(i 214. Nuclear Instrumentation System 215 Radiation Monitoring System 218 Fuel Handling System 224 Compressed Air Systems 231 Vapor Containment 232 Radiation Shielding 235 Architectural Features Physical arrangements of structures and equipment will be as described in Section 200 of the license application.
Mechanical equipment and systems will be interconnected as shown in the Fundamental Flow Diagram included in that section.
Elcetrical equipment and systems which provide station auxiliary power supply will be as described in Section 226 of the license application and will be interconnected as shown in the 2400 volt one-line diagram and the 480 volt one-line diagram, sheets 1, 2 and 3, included in that section.'
The ventilation system for the control room area, radiochordcal laboratory, decontamination cubicle, fuel transfer pit house, and other potentially contaminated portions of the Turbine Cencrator Service, Primary Auxiliary, and k'aste Disposal Buildings shall be in accordance with tne description contained in Section 228 of Part B of the license application.
3.
The Performance Analysis for the current reload core, " Yankee Nuclear Power Station Core XII Performance Analysis, July 9, 1975" (as supple-mented October 10, 1975, and February 19, 1976), and the "Additi6nal LOCA Analysis - Appendix B" dated. February 20, 1976, are incorportted as part of these technical specific'ations. The analysis presented in the FSAR for Core XI forms the basis for the reference core performance analysis.
C.
PERFORRCCE SPECIFICATIONS Calculated values of operating variables such as pressures, temperatures, floss, heat fluxes, reactivity coefficients and on-site radiation levels under steady state and transient conditions which are stated in the sections of the license application listed in Paragraph B, above, are considered to be performance specifications of the reactor and are incorporated by reference herein.
Yankee shall not operate the facility under circumstances-where there is a substantial vcriance between the foregoing performance specifications and the corresponding values determined by operation of the facility.
The performance and function of the systeta described in the following sections of the license application shall be substantially as described; however, the details of individual components and their arrangement as described in each of these sections may be altered by Yankee et its own discretion. previded that such an alteration would not violate some other provision of these Technical Specifications:
Amendment No. 26

Yanhec P.cwe is stable with, respect to xenon, a.nd any r.cnon trcnsier.ts which may be, excited are rapidly damped.
The' xenon multiplier in rigure*8-4 vas selected to conservatively account for transients which can result i
from control; rod motion at full power.
The 11 nits on power Icyc1 and control red position follo. ting centrol r M incertion were selected to prevent
' exceeding the maxime.m allevabic linear heat generatica rate lir.its in Tigurc 8-1 within the first few hours following return to pcwcr after the insertien..With Yard.ce's highly der. ped core, the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> hold alices I
suf ficient tire for the initial. xenen maldistributien to acce nodate itself to the new power distributien.
The rcstriction on centrol red locatica during these twenty four hours assures that the return to allowc.bic fractica of full pcwer will not cause additional redistributica--
j due to rod motion.
.1 These conclusions are based on plant tests and on calculations nerforced with the SDTJIML threce dimensional n'odal code used in the onnlysis of Core XI
