Quad Cities Nuclear Power Station is composed of two Boiling Water Reactors and Steam Turbine/Generators located in Cordova, Illinois. Unit One has a Maximum Dependable Capacity of 855 MWe Net. The Station is jointly owned by Exelon Nuclear and MidAmerican Energy Company. The Nuclear Steam Supply Systems are General Electric Company Boiling Water Reactors. The Architect/Engineer was Sargent & Lundy, Incorported, and the primary construction contractor was United Engineers & Constructors. The Mississippi River is the condenser cooling water source. The plant is subject to license numbers DPR-29 and DPR-30, issued October 1, 1971, and March 21, 1972, respectively, pursuant to Docket Numbers 50-254 and 50-265. The dates of initial Reactor criticality for Units One and Two were October 18, 1971, and April 26, 1972, respectively. Commercial generation of power began on February 18, 1973, for Unit One and March 10, 1973, for Unit Two. [Ref: Introduction, Quad Cities Monthly Operating Report for May 2003]
NRC has a performance indicator and inspection finding matrix webpage for each plant. There are separate pages for Unit 1 and Unit 2
Quad Cities is located on the east bank of Pool 14 of the Mississippi River between Lock and Dams 13 and 14, and 815.1-km (506.5 mi) upstream from its confluence with the Ohio River, and about 32 km (20 mi) northeast of the Quad Cities Metropolitan Area of Davenport and Bettendorf, Iowa; and Rock Island, Moline, and East Moline, Illinois.
The current
operating licenses for both Units 1 and 2 expire on December 14, 2012. In
January 2003, Exelon applied to the NRC to renew these
for an additional 20 years of operation.

Quad Cities-1 - Steam Dryer Damage
On November 12, 2003, Quad Cities Unit 1 entered a forced outage to inspect and repair the units steam dryer. Thru-wall cracking was found in the upper dryer hood cover plate in the 270-degree azimuth of the dryer. The plate is a 1/2-inch thick cover plate welded in place with internal bracing, and the cracking is in the base metal of the plate. A piece of the plate, approximately 7 by 9 inches, cracked off and is currently missing. Inspections of the main steam lines have not indicated any evidence of the missing piece, and the licensee plans to check the annulus of the reactor for the missing piece next. Initial inspections inside the steam dryer also identified cracking and damage to internal support bracing. The licensee has assembled a team of Exelon, General Electric, and industry experts to assess the damage and develop repairs and corrective actions.

Operating Experience Related to Power Uprates:
Damage of Steam Dryer at Quad Cities Unit 2
In June 2002, approximately 3 months following implementation of a 17.8-percent EPU, Quad Cities Unit 2 experienced an increase in the moisture content of the steam provided by the reactor to drive the turbine. In July 2002, Exelon (the licensee for Quad Cities Unit 2) shut down the plant, identified cracking in the steam dryer as the cause of the increased moisture content, repaired the steam dryer, and returned the unit to power operation at the EPU power level. The steam dryer does not perform an accident-mitigating role or safety function, but is required to maintain its structural integrity. Approximately 10 months following restart of Quad Cities Unit 2 from an outage to repair the steam dryer, the plant experienced a similar increase in the moisture content of the steam. Based on previous experience with increased moisture content, Exelon shut down the plant and performed inspections of the steam dryer.
Upon inspecting the steam dryer, Exelon identified cracks in several locations of the steam dryer. In both cases, the licensee identified high-cycle fatigue as the cause of the cracking. The staff conducted a special inspection of Exelons activities related to the second incident.
The staffs inspection focused on Exelons efforts to identify the cause of the damage and repair the steam dryer. In addition, because Exelon had not completed its root-cause evaluation at the time of the inspection, it committed to keep Quad Cities Unit 2 at pre-EPU power levels until the root-cause evaluation is completed and presented to the NRC staff. On July 25, 2003, Exelon and General Electric Nuclear Energy (GENE) presented their determination of the cause of the cracking, repairs performed on the steam dryer, and planned actions to return the unit to the EPU power level. Following the July 25 meeting, the NRC staff held several additional discussions with Exelon and GENE regarding their analyses. Based on the understanding gained from the inspection, the July 25 meeting with Exelon and GENE, and the discussions following the meeting, the staff had no objections to Exelons plans to return the plant to the authorized EPU power level.
The staff has determined that the steam dryer failure at Quad Cities Unit 2 is not an immediate safety concern. Nevertheless, the staff has continued to monitor closely industrys generic response to this failure. GENE issued Services Information Letter (SIL) No. 644, BWR/3 Steam Dryer Failure, on August 21, 2002, to inform its customers of the first steam dryer failure and Supplement 1 to SIL No. 644, BWR Steam Dryer Integrity, on September 5, 2003, to inform its customers of the second steam dryer failure. Both of these documents provided recommendations for monitoring steam dryer performance to ensure that steam dryer degradation is promptly identified. The staff issued Information Notice (IN) 2002-026, Failure of Steam Dryer Cover Plate after a Recent Power Uprate, on September 11, 2002, to inform licensees of the first failure and Supplement 1 to IN 2002-026, Additional Failure of Steam Dryer after a Recent Power Uprate, on July 21, 2003, to inform licensees of the second failure. In addition, the staff has reviewed GENE SIL No. 644, Supplement 1, and provided comments on the technical evaluation and recommendations contained in the SIL. The staff is planning to meet with stakeholders in November 2003 regarding the SIL and industrys overall response to the experience with steam dryer cracking. The staff will consider its regulatory options based on industrys generic response.

Dresden and Quad-Cities will use Westinghouse fuel, the SVEA OPTIMA2 type, for sixteen refuelings, beginning with Quad-Cities-2 in 2006. This type of fuel is currently produced at Westinghouse-Sweden plant. The assemblies for the US contract will be made at the company's Columbia SC plant.
