9 Format The format of the Updated FSAR ls consistent with the original FSAR with the following exceptions:
The original FSAR contained two volumes of Requests for Additional Information (RAls) and their subsequent responses.
The RAls were the result of the Commission's questions pertaining to New Hampshire Yankee's (NilY) application for an Operating License, -Information from the RAls has been incorporated into the Updated FSAR, as applicable, and thus is no longer - needed as a stand alone document.
Additionally, certain Appendices, identified by asterisks on the UFSAR Effective Page Listing were not revised, and are provided in the Updated FSAR for historical information.
Generic Chances Apolicable to All Chanters The following generic changes are applicable to all chapters of the Updated FSAR (UFSAR):
References to Unit 2, have been climinated wherever possible. Unit 2 was cancelled in 1984. The Unit 2 construction permit was allowed to expire in October 1988. It was necessa_ry to retain Unit 2 references in certain places that involved descriptions or calculations based on both units, e.g., the Exclusion Area boundary is defined as the 3000 foot radius around the Unit I and Unit 2 centerlines, and calculations such as in Tables 12.21 through 12.2 37.
Editorial revisions reflect the completion of plant construction activities and the commencement of plant operations. Terminology and typographical errors have also been corrected.
Maior Revisions by Chanter Chapter 1 Section 1.2.2, Facility Arrangement Revisions to General Arrangement (GA) Drawings. The G A drawings are included in the FSAR as Figures 1.21 through 1.2 59.
Change documents affecting the GA drawings have been tracked in the Controlled Document Tracking (CDT) System. NHY incorporated all outstanding revisions to GA drawings for this UFSAR submittal.
Section 1.3, Comparison Tables to Similar Facilities and Design Changes Since PS AR.
NRC guidance for Updated FSARs indicates that this section need not be updated. A-note has been added to this section stating that the tables have lOI
not been updated for the UFSAR, but are included for consistency with the FSAR.
Section 1,7, Drawings and Other Detailed Information The FSAR contained a listing of design drawings, including their revision numisers and date. Because NHY is regularly updating some categories of design drawings, this FSAR listing was not a reliable source for drawing status information and has been deleted. A brief description has been added to Section 1.7 explaining the NHY drawing program.

Section 2.2.2.5(b), Pease Air Force Base Description This section has been revised to update the status of the base in response to its closure in accordance with the Base Closure and Realignment Act.
Information provided in this section provides the basis for containment design and other Seabrook Station design criteria and has been retained in its entirety.
The air traffic pattern at Pease is projected to be limited to the New
- Hampshire Air National Guard and will be significantly reduced from previous activity.
Section 2.3.3.3, Meteorological Monitoring System A description of the Backup Meteorological Monitoring System was added.
The system desc ription identifies locations, capability of its monitoring equipment, and power source independence from the Primary Meteorological Monitoring System, Chapter 3 Section 3.7(B).4.2, Seismic Instrumentation Triaxial Response Spectrum Recorder XR6708 was relocated from the Service Water Pumphouse (SWPH) foundation south corner to the SWPil electrical room, west wall, north of column 12, elevation 22' 0".
3.8.2.1,(f), Description of the Containment Penetrations The description of the fuel transfer tube assembly was revised to identify the design and fabrication codes for the new " quick closure" fuel transfer tube -
hatch, located on _the refueling canal side.
This change' also corrects the O
ASME code class and subsection upplicalile to the fuel transfer tube and its fla nge s.

i Gi Chanter 4 Section 4.3.2.6, Criticality of the Reactor During Refueling and Criticality of the Fuel Assemblics The FSAR was revised to correctly refer to the YAEC discussion of criticality of the reactor during refueling and criticality of fuel assemblies in U FS A R, Section 9.1.
The Westinghouse discussion is deleted.
Chapter 5 5.2.5.3, Leakage Detection Methods Reference was added to installation of a containment gaseous radiation backup monitor, which will act as a backup to the regular monitors. The backup monitor, along with containment sump level channel, will provide a minimum of two out of three channels required by the Technical Specifications.
Figure 5.1-1, Reactor Coolant System
\\J Drawings were updated to show re fe rcince leg connections for mid loop y
operation level transmitters and new residual heat ternoval pump suction pressure transmitters. Instrumentation enhancements are per Generic Letter 8817, " Loss of Decay llent Removal."
ChapteJJ Table 6.2-92, Containment Liner Penetrations This table is revised to add penetrations X 77 and X 78 as " essential" penetrations. These penetrations are the RVLIS tubing penetrations used for RCS wide range pressure and for the RVLIS function for post-accident monitoring.
Section 6.3.5.3, Emergency Core Cooling System Flow Indications The FSAR contained a description of Residual Heat Rernoval(RHR) pump hot leg injection flow instrumentation.

