- Enclosure 9 (Step 6.10)
The inspector reviewed the calculations for Group 7 integrated regulating rod worth.and noted that the.value given in Enclosure 9,
- Data Sheet 2, for the rod worth of Group 7 from 95% WD (withdrawn)
to 100% WD was 0.052% AK/K. This value was indicated as being taken from Step 6.7. However, the data in Step 6.7 indicated that 0.052%
AK/K was the worth of Group 7 from 93% WD to 100% WD. As a result,

the worth of Group 7 from 93% WD to 95% WD was added twice in the calculation of the integral control rod worth for Group This is considered to be a violation of 10 CFR 50,' Appendix B, Criterion XI and an example of an item of noncompliance (346/85009-01a(DRS)). The licensee demonstrated that the result of the corrected calculation of Group 7 integral rod worth was still within the acceptance criterio In addition, after the
.date at which ST 5010.03 was completed and prior to the beginning of this-inspection, the licensee had instituted measures requiring independent review of test results. Therefore, no further response is require Enclosure 11 (Steps 6.12 and 6.13)
(1) The inspector reviewed the calculations related to the ejected rod worth meacurement and noted that the value given as the regulating rod worth at 58% WD was 0.540% AK/K whereas, from the data in Step 6.10 the correct value was 0.503% AK/ Therefore, the licensee calculated a value of 0.569% AK/K for the Measured Ejected Rod Worth Using Rod Swap, whereas this value should have been 0.606% AK/K. Based on the above, the Ifcensee performed an incorrect calculation for ejected rod-worth which is considered to be a violation of 10 CFR 50, Appendix B, Criterion XI and an example of an item of noncompliance (346/85009-Olb(DRS)). The licensee has subsequently reperformed the calculations using the correct values and instituted measures-for independent review of results and, therefore, no further response is require (2) Although the initial rod position was established correctly for the ejected rod worth measurement, the basis used to establish this rod position was not identified in the procedur The licensee intends.to modify the procedure to identify acceptable initial conditions for rod positio This is an open item pending procedure revision and subsequent NRC review (346/85009-02(DRS)).

Pevision 2, performed on February 13, 1985, in order to examine the licensee's procedure for measuring the power coefficient of reactivity and the results of the most recent measurement. The inspectors verified that prerequisites, precautions, and plant conditions were. met, calculations were correct, values obtained were within acceptance criteria, and results were reviewed in accordance with administrative requirement No items of noncompliance or deviations were identifie . Moderator Temperature Coefficient Measurement The inspectors reviewed ST 5010.03, " Post Refueling Physics Testing,"
Revision 6, Enclosure 7, and ST 5010.02, " Moderator Temperature Coefficient Measurement," Revision 6, in order to examine the adequacy of the licensee's procedure for measuring the temperature coefficient of reactivity and the results of the most recent measurements. The following items were noted during the revie The inspector attempted to check the calculations performed for ST 5010.02, " Moderator Temperature Coefficient Measurement,"
(at power) but received a different result from the license The licensee calculated the reactivity change for the second measurement of the temperature coefficient to be -0.07198% AK/K/*F while the inspector (using the licensee's numbers) calculated the same reactivity change to be. -0.07398% AK/K/*F. Further, for the same second measurement, the' licensee utilized an incorrect value fo xenon (Xey) of -2.585% AK/K. From the numbers recorded on page 9, the corrett value should ba -2.576% AK/K. Based on the above items, the licensee performed an incorrect calculation for moderator temperature coefficient which is considered to be a violation of 10 CFR 50, Appendix B, Criterion XI, and an example of an item of noncompliance (346/85009-01c(DRS)). This incorrect value was also used in PT 5175.03, " Power Doppler Coefficient." The licensee has subsequently reperformed the calculations using the correct values and instituted measures for independent review of results and, therefore, no further response is required, ST 5010.03, Enclosure 7, regarding measurement of the temperature coefficient was performed with control rod group 7 90% withdraw The results, however, were compared to a Physics Test Manual table which is based on control rod groups 1 through 7 at 100%

