l: 1 CHANGE NUMBER ElfC DESCRIPTION plant shutdown to Mode 3 requirement would be required in one less hour. 13 05 A This proposed change would involve retaining an action statement, currently in the plant TS, that permits continued POWER OPERATION with more than one digital rod position indicator per group inoperable. This is in accordance with the current licensing basis of the plant. 13 06 A Consistent with NUREG 1431 Rev. 1, a separate condition entry allowance is permitted in current TS 3.1.3.2 for each inoperable rod position indicator and each demand position indicator. This is an administrative change since the Required Actions address each rod or bank with inoperable indication separately [and Action b addresses the condition of multiple inoperable DRPIs, up to a complete loss of digital position indication]. 13 07 M The proposed modifications to the SR would require a verification of agreement between digital and demand indicator systems prior to criticality after each removal of the reactor vessel head, instead of every 12 hours. This reflects a reorganization of surveillance requirements in the ITS. The requirement for a 12 hour comparison would be moved to SR 3.1.4.1 in the ITS. The post vessel head removal requirement would be a new specification that demonstrates rod position system OPERABILITY based on a comparison of indicating systems. The Frequency requirement of prior to criticality after i each removal of the reactor vessel head would permit this  ! comparison to be performed only during plant outages that involve plant evolutions (vessel head removal) that could affect the OPERABILITY of the rod position indication systems. The Frequency change is based on traveler TSTF 89. 13-08 LS 20 Not applicable to Callaway.

Multiple inoperable               l DRPls, of themselves, ave no impact on SDM in MO              1 and 2 if the control rod positions are verified by ernate means (e.g., movabHfincore detectors). The requirement to place contr rods in manual may (be appropriate in all situations and may be detrimentalfor load r etion transient niess operator action is assumed to simulate the rod control system automati . Accidents analyzed using the[ Improved Thermal Design Procedure (ITDP) ss e that the control rods are in [ automatic).

Automatic rod movement can acco odate a 10% load rejection. Placing rods in manual may impact the load rejec ' n pability assumed when the P-9 setpoint was established at 50% RTP, The s am du system can accommodate a 40% RTP load rejection and with the rod co rol system i utomatic, a 50% RTP load rejection can be accommodated without a actor trip. While anual operator action can be just as timely as automatic rod contr , there is no need to h e this limitation in the Technical Specifications. Corr ive actions for excessive d motion are covered under ITS 3.1.7 Condition C. The equirement to monitor end reco T,y hourly is unnecessary given the available indi ors and alarms, e.g., T,y - Tn,e devia ' n alarm, to alert operators to changing m erator conditions. 4 Nrf tued. & 2.l-19

FETE & 3,/-l9 IV. SPECIFIC N0 SlGNIFICANT HAZARDS CONSIDERATIONS NSHC LS 23 1 10 CFR 50.92 EVALUATION  ! FOR l TECHNICAL CHANGES THAT IMPOSE LESS RES CTIVE RE0VIREMENTS WIT 111N THE TECHNICAL SPEC ICATIONS The proposed hange would delete the Actions to pla control rods in manual and record RCS T., hourly if multiple DRPIs per group e inoperable. Actions b.1.b) and b.1.c) of LC0 3 1.3.2. Multiple inoperable DRPI will have no impact on SDH in Modes 1 and 2 if he control rod positions are erified by alternate means (e.g., movable incore de ctors). The requirement t place control rods in manual is not appropriate in all ituations and may be de imental for load rejection transients unless operator acti n is assumed to simul te the rod control system in automatic. Accidents analyzed us'ng the [ Improved T rmal Design Procedure (ITDP)] assume that

                                                                                                  )

I control rods are in [a tomatic]. Aut tic rod movement can accommodate a 10% load rejection. The requir nt to monito and record T., hourly is unnecessary given the I available indicators and larms, e.g , T,, Tm deviation alarm, to alert operators to changing moderator con tions. This proposed TS change has n evaluated and it has been determined that it i involves no significant hazar consideration. This determination has been i performed in accordance with criteria set forth in 10 CFR 50.92(c) as quoted i below: l "The Corrmission ma make a 'nal determination pursuant to the procedures in 50.91. that a pro osed amen nt to an operating license for a facility licensed under 5 .21(b) or 50. or for a testing facility involves no significaat ha ros considerati . if operation of the facility in accordance with the prop ed amendnent woul ot:

1. Invol e a significant increas in the probabi1ity or consequences of an acc ' dent previously evaluated; r
2. C eate the possibility of a new o different kind of accident frorn any ccident previously evaluated; or

The foll ing evaluation is provided for the three cate ries of the significant hazards consideration standards:

1. Does the change involve a significant increase the probability or consequences of an accident previously evaluated?

Overall protection system performance will remain within th bounds of the previously performed accident analyses since no hardware chan es are proposed. The reactivity transients analyzed in FSAR Section 15.4 will b unaffected N0 SIGNIFICANT HAZARDS CONSIDERATION 50 5/15/97

The pr sed change will not affect the probabilit of any event initiators nor will the proposed change affect the ability any safety related equipment o perform its intended function. T re will be no degradation in the perfo nce of nor an increase in the n r of challenges imposed on safety relat equipment assumed to functi during an accident situation. Therefore, the roposed change does not i volve a significant increase in the probability or nsequences of an accid t previously evaluated.

