一家加州公司同意支付590万美元解决核电站环境损害问题

2021-6-25 16:46


新华社洛杉矶6月24日电-美国加州太平洋天然气和电力公司(PG&E)近日就一份价值590万美元的美国天然气合同达成协议。该公司的代阿布洛峡谷核电站的一次性冷却水排放费用为1美元。


达成的和解协议,与中央海岸地区水质控制董事会,是彻底的结果水董事会调查违反源于植物的用水来自太平洋的冷却系统自1985年以来,5月25日正式提交圣路易斯奥比斯波高等法院。


根据加州海岸新闻周四的报道,核电站在经过两个发电机的“一次通冷”过程后,从海里吸收水来冷凝蒸汽,然后用过的水再释放回海里。


根据该发电厂的当地许可,公共用水可以通过管道从附近海域流入海洋,但环保人士辩称,向海洋排放水会损害海洋生物。


中央海岸区域水质控制委员会发言人艾琳·沃森据估计,该地区的热排放比周围海洋温度高约20华氏度(11.1摄氏度),对附近生态系统的改变“已得到充分记录和理解”,但“没有可行的技术替代或修改”。


另一个问题是,从代阿布洛峡谷抽水到发电厂的诱导系统每年还会吸收大约15亿条鱼苗,从而破坏当地鱼类的繁殖循环。


水务委员会在6月18日的一份新闻稿中表示,从PG&E获得的结算资金将用于有利于该地区的水质项目。


除了和解之外,声明还表明PG&E还每年支付一笔款项,以缓解过热排放带来的问题。

LOS ANGELES, June 24 (Xinhua) -- California's Pacific Gas and Electric Company (PG&E) has agreed recently on a 5.9-million-U.S.-dollar settlement for once-through cooling water discharges from its Diablo Canyon nuclear power plant.

The settlement, reached with the Central Coast Regional Water Quality Control Board, was the result of a thorough Water Board investigation into alleged violations stemming from the plant's use of water from the Pacific Ocean in its cooling system since 1985 and was officially filed on May 25 with the San Luis Obispo Superior Court.

According to Thursday's report by Cal Coast News, the nuclear power plant takes in water from sea to condense steam after it passes through two electrical generators in a process called "once-through cooling" and the used water is then released back into the ocean.

Under the power plant's local permit, public water was allowed to be piped from nearby sea area into the ocean, but environmentalists argued the discharge of water into the ocean harmed marine life.

Ailene Voisin, spokesperson for the Central Coast Regional Water Quality Control Board, estimated the thermal discharge to be about 20 degrees Fahrenheit (11.1 degrees centigrade) above the ambient ocean temperature in that area and that alterations to the nearby ecosystem "are well-documented and well-understood," yet with "no feasible technological alternatives or modifications."

Another problem was that the induction system that pumps water from Diablo Canyon into the power plant also sucked up an estimated 1.5 billion fish larvae per year, causing disruptions to the reproductive cycle of local fish.

The Water Board said in a press release on June 18 that the settlement funds received from PG&E would be used for water quality projects that benefit the region.

In addition to the settlement, the release indicated that PG&E had also been making yearly payments to mitigate the issues from their overheated discharges.
