gas exploitation and the country’s islands.

The official also pledged efforts to ensure the supply of uranium resources and nuclear fuel for nuclear energy development.

Twenty five people have been arrested in two separate instances of fly-tipping, in which more than 100,000 tonnes of garbage was carelessly dumped last year, the People’s Procuratorate of Zhejiang Province in east China said Tuesday.

The 25 suspects have been implicated in two cases that occurred between May and December last year.

In one case, over 90,000 tonnes of household trash from Haiyan County, Zhejiang, was either dumped at sites across the provinces of Zhejiang and Anhui, or thrown into the Nantong section of the Yangtze River in east China’s Jiangsu Province.

In the other case, more than 10,990 tonnes of trash from Haining City, Zhejiang, was collected and 9,747 tonnes of it was dumped into the Yangtze River between November and December, causing serious water pollution and economic losses of over 300,000 yuan (about 43,725 U.S. dollars).

The investigation continues.

Local police officers shot and killed three rioters armed with knives that attacked and injured 10 people in a residential community in Pishan county in the southwest part of the Xinjiang Uygur autonomous region, on Tuesday evening, according to xjht.gov.cn, a news portal run by the local government.

Five of the 10 people injured by the mob died later in hospital. The rest are being treated. The rioters had earlier stormed the residential community and hacked randomly at residents. An investigation is under way.