2. Does the ch ge create the po bility of a new or different kind of accident from ny accident eviously evaluated?

There are no hardware anges r are there any changes in the method by which any safety-related plan syst performs its safety function. This change will not affect the norma hod of plant operation. No new accident scenarios, transient precu ors, failure mechanisms, or limiting single failures are introduced a a esult of this change. Therefore, the proposed change does not create pos ibility of a new or different kind of accident from any previously ev uated.

3.1-8 The Frequency for ITS SR 3.1.7.1 for comparing DRPI and group demand I position would be changed from 18 Months to "Once prior to criticality after each removal of the reactor vessel head." This change makes it clear that the surveillance must be performed each time the head is removed and that it is not tied to an absolute time interval. This change is based on traveler TSTF 89. 3.1 9 This change would eliminate ISTS 3.1.2 because the SDM requirements for MODE 5 have been incorporated into Specification 3.1.1 in accordance with traveler TSTF 136. Traveler TSTF 9. L.1. relocated values for7R'-3./-ogg SDM to the COLR which removed the only difference between ISTS LC0 3.1.1 and ISTS LCO 3.1.2. Differences above and below 200*F will be addressed in the COLR. Subsequent sections have been re numbered. 3.1 10 Several surveillances (e.g. rod position deviation monitor and rod insertion limit monitor in this section) contain actions in the form of increased surveillance frequency to be performed in the event of inoperable alarms. These actions are moved from the TS to licensee controlled documents since the alarms do not themselves directly relate , to the limits. This detail is not required to be in the TS to provide ' l' adequate protection of the public health and safety.

In summary this change is acceptable because it would permit time to perform required flux mapping, permit orderly resetting of the high flux trip setpoints, and reduce the chances of an inadvertent reactor trip during the required power reduction. 3.2 07 Consistent with TSTF 97, the NOTE in SR 3.2.1.2 is revised by removing the phrase "is within limits and" to clarify that the actions to be t taken if F (Z)e is increasing are required regardless of whether F a(Z) is within its limits. 3.2 08 Consistent with TSTF 99, the LC0 3.2.1 (F aMethodology).

Q 3.2-3/Q 3.2-7 INSERT 3.2-12 3.2-12 The required time for completion of a flux map for determination of the heat flux hot channel factor is changed from 12 hours to 24 hours after achieving equilibrium conditions. The proposed change affects SR 3.2.1.1 and SR 3.2.1.2. A flux map is taken after a power level increase greater than a specified amount to verify FQ is within limits and to provide assurance that FQ will remain within limits until the next required flux map is taken. Based on plant experience, the flux maps taken during power ascension provide a high degree of confidence that FQ will be within limits at the next power plateau. As such, the exact time period allowed for performance of the surveillance, after reaching equilibrium, is not a significant safety consideration. The proposed time (24 hours)is a reasonable time period for obtaining and evaluating a flux map and then completing the procedural steps associated with this surveillance. Further, the 24 hour time period provides a reasonable limit on the length of time that the plant can operate in an unconfirmed condition. 1 l

(continued) LCO The LCO establishes the minimum conditions required to ensure that the accumulators are available to accomplish their core cooling safety function following a LOCA. Four accumulators are required to ensure that 100% of the contents of three of the accumulators will reach the core during a LOCA. This is consistent with the assumption that the contents of one accumulator spill through the break. If less than three accumulators are injected during the blowdown phase of a LOCA. the ECCS acceptance criteria of 10 CFR 50.46 (Ref.p could be violated. c) eg_,7, gag j For an accumulator to be considered OPERABLE, the isolation valve must be fully open, power removed above 2000 [0_00 psig, and the limits established in the SRs for contained volume, boron concentration, and nitrogen cover pressure must be met. APPLICABILITY In MODES 1 and 2, and in MODE 3 with RCS pressure > 1000 psig, the accumulator OPERABILITY requirements are based on full power operation. Although cooling requirements decrease as power decreases, the accumulators are still required to provide core cooling as long as elevated RCS pressures and temperatures exist. This LC0 is only applicable at Bg pressures > 1000 psig. At pressures s 1000 psig, the rate of RCS blowdown is such that the i ECCS pumps can provide adequate injection to ensure that peak . clad temperature remains below the 10 CFR 50.46 (Rei. p) limit of 2200*F.

e - ECCS Operating B 3.5.2 BASES SURVEILLANCE SR 3.5.2.2 REQUIREMENTS 1 (continued) Verifying the correct alignment for manual, power operated, and ' automatic valves in the ECCS flow paths provides assurance that the proper flow paths will exist for ECCS operation. This SR does not apply to valves that are locked, sealed, or otherwise secured in position, since these were verified to be in the correct position prior to locking, sealing, or securing. A valve that receives an actuation signal is allowed to be in a nonaccident position provided the valve will automatically reposition within the proper stroke time. This Surveillance does not require any testing or valve manipulation. Rather, it involves verification that those valves capable of being mispositioned are in the correct position. The 31 day Frequency is appropriate because the valves are operated under administrative control, and an improper valve position would only affect a single train.

Rev. 1, to delete the term " Annual" and modify the submittal date. This change provides a reference to 10 CFR 50.36a since 10 CFR specifies that the report must be submitted annually and include the results from the previous 12 months of operation. 03 07 A CTS [6.9.1.6], " Annual Radiological Environmental Operating Report" is revised to include specific details concerning the contents of the report. This change is consistent with NUREG 1431.

The requirements related to report submittal are contained in 10 CFR. Since conformance to 10 CFR is a condition of the license, specific identification of this requirement in the TS would be duplicative and is not necessary.
