SUBJECT:
REQUESTS FOR ADDITIONAL INFORMATION FOR THE REVIEW OF THE SUSQUEHANNA STEAM ELECTRIC STATION, UNITS 1 AND 2, LICENSE RENEWAL APPLICATION
Dear Mr. McKinney:
By letter dated September 13, 2006, PPL Susquehanna, LLC submitted an application pursuant to 10 CFR Part 54, to renew the operating licenses for Susquehanna Steam Electric Station, Units 1 and 2, for review by the U.S. Nuclear Regulatory Commission (NRC or the staff). The staff is reviewing the information contained in the license renewal application and has identified, in the enclosure, areas where additional information is needed to complete the review.
These requests for additional information were discussed with Duane Filchner, and a mutually agreeable date for the response is within 30 days from the date of this letter. If you have any questions, please contact me at 301-415-1594 or e-mail yks@nrc.gov.
Sincerely,
/RA/

RAI 2.3.3.13-1 LRA drawing LR-M-122, Sheet No. 1, Fire Pumphouse, North & South Gatehouse & Security Control Center Buildings, shows the jockey pump and associated components as out of scope (i.e., not colored in green). Section 9.5.1.1 of the Susquehanna Steam Electric Station (SSES), Units 1 and 2 Safety Evaluation Report (SER) (NUREG-0776), dated April 1981, states that a separate jockey pump automatically maintains the yard fire main pressure. The jockey pump and its associated components appear to have fire protection intended functions required for compliance with 10 CFR 50.48 as stated in 10 CFR 54.4. The staff requests that the applicant verify whether jockey pump and its associated components are in the scope of license renewal in accordance with 10 CFR 54.4(a) and subject to an Aging Management Review (AMR) in accordance with 10 CFR 54.21(a)(1). If they are excluded from the scope of license renewal and not subject to an AMR, the staff requests that the applicant provide justification for the exclusion.
RAI 2.3.3.13-2 The following LRA drawings show fire protection system components as out of scope (i.e., not colored in green):
LR-M-122 Sheet 1, Fire Pumphouse, North & South Gatehouse & Security Control Center Buildings, shows Diesel Oil Day Tank (0T508) vent line and the fill cap-assembly line, piping, fittings, and drains as out of scope (i.e., not colored in green).
LR-M-122 Sheet 2, Turbine Bldg., Control Structure and Radwaste Building, shows several fire suppression systems and components in Turbine Building Units 1 and 2 as out of scope (i.e., not colored in green).
LR-M-122 Sheet 3, Reactor Bldg., Standby D G, River Intake Structure., Service and Admin.
Bldg. & Circ. Water Pumphouse, shows several fire suppression systems and components in Turbine Building Units 1 and 2, Circ. Water Pumphouse, and River Intake Structure as out of scope (i.e., not colored in green).
LR-M-122 Sheet 4, Carbon Dioxide System, shows several components as out of scope (i.e.,
not colored in green).
The staff requests that the applicant verify whether the above fire suppression systems and components are in the scope of license renewal in accordance with 10 CFR 54.4(a) and subject to an AMR in accordance with 10 CFR 54.21(a)(1). If these components are excluded from the scope of license renewal and not subject to an AMR, the staff requests that the applicant provide justification for the exclusion.