include RHR pump hot leg injection / recirculation flow instrumentation. Table 6.3 5 is also revised as a result of this change.
Section 6.4.2.2, Habitability Systems The smoke monitoring instrumentation system is revised to identify that it is not powered or controlled from the emergency electrical distribution and is not
- ensured of power during all modes of operation as stated in the FSAR.
Section 6.6.6, In Service luspection Examination Results This section is revised to update the references to the ASME Code sections and w reflect the current status of the In Service Inspection (ISI) Program.
Chapter 7 Section 7.1.2.5, Conformance of Regulatory Guide and Section 7.3.2.2 These sections were revised to identify additional equipment that should not be tested at power so as not to damage plant equipment.
-Table 7.51, Accident Monitoring Instruction List Temperature elements for indicating the area temperature in Battery Rooms A&B were added and these elements are listed on Table 7.51.
Section 7A.12, ATWS Mitigation System A new section, 7.6.12 describes the ATWS Mitigation System. Figures were
- updated to support the new description.

_.O; Section 8.2, Offsite Power Systems This revision reflects the installation of the Tewksbury line. The text referred to the installation of two lines prior to startup of Unit I with the third line installed prior _ to startup of Unit 2.
All three lines were installed prior to Unit 1 operation.
Therefore, the text was revised to show the actual configuration and descriptions. The forced outage rates and grid availability data are being revised to reflect the current data. The 1989 data and analysis conclude ~ that the availability factors have improved.
Section 8.2.1.5, Compliance with General Design Criterion 17 and NRC Regulatory Guide 1.32 This description was modified to clarify the two independent circuit paths as required by GDC 17. This change is required to clearly define the different connections that can be made between the UATs and the RATS to the onsite distribution system to meet the regulatory intent. This revision does not alter the original design intent and is supported by the existing Technical Specifications.
Tables 8.3 1 & 83-2, Diesel Generator Loading Sequence The diesel generator tables were revised to account for replacing'the existing nonsafety-related single phase Uninterruptable Power Supply (UPS) 14 with 4
a three phase UPS.
Chanter 9 Tables 9.1 1, 9.2 4, and 9.2 5, Spent Puel Pool These tables were upda_ted to provide revised design information on spent fuel pool heat loading according to the current design calculations.
Section 9.3.3, Equipment and Floor Drainage System Based on a review of the Station Chemistry Manual, the FSAR was updated '
to reflect present policy not to use chromates in the plant, because chromates are categorized as hazardous waste.

9.3.1.2, Plant Compressed Air Subsystem A discussion of the plant compressed air centrifugal compressor is added to the permanent plant design has been incorporated into this section.
9.5.1, Fire Protection System The Fire Protection Systeta description was corrected to identify that there are two (one functioning as a spare) 1500 gpm diesel engine-driven centrifugal fire pumps. This correction provides conformance with actual plant design.
Section 9.3.6, Equipment Vent System The hydrogenated vent header system description has been revised to indicate that gas from the letdown degasifier and the primary drain tank degasifier is collected.
Table 9.5 9, Listing of Unusually Hazardous Materials The table was updated to include the sodium hypochlorite storage tanks in the chlorination building on the hazardous material storage listing. This table was also-updated to reflect the current onsite gas inventory evaluation as documented by SBP 90 031.
O Chanter 10 Section 10.2.2, Automatic Controls for Turbine Trip This section was revised to incorporate an interlock to the main generator breaker trip, so_ that a manual control switch trip of the breaker causes an immediate trip of the turbine.
Section 10.4.4, Steam Dump System Valve stroke time for steam. dump valves was modified from three to five seconds for operation of full closed to full-open. This change was the result of modifications to the valves stem / bushing hardness to eliminate galling.
Section 10.4.5, Circulatory Water System This section' was modified to include two ' additional hypochlorite storage tanks -
for-chlorination when the generating cells are secured.

Chapter 11 Section-11.3, Radioactive Gaseous Waste System This section states that hydrogen concentration is monitored in _ cubicles containing RGWS components to detect a leak in the system. Statements have been added to clarify that monitoring is not required when the RGWS is inerted with nitrogen. This situation is acceptable since there is no potential for an explosive mixture forming in the cubicles from RGWS leakage when the system is inerted with nitrogen.
Section 11.4, Solid Waste Management System This section was revised to document the fact that an asphalt wasteform qualification program has been completed and the results accepted by the NRC.
Section 11.5, Process and Effluent Radiological Monitoring and Sampling System This section has had numerous updates as a result of a Design Basis Document (DHD) review. Minor revisions were made throughout, including Table 11.5 1.
- Chapter 12 Section 12.1.2.3, Reduction of Radiological Conditions Subsection -k was revised to reflect that the-Key Card Entry System is supplemented by barricading and/or locking to control access.
'Section 12.2, Radiation Sources
- A paragraph was added to identify which tables (Tables 12.2-1 through 12.2-37) represent information for I-or 2 Unit operation.
These tables were not revised but may be the subject for reanalysis in the future.
Section 12.3.4, Area Radiation and Airborne Radioactivity Monitoring Instrumentation-E The discussion of the spectral correctional monitor was deleted since it is no longer used.- A pontable air pump and ionization chamber detector is now used i-as the WRGM backup.