Thermal Power Evaluation The inspectors reviewed ST 5030.01, "RPS Daily Heat Balance Check,"
Revision 7, and PT 5131.02, " Verification of. Computer Calculations,"
Revision 0, in order to assess the technical adequacy and check.the-evaluation of results. In addition, the inspectors reviewed the circumstances' surrounding the exceeding of a Technical Specification Limiting Condition for Operation involving the determination of thermal
. power. The inspectors' findings are as follows:
. The results associated with ST 5030.01 can be calculated either entirely by hand or by inputting values by hand into a RAMTEK computer which then performs the calculation and provides a printout. The input values required for these calculations are obtained from the plant's process computer which assigns a specific plant parameter output.to a unique computer point. The inspectors noted that the hand calculation and the.RAMTEK calculation data sheets'for.ST 5030.01 were filled out such that the labeling of the computer points did not always match the values used. Although, in some cases, the' individual performing the surveillance test labeled the source of the data, in other cases this was not done and, for these cases, an independent reviewer is unable to determine which computer points were used in the calculations. Further, while the data sheet from ST 5030.01 records reactor coolant pumping power in
, megawatts, the licensee's designated reviewer noted that the input
! for the RAMTEK program requests these inputs in kilowatts. The individuals performing the heat balance, however, were simply
- transferring the numbers from the data sheet to the. computer input without accounting for the megawatt / kilowatt difference. The licensee had recognized these-difficulties with the heat balance determination and was in the process of a procedure or program revision to. correct the difficulties. The inspector has no further concerns in this are ' Following the inspectors' request to review all of the data
-associated with heat balance determination of thermal power, the licensee acknowledged that PT 5131.02, which performs a manual check of computer heat balance, had not been performed during the initial startup and run for Cycle 5 which lasted from January 15,-

Further, the Reload Report for Cycle 5 requests special emphasis be placed on.startup testing and, i particular, a heat balance be performed as early as possibl 'While the licensee may have met the wording of the reload report by L 5

appear.to the inspectors to indicate special emphasis was placed !
on startup testing. Failure to perform PT 5131.02 when required I is considered to be a violation of 10 CFR 50, Appendix B, Criterion V, and an item of noncompliance (346/85009-03(DRS)). On April 14, 1985, the steam generator No. 1 feed flow transmitter (FTSP282) which indicates on computer point F673, was determined to have filled with water and faile The transmitter was tagged out
.and a temporary change to Surveillance Test ST 5030.01 was written which deleted computer point F673 from the average of the four feed flow readings in calculating thermal power by heat balance. While the tenporary change deleted F673 from the procedure for a manual heat balance, operations and Instrumentation and Calibration (I&C)
personnel involved in the above actions apparently did not realize that the failed feed flow indicator still inputted to the computer calculation of thermal power by heat balanc The Engineering Department which was knowledgeable of the computer inputs was unaware that the flow transmitter was 'out of service. From April 16 until discovery that the computer heat balance was incorrect on April 20, 1985, the ifcensee relied primarily on the computer heat balance for determination of reactor thermal power. On April 17, 1985, the licensee did check the thermal power determination as a routine part of comparing feed flow, power by heat balance, and generated megawatts electric during a startup. At this time, however, power as determined by computer heat balance was 80% to 90%. Coincidentally, the failure of the feed flow transmitter was such that the' transmitter output was indicating a feed flow equivalent to 80% to 90% power. The instrument is a Bailey transmitter with a -10 volts to +10-volts rang When the instrument fails, it fails to 0 volts. The instrument is not linear and calibration records from a calibration on January 11, 1985, were such that 0 volts should'be equivalent to just under 80% power with a *.5% of full scale tolerance. After the fact '
examination of the feed flow readouts indicate the transmitter for L computer point F673 failed to an indicated 87% power. Since this
,
was roughly equivalent to the actual power level on April 17, 1985, L the error was masked from the checks that were made.
(
l Subsequently, the licensee continued to increase power. As power increased further away from the fixed feed flow transmitter output of approximately 87% power, the computer heat balance calculation y became biased low such that actual thermal power was higher than
! thermal power as determined by computer heat balance. During this l time nuclear instrumentation (NIs) was adjusted to be equal to l thermal power by computer heat balance within an allowable band as l determined from Figure 1 of ST5030.01. This figure allows NIs to
'
indicate higher than thermal power but not lowe From 11:50 a.m. on April 19, 1985, to 2:50 a.m. on April 20, 1985, the licensee recorded reactor coolant flow rate values in the operator logs from 1.79% to 2.065% lower than the reactor coolant

the above period, reactor thermal power was-required to be limited to less than 96.42% to 95.87%. At 5:18 p.m. on April 19, the licensee stopped increasing power at 95.5% as determined by computer heat

balance in order to stay below the thermal power limit. However, the coe.puter, heat-balance was incorrect in that it still utilized an input from the failed feed flow transmitter. The licensee maintained approximately this power level until 2:20 a.m. on April 20, 1985, when operations personne12 realized electric output in megawatts (MWe)
was too high for the indicated thermal power. Power level by core differential temperature indicated 99.2% and MWe showed 903 MWe.which is-about 98%. A manual calculation of thermal power was performed indicating an actual. power of 98%. The licensee then reduced power-to 95.4% by manual. secondary heat balance calculation. . The Limiting Condition for Operation (LCO) from Technical Specification 3.2.5 was

