NUCLEAR REGULATORY 

COMMISSION 

[Docket Nos. 50–280 and 50–281] 

Virginia Electric and Power Company; 

Notice of Consideration of Issuance of 

Amendment to Facility Operating 

License, Proposed No Significant 

Hazards Consideration Determination, 

and Opportunity for a Hearing 

The U.S. Nuclear Regulatory 

Commission (the Commission) is 

considering issuance of an amendment 

to Facility Operating License Nos. DPR–

32 and DPR–37, issued to the Virginia 

Electric and Power Company 

(Dominion, the licensee), for operation 

of the Surry Power Station, Unit Nos. 1 

and 2, located in Surry County, Virginia. 

The proposed amendment would 

allow use of an alternate methodology 

from that previously approved in 

Topical Report DOM–NAF–3–0.0–P–A, 

GOTHIC Methodology for Analyzing the 

Response to Postulated Pipe Ruptures 

Inside Containment, as discussed in the 

Surry Power Station, Unit Nos. 1 and 2, 

Updated Final Safety Analysis Report 

(UFSAR). The approved methodology 

was used to establish boundary 

conditions (i.e., pressure, liquid 

temperature and water level) for the 

Surry recirculation spray (RS) strainers 

being installed in the Surry Units 1 and 

2 containment buildings. The boundary 

conditions are required to assess the RS 

strainer internal hydraulic performance 

following a loss-of-coolant accident 

(LOCA). The NRC-approved 

methodology contains significant 

conservatisms, which are included in 

the GOTHIC net positive suction head 

(NPSH) available models to maximize 

liquid temperatures and minimize 

containment pressure for design-basis 

containment response evaluations. 

However, these conservatisms are 

creating bulk conditions that are too 

conservative for application to the sump 

strainer performance. Specifically, for 

certain LOCA analyses, the overly 

conservative conditions result in a 

prediction of two-phase flow in the RS 

strainer for a short period of time. 

Therefore, an alternate containment 

GOTHIC analysis methodology is 

proposed to reduce certain overly 

conservative assumptions to more 

realistically, yet conservatively, address 

expected plant conditions in 

containment following a LOCA. The 

alternate method relaxes some of the 

conservatisms in the NPSH analysis 

methodology in Topical Report DOM–

NAF–3.0–0–P–A. The proposed 

alternate methodology will be used to 

demonstrate that the RS pumps have 

adequate NPSH available throughout 

their required service time. 

The licensee had performed 

calculations following an NRC audit at 

the licensee’s North Anna Power Station 

during the week of July 16, 2007, where 

an NRC auditor requested 

documentation of the subcooling margin 

inside of the containment sump 

strainers. During review of the 

calculations, it was identified that 

dynamic head change in the strainer 

had not been included in the 

calculation. Following a new 

calculation by the strainer vendor, 

which showed that flashing would not 

occur at North Anna, a new Surry 

calculation was performed which 

showed that flashing would occur under 

certain conditions that would result in 

the RS pumps having inadequate NPSH 

when four RS pumps were in operation 

at the same time. The approved GOTHIC 

containment analysis methodology for 

deriving NPSH was reviewed to 

determine whether the predicted 

flashing was reasonable. After several 

weeks of reviewing the GOTHIC model 

and its associated conservative inputs 

and assumptions, it was concluded that 

an alternate GOTHIC methodology was 

required to demonstrate that flashing 

would not occur. The proposed 

alternate methodology allows for a 

larger liquid-vapor interface area that 

accounts for additional heat transfer 

between the containment vapor and the 

liquid phase which is not credited in 

the existing methodology. The 10 CFR 

50.59 review completed for the design 

change package for installation of the 

Unit 1 sump strainer during the current 

refueling outage indicated that NRC 

approval would be required before the 

strainer was declared operable and 

before the Surry Unit 1 startup could 

commence following the refueling. The 

corresponding operability of the 

partially installed Surry Unit 2 strainer 

was addressed in accordance with the 

licensee’s operability determination 

process. These determinations were 

completed and discussed with NRC staff 

on October 16, 2007. Consequently, the 

specific need for the Surry specific 

GOTHIC containment analysis
