I REACTIVITY CONTROL SYSTEMS BASES 3/4.1.2 BORATION SYSTEMS (Continued)
With the RCS temperature below 200*F, one injection system is acceptable without single failure consideration on the basis of the stable reactivity condition of the reactor and the additional restrictions prohibiting CORE ALTERATIONS and positive reactivity change in the event the single injection system becomes inoperable.
The baron capability required below 200*F is sufficient to provide a SHUTDOWN MARGIN of 1% ak/k after xenon decay and cooldown from 200*F to 140*F. This condition requires either 835 usable gallons of 7000 ppm borated water from the boric acid storage tanks or 9690 usable gallons of 2000 ppm borated water from the refueling water storage tank.
Tne required boric acid storage tank volume of 835 gallons is below the usable level instrumentation range and thus has been increased to a value on scale (5000 gallons). The required RWST volume of 9690 gallons must be increased to account for nonusable volume due to tank geometry and vortexing considerations (87,690 gallons).
3/4.1.3 MOVABLE CONTROL ASSEMBLIES
.The specifications of this section ensure that (1) acceptable power distribution limits are maintained, (2) the minimum SHUTDOWN MARGIN is maintained, and (3) limit the potential effects of a rod ejection accident.
OPERABILITY of the control rod position indicators is required to determine control rod positions and thereby ensure compliance with the control rod alignment and insertion limits.
The ACTION statements which permit limited variations from the basic requirements are accompanied by additional restrictions which ensure that the original criteria are met. Misalignment of a rod requires measure-ment of peaking factors or a restriction of THERMAL POWER; either of these restrictions provide assurance of fuel rod integrity during continued operation. The reactivity worth of a misaligned rod is limited for the remainder of the fuel cycle to prevent exceeding the assumptions used in the accident analysis for a rod ejection accident.
The maximum rod drop time restriction is consistent with the assumed rod drop time used in the accident analyses. Measurement with Tavg 1 550*F ard with all reactor coolant pumps operating ensure that the measured drop times will be rep.esentative of insertion times experienced during a reactor trip at operating conditions.
1664 310 TROJAN-UNIT 1 B 3/4 1-3
REACTIVITY CONTROL SYSTEMS BASES 3/4.1.3 MOVABLE CONTROL ASSEMBLIES (Continued)
Control rod positions and OPERABILITY of the rod position indicators are required to be verified on a nominal basis of once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> with more frequent verifications required if an automatic monitoring channel is inoperable. These verification frequencies are acequate for assuring that the applicable LC0's are satisfiea.
The restriction prohibiting part length rod insertion ensures that aaverse power shapes and rapid local power changes which may effect DNB considerations do not occur as a result of part length rod insertion during operation.
