San Antonio, TX —  Nuclear power is the most water intensive energy source available. When San Antonio and all of Texas are suffering from extreme drought and are increasingly in need of sources of drinking water, pursuing more nuclear reactors doesn’t make sense, especially true since cheaper, safer alternatives such as energy efficiency, wind, geothermal and solar energy are available. All use significantly less water than nuclear reactors.

Dr. Lauren Ross’ comments are timely in that the Texas drought continues to worsen, and the Atomic Safety and Licensing Board is still considering nine water-related contentions submitted in opposition to additional reactors by SEED Coalition, Public Citizen and STARE, the South Texas Association for Responsible Energy.

“Nuclear reactors consume vast quantities of water,” said Dr. Lauren Ross, environmental engineer and owner of Glenrose Engineering. “The proposed STP reactors 3 and 4 would withdraw 23,170 gallons per minute from the Colorado River. The two proposed reactors would increase forced evaporation by an additional 37,400 acre-feet per year. The water withdrawal required from the Colorado River to replace evaporated water for all four reactors would be about 74,500 acre-feet per year.”

“Water withdrawal for STP’s nuclear reactors can be a significant fraction of the total river flow. Peak water use so far occurred on September 16, 2001, when the water withdrawal was 48% of the total Colorado river flow near the reactor site,” said Dr. Ross. “From January 1, 2001 through September 30, 2006 there were 69 days when withdrawal for existing STP reactors was equal to or greater than one quarter of the entire river flow.” With four reactors and an increase in the surface water demand, the river flow in the future could go even lower than it is now.

Estimated groundwater use would more than double from an average of 798 gallons per minute for the existing facility over the last five years to a level of 2040 gallons per minute for all four reactors, according to Dr. Ross, but STP wants to wait on analyzing groundwater availability until after the permit is issued.

The year 2008 was one of the driest years on record for Central Texas. Dr. Ross’s most recent research shows that in 2008 water use by LCRA’s firm water customers plus four irrigation operators was more than twice that of the Highland Lakes inflows for the same period, so losses are not being replenished. Moreover, STP’s authorized withdrawal is more than one-third of the total Highland Lakes inflow for 2008.

Water versus Energy

The San Antonio Water System recently filed suit for breach of contract against the Lower Colorado River Authority for $1.23 billion. The suit claims that the water-sharing project was killed by the river authority in order to make sure there would be enough water for power plant deals in Matagorda County. At the same time CPS Energy, the San Antonio municipal utility, seeks to be a partner in the proposed nuclear reactors for Matagorda County. STP’s annual permitted withdrawal from the Colorado River is 102,000 acre-feet per year, incredibly close to the amount in the canceled LCRA/SAWS water agreement, 102,500 acre-feet per year (average).

“Will we reach a point where San Antonio will have to decide which matters most, electricity from nuclear reactors or water for drinking?” asked Alice Alice Canestaro-Garcia, visual artist and member of EnergÍa MÍa. “It makes no sense to build two more reactors, which together would use enough water to fill 1,440 swimming pools in one day.”

Increasing Radioactive Contamination

South Texas Project’s license application fails to evaluate the increasing levels of groundwater tritium, a radioactive isotope of hydrogen that can be dangerous if inhaled, ingested or absorbed through the skin. Tritium emits Beta radiation that causes cancer, cell mutation, and birth defects. “Tritium has been detected in two of the pressure relief wells that collect water leaking from the unlined bottom of the existing main cooling reservoir. Concentrations of tritium have been increasing in both wells, and these concentrations could rise if two more nuclear reactors are built at the site,” said Dr. Ross.

A state water permit proposed for the site fails to address radionuclides such as tritium, and doesn’t require monitoring for total dissolved solids, some metals or the chemicals added by the facility, such as biocides, sulfuric acid, and anti-scalants. There are also no sulfur or sodium limits for the wastewater discharges, even though these are significant components of the water that would be released back to the Colorado River system.

The application’s Environmental Report relies upon a dilution factor of 10 to meet discharge standards, but fails to provide information about how much the waste discharge loads would change with two additional nuclear reactors. It fails to analyze the consequences of the load increases into a system with only a small change in the dilution factor, since the storage volume would increase only 7.4%.

The reactor application admits that “5,700 acre-feet per year leaks through the unlined bottom of the main cooling reservoir into the underlying Gulf Coast Chicot Aquifer” and 68% of it is recovered. The rest migrates underground, seeping into nearby surface water bodies, into pumped wells or the estuaries of the Gulf of Mexico.

“Failure to monitor and regulate leakage through the bottom of the main cooling reservoir constitutes a failure to protect groundwater and surface water from plant operations,” said Dr. Ross.

UPDATE: Safety panel hearing in the news: at the Houston Chronicle and the San Antonio Express News

Citizen opposition to two proposed nuclear reactors at the South Texas Project continues with another success. On August 27th the Atomic Safety and Licensing Board (ASLB) Panel found that the nuclear applicant, South Texas Project Nuclear Operating Company (STPNOC), had failed to adequately analyze issues raised by concerned citizens in their Petition to Intervene in the proposed expansion at STP.