[ The inspector also'noted that one of the key parameters invc1ved in exceeding the LCO, reactor coolant flow rate, is believed by the licensee and.the NSSS vendor, Babcock & Wilcox (B&W), to be an artificial indication of low reactor coolant flew rat In the l Reload Report for-cycle 5, the licensee and B&W describe how adding burnable poison-rod assemblies (8PRAs) to.previously unblocked~
channels'causes less coolant. flow to bypass the core and more flow through the core area. However, the increased resistance to flow

across the reactor produces a lower reactor coolant flow in the loops for the equivalent pumping power as compared to previous cycles. The licensee contends this lower loop flow is actually equivalent to full flow through the core due to more coolant passing through the core area. The licensee had previously submitted an amendment to the Technical Specifications to reflect this fac Based on the above discussion, the licensee believes
'
that while the LCO on power level versus flow rate was actually exceeded, the safety impact was minimal in that the full core flow was present even though indicated loop flow was lower than the reactor coolant flow rate limit of Technical ~ Specification 3. Further actions regarding the above issue are expected to be addressed in a subsequent. Inspection Repor No additional items of noncompliance or deviations were identifie ! Operational Event Follow-up - Flux / Delta Flux / Flow Reactor Trip At 3:53 a.m. on April 24, 1985, while operating at 95% power as indicated by computer heat balance, the reactor tripped on flux / delta flux / flo All-four channels actuated within 15 milliseconds of each other. At the time the trip occurred the following conditions existed:
. Plant temperature, pressure, and pressurizer level were normal
. Plant was stable with Integrated Control System _(ICS) in automatic
. Power was 95% by computer heat balance (. . Nuclear Instrument (NI) power indicated 98% -
. Flux Imbalance was -2.0%
L '
L The flux / delta flux / flow trip uses flux imbalance signals from nuclear
- instrumentation and Reactor Coolant System (RCS). flow signals from primary instrumentation to modulate a flux. level trip setpoint. The result is a variable trip setpoint based on instantaneous values of flux
, imbalance or flow. The technical specification setpoint limit-is 106.8%
L power based on flow of 100% with a flux imbalance range of -18.2% to.
l +18.2%.~
The licensee conducted al post trip analysis to determine the cause of the reactor trip and provide corrective action if require The following was identified:

. RCS flow was 98% due to the use of BPRAs in the reload cor The use of the BPRAs reduced core bypass flow, raised the differential pressure across the core, and reduced loop flo Since loop flow was reduced, the voltage input to the RPS was reduced and a~ corresponding reduction in trip setpoint-automatically occurre . New flow transmitters were installed during the-refueling outage and sensitivity and noise were creating an output that oscillated by as much as two percent. This oscillation in flow signal caused a corresponding oscillation in the trip setpoin The licensee determined that the low 100% flow setpoint in existence, the reduction in setpoint due to 98% flow, and the further periodic reduction caused by flow signal oscillations were cumulative. On a flow signal negative oscillation, the existing 98% flux signal exceeded the trip setpoint and the reactor trippe The licensee has taken the following corrective action:
. Reduced plant power to 90% by heat balance to avoid further challenges to the protection syste . Conducting an investigation into an event at the Rancho Seco station in which all four NI channels simultaneously spiked high resulting in a high flux trip. This event is somewhat similar in that all four protection channels tripped within milliseconds of each othe . Contacting the vendor (Rosemount) for assistance in reducing the noise and oscillations in the transmitter outpu . A technical specification change has been requested which will allow credit for the increased core flow and use of the l- present 98% indicated flow as the 100% flow baselin The

The inspectors had the following comments: The limit for the nuc1 car enthalpy rise hot channel factor for PT.5175.02.03 at 75% power was incorrectly calculate This' was subsequently recalculated by the licensee and determined to have'no impact on the acceptability of the. tes This simple error indicates a lack of effective review and is considered to be a violation of 10 CFR 50, Appendfx B, Criterion XI, and an example of an item of noncompliance (346/85009-01d(DRS)). Deviation for radial peaking and total peaking factors is determined by comparing the highest measured value against the highest predicted value over an eighth-core map. This frequently results in comparing the measured values of one fuel assembly to the predicted values of a different assembly.

Estimated Critical Boron Concentration Calculations On April 13, 1985, during a reactor startup, the reactor went-critical at a regulating rod position'of approximately 180%
withdrawn (300% withdrawn is equivalent to all three regulating rod groups being fully withdrawn) which was before it was predicted to go critical based upon a computer printout dated April 8,198 The printout indicated an estimated critical regulating rod position of 192 to 273% WD-(withdrawn). As required, the operators reinserted the' regulating rods until they were fully inserted into the core and contacted the Nuclear and Performance Engineer (NPE). Based upon the fact that there was a difference of approximately 40 ppm between predicted and actual all rods out boron concentration, as documented in Surveillance Test ST 5010.03 for Cycle 5, the NPE recommended that the reactor coolant system boron concentration be increased by approximately 40 ppm. After making this adjustment, the reactor went critical within the limits of the estimated critical regulating rod positio Technical Specification 4.1.1.1.2 required that the overall core reactivity balance be compared to predicted values to demonstrate agreement within i1% AK/K at least once per 31 Effective Full
