7. Traversing In-Core Probe Sys~em (References 4 and 12) 7.1. Description

-When the traversing in-core probe Cf IP) syster:n (fdr the required niea~urem~nt locations) .is used for recalibration* of the* LPRM detectors and monitoring thermal limits, the TIP system shall be operable wlt_hfae foliowing: *

1. movable_ detectors, drives, .~nd reac;lout equipment to map the core in the required mec1surement locations, ahd y ' - ' ' ' .-.* '
2. indexing equipmenfto afiow all required dete_C::t!'.)rS ,to be Cc:iliQr?t~c:f in .9 common location.

The followin~ applies for use with 3DM:

  • At any time, including BOC, th~ total numb.er of faile:!d afia/or bypassed LPRMs does not exceed 25%.. In addition, . nb more than .14

., ' '~. ,, JIP can channels . . bef00$ (failed or rejected) (Reference 4). .} - " ' '.'-. Otherwise, with the TiP system-inoperable, suspend use c:ifth~ system for the above applicable calibration functions. . . ' ' 7 .2. Bases <:

  • The operability of the TIP system with the _above specified minimum cornplement of equipment ensures that the measurements obtained from use of this equipment accurately represent the spatial neutron flux: distribution of the reactor c6re .. The normalization of the required detectors is performed internal to the core monitoring software system. .

The one TCV i;ind/or TSV OOS conditions require power level :;; 85% of rated. The one MSIVOOS condition is also supported if thermal power is maintained :;; 75% of rated (Reference 7). (2) The 2 TBVOOS in the Base Case are not credited for fast opening or opening on pressure control (Reference 6). The assumption is that two TBVs do not open on any signal and thus remain shut for the transients analyzed (i.e. 3 TBVs are credited to open in pressure control) (Reference 9). (3) For Application Conditions involving 5 TBVOOS, the 5 TBVs are NOT credited for fast opening and 3 TBVs will not open on pressure control (Reference 6). The #5 TBV is not available for pressure relief and thus cannot be used as one of the credited valves to open in pressure control. (4) The + sign that is used in the Equipment Out of Service Option / Application Group descriptions designates an "and/or" (Reference 6). * (5) All EOOS Options are applicable to the entire range of licensed flow and feedwater temperature (MELLLA, ICF, FFWTR, and coastdown) unless otherwise specified (Reference 7). SLO is not applicable to MELLLA or ICF. (6) All EOOS options in Table 9-1 can be used with Option A or B MCPR limits (Reference 7).