“This is a major victory for those living in the South Texas Project region and throughout Texas,” said Karen Hadden, Executive Director of the SEED Coalition. “The decision recognizes that the South Texas Project reactor application is still inadequate, two years after it was submitted. We now have a case against the reactors that will move forward.”

SEED Coalition, Public Citizen and the Bay City based South Texas Association for Responsible Energy (STARE) are Intervenors in the case. Attorney Robert V. Eye went before the ASLB Panel in June and argued the admissibility of 28 contentions challenging the license application for two additional reactors, Units 3 and 4, at the South Texas Project. The ASLB Panel has ruled on 19 of the 28 contentions submitted and found that one of the contentions deserved further inquiry, giving Intervenors a case against the reactors. It is not known when a decision will be made on the remaining contentions.

“South Texas Project’s reactor application is seriously flawed.” said Mr. Eye. “They failed to analyze how a severe radiological accident or a major fire or explosion at any of the four units would impact the other remaining units at the site. This is a major omission and the issue should have been considered by STP.” The contention reads:

Contention 21 – Impacts from severe radiological accident scenarios on the operation of other units at the STP site have not been considered in the Environmental Report.

“A radiological accident at one unit could cause impacts and disruptions in operations at the other units,” said one of the Intervenors, Bill Wagner, a former STP Operations Supervisor. “How would operations at undamaged units continue in the event that the entire site becomes seriously contaminated? STP needs to address this.”

Water Issues Are Yet to be Decided

The ASLB panel delayed a decision on all nine of the Intervenors’ contentions that deal with water issues. The issues yet to be ruled on include: the build-up of radioactive particulate in STP’s Main Cooling Reservoir (MCR), increasing levels of groundwater tritium, the vulnerability of the MCR to flooding, insufficient limits on toxic discharges, reliance on dilution to achieve discharge standards, unregulated wastewater discharge, unevaluated reduction in groundwater supply for adjacent landowners, unevaluated reduction in surface water flow, and inadequate supplies of fresh water due to global warming impacts.

“Nuclear plants consume enormous amounts of water and are vulnerable to shutdown during drought and reduced river flows. The two proposed reactors would use over 23,000 gallons of water every minute.This is a real one-two punch. Not only would STP’s operations reduce water supplies for cities like Austin or San Antonio, but the plant might not even be able to operate if the Lower Colorado River has severely reduced flows from drought,” said Hadden. “These problems don’t exist for wind, solar and geothermal sources to generate electricity.”

“The current water shortages in our area are hitting us hard,” said Susan Dancer, a local wildlife rehabilitator and Chair of South Texas Association for Responsible Energy. “Livestock suffer since hay and other feedstuffs are in incredibly short supply and there is no grass left. We have personally spent over $5000 this summer having hay trucked in from other areas on semis and have gone deep into debt trying to keep the livestock fed and healthy. Everyone here is in the same situation, so selling off stock is not an option. Prices are at all-time lows due to the large number of producers who are dumping stock at the markets already.”

“Texas is in a Stage 4 drought and has been declared a disaster area. The Texas Department of Agriculture says there are no programs available to assist us,” said Dancer. “Granting more water to industry, especially nuclear reactors that consume vast quantities of water, is not an option. This drought and others to come may be even worse.”

When it comes to water, San Antonio and Central Texas citizens are feeling the pain as well. On Monday, the San Antonio Water System filed suit for breach of contract against the Lower Colorado River Authority for $1.23 billion. The suit claims that the water-sharing project was killed by the river authority to make sure there would be enough water for power plant deals in Matagorda County. At the same time CPS Energy, the San Antonio municipal utility, seeks to be a partner in the proposed nuclear reactors for Matagorda County. Will San Antonio have to decide which matters most, electricity from nuclear reactors or water for drinking?

Large Fires and Explosions that Cause Loss of Coolant and Meltdown

On August 14th, the Intervenors filed seven more contentions regarding STP’s failure to comply with a new NRC fire safety rule which says each licensee must “develop and implement guidance and strategies intended to maintain or restore core cooling, containment, and spent fuel pool cooling capabilities under the circumstances associated with loss of large areas of the plant due to explosions or fire.” The NRC now requires nuclear plants to deal with explosions and fires that would occur from the impact of a large commercial airliner. STP claims that their submittal brings them in accordance with the new NRC rule. Intervenors and their expert argue the opposite in the contentions. However, the Intervenors’ contentions that argue STP has failed to meet the fire and explosion regulatory requirements, STP’s submittal, and related documents are considered classified by the NRC and are not available to the public.

The NRC has also recently adopted regulations that require all applicants for new reactor licenses, including STP, to complete “a design-specific assessment of the effects of the impact of a large, commercial aircraft.” After 9/11 the NRC did its own assessments of aircraft impacts using state-of-the-art techniques and “realistic predictions of accident progression and radiological consequences.” “This regulation recognizes that nuclear plants are vulnerable to air attacks with potentially catastrophic effects,” said Hadden. “Nuclear plants could become weapons if targeted by those who would do us harm.”