RAI 2.3.3.13-3 Section 9.5.1.2 of the SSES SER (NUREG-0776), dated April 1981, listed sprinkler and standpipe systems provided in the plant areas for fire suppression activities. The sprinkler and standpipe systems are installed in various areas:
! Reactor Core Isolation Cooling Pump Room
! High Pressure Coolant Injection Pump Room
! Heating, Ventilation, and Air-Conditioning Filter Rooms
! Railroad Airlock
! Control Building Auxiliary Rooms
! Condenser Area
! Reactor Feed Pump Turbine
! Turbine Central Area
! Turbine Condenser Gallery
! Turbine Hydro Control Power Room
! North Railroad Bay
! Turbine Condenser Mezzanine
! Diesel Engine Fire Pump Room
! Lower Cable Spreading Room (CSR)
! Upper CSR
! PFP Turbine Room
! Diesel Generator Building
! Charcoal Filters
! Standby Gas Treatment Filters
! Emergency Outside Air Filters
! Centrifuge & Conditioner
! Turbine Pump Area
! Turbine Hydro Seal Oil Unit
! Turbine Lube Oil Area
! Turbine Motor Generator Area
! Turbine Filter Room
! Turbine Moisture Separation Area
! Radwaste Tank Vent Filter Room
! Radwaste Auxiliary Rooms
! Radwaste Controlled Zone Shop The staff requests that the applicant verify whether the sprinkler and standpipe systems installed in the above areas of the plant are in the scope of license renewal in accordance with 10 CFR 54.4(a) and subject to an AMR in accordance with 10 CFR 54.21(a)(1). If they are excluded from the scope of license renewal and not subject to an AMR, the staff requests that the applicant provide justification for the exclusion.
RAI 2.3.3.13-4 Section 9.5.1.3 of the Susquehanna Steam Electric Station SER (NUREG-0776), dated April 1981, discusses the low pressure carbon dioxide (CO2) fire suppression systems for electrical equipment rooms, generator purging, concealed floor and ceiling spaces.
This section also discusses self-contained Halon 1301 fire extinguishing systems for power generation complex modules.
The total flooding CO2 fire suppression systems for electrical equipment rooms, generator purging, concealed floor and ceiling spaces and self-contained Halon 1301 fire extinguishing systems for power generation complex modules do not appear in LRA Section 2.3.3.13 as being in the scope of the license renewal and subject to an AMR. The staff requests that the applicant verify whether the CO2 fire suppression systems for electrical equipment rooms, generator purging, concealed floor and ceiling spaces and Halon 1301 fire extinguishing systems for power generation complex modules are in the scope of license renewal in accordance with 10 CFR 54.4(a) and subject to an AMR in accordance with 10 CFR 54.21(a)(1). If they are excluded from the scope of license renewal and not subject to an AMR, the staff requests that the applicant provide justification for the exclusion.
RAI 2.3.3.13-5 LRA Table 2.3.3-13 excludes several types of fire protection components that appear in the Susquehanna Steam Electric Station SER (NUREG-0776), dated April 1981 and/or Fire Protection Review Report. These components are listed below:
! Hose stations
! Spray nozzles (water, CO2/Halon)
! Dikes for oil spill confinement
! Floor drains and curbs for fire-fighting water
! Filter housing
! Strainer housing
! Heater housing
! Chamber housing
! Actuator housing
! Pipe supports
! Halon storage bottles
! Water storage tanks
! Buried outside diesel fuel storage tanks
! Heat exchanger (bonnet)
! Lubricating oil collecting system components (reactor coolant pump)
! Engine intake and exhaust silencers/muffler (diesel driven fire pump)
! Manual smoke removal systems and their associated components (control structure including CSRs)
The staff requests that the applicant verify whether the components listed above should be included in LRA Table 2.3.3.13. If they are excluded from the scope of license renewal and not subject to an AMR, the staff requests that the applicant provide justification for the exclusion.
RAI 2.3.3.13-6 LRA Section 2.3.3.13 discusses requirements for the fire water supply system but does not mention trash racks and traveling screens for the fire pump suction water supply. Trash racks and traveling screens are located upstream of the fire pump suctions to remove any major debris from the fresh or raw water. Trash racks and traveling screens are necessary to remove debris from and prevent clogging of the fire protection water supply system. Trash racks and traveling screens are typically considered to be passive, long-lived components. Both trash racks are and traveling screens are located in a fresh or raw water/air environment and are typically constructed of carbon steel. Carbon steel in a fresh or raw water environment or water/air environment is subject to loss of material, pitting, crevice formation, and microbiologically influenced corrosion, and fouling. Explain the apparent exclusion of the trash racks and traveling screens that are located upstream of the fire pump suctions from the scope of license renewal in accordance with 10 CFR 54.4(a) and subject to an AMR in accordance with 10 CFR 54.21(a)(1).
