一个公民团体已提出紧急请愿书，要求核监管委员会推迟对Seabrook核电站的重新处理，直到原子安全和许可委员会可以审查工厂的具体降解问题为止。

The emergency petition was filed by C-10 Education and Research Foundation, a group of citizen safety experts that monitors airborne radiation near the New Hampshire plant. C-10 filed the petition after the NRC announced it was planning to issue a renewed license and amendment early this year despite a pending hearing with the ASLB this summer on alkali silica reaction (ASR) issues. The NRC completed its review of NextEra’s license application in early December.

The NRC says it is satisfied with a license amendment about how owner NextEra will manage the effects of concrete degradation at the plant based on tests NextEra had run at the University of Texas Ferguson Structural Engineering Laboratory.

NRC Relicensing代理总监Joe Donoghue在2月13日的会议上表示，NRC在发现没有安全问题后，将在2050年向Seabrook Station续签许可证。该工厂在现有许可证上还剩11年。

Donoghue说：“修正案审查花费了两年多的时间，我们认为完成工作，我们可以立即签发许可证。”Nextera表示，它已经致力于对该植物的重新化九年。

But Victor Saouma, a civil engineering professor at the University of Colorado and internationally recognized expert on alkali silica reaction, has reviewed the results of multi-year testing at the University of Texas lab and said in C-10’s petition that NextEra’s and the NRC staff’s conclusions “are not well-founded.” Saouma states that tests run at the lab were “substandard and inadequate.”

In the petition, Saouma voices three major concerns. First, concrete used in the lab is not representative of the concrete at Seabrook, he says. “This lack of representativeness cuts across virtually every level of the test, including characteristics of the materials tested, test conditions and assumptions about the behavior of concrete under finite element simulations.”

He adds that shear tests lack proper boundary conditions. “They are limited to out-of-plane shear and some large unexplained cracks may have corrupted the test results.”

最后，他说使用的裂纹指数测量“无法对原位ASR扩展进行可靠的评估，因为在表面上测得的裂纹指数（混凝土相对干燥）并不能代表样品内部发生的情况。相对湿度（对于ASR必不可少）要高得多。”

Sen. Ed Markey (D-Mass.), whose statement was read at the Feb. 13 meeting, said he is concerned the NRC could prematurely approve Seabrook’s license amendment before the ASLB hearing this summer. He strongly urges the ASLB to hold the hearing before moving forward on licensing.

混凝土退化first discovered in 2009在Seabrook核电站，一直是当地居民的安全关注点。在整个设施的许多建筑物中都发生了ASR裂缝，包括遏制建筑物，柴油发电机建筑物和燃油储存建筑，因为水分与工厂建筑中使用的化学反应性骨料相结合。

A Dec. 14信from an NRC advisory committee to NRC Chairwoman Kristen Svinicki summarized the results of NextEra’s multi-year, large scale testing program at the Texas Lab. “Although ASR causes significant degradation of concrete strength properties as measured by standard core samples removed from ASR-degraded structures, the highly reinforced structures themselves did not experience an associated reduction in structural capacity,” it states.

“In fact, the presence of ASR actually increased the load-carrying capacity of such structures. This was a highly repeatable phenomenon, observed through numerous tests on large-scale specimens, fabricated with concrete intentionally subjected to accelerated ASR, well beyond the levels observed to date at Seabrook. Testing included shear capacity tests, reinforcement anchorage and beam flexure tests, as well as concrete anchor pullout tests in ASR-affected concrete.”

Nextera发言人彼得·罗宾斯（Peter Robbins）表示，尽管存在混凝土降解，但Seabrook站的发电厂和结构是合理的，并且完全有能力执行其设计功能。“ ASR是众所周知的，易于管理的条件，经过八年的技术评论，NRC发现我们长期监视和管理ASR的计划有效。

He added that NextEra opposes the C-10 petition. “We see it as a last-minute and desperate attempt to upend the NRC’s process for license renewal.”

NRC发言人说，该委员会无法估计应对紧急请愿书需要多长时间。
