Palisades Nuclear Plant: 27780 Blue Star Memorial Highway, Covert, Ml 49043 August 6, 1996 U.S. Nuclear Regulatory Commission Document Control Desk Washington, DC 20555 DOCKET 50-255 - LICENSE DPR PALISADES PLANT REQUEST FOR APPROVAL OF REVISION TO INCORE MONITORING CODE (PIDAL)

In accordance with the Palisades Technical Specifications and FSAR, in-core monitoring of neutron flux is currently performed using the PIDAL computer code. Use of the PIDAL code was approved by the NRC in Amendment 144 of the Technical Specifications dated April 3, 1992. In a conference telephone call on April 30, 1996 and a letter dated July 24, 1996, Consumers Power Company (CPCo) discussed its plans for a revision to the PIDAL code, and solicited staff input on the most efficient way to obtain NRC review and approval. It was suggested that a submittal be provided to describe the changes and the technical approach that was taken to validate the revised methodology, with limited technical detail. Based on that submittal, the staff would then determine whether a headquarters review or an on-site audit would be conducted, and would assess what additional technical detail, if any, would be needed

to complete the review. This letter provides the recommended information.

The attached report entitled "The PIDAL-3 Full Core System" describes the code revision. It reviews the methodology used, describes the analyses which have been completed to benchmark the revised code, and provides a sample output computer report. The report also discusses changes in the NRC SER approving use of PIDAL which will be needed to permit use of the code revision.

A CMS' ENERGY COMPANY A-oo l.

The NRC is requested to review this report, conduct any additional audits or other activities deemed necessary, and provide approval to use.the revised PIDAL code.

Approval is requested prior to startup from the upcoming refueling outage, currently scheduled to end in mid-December, 1996. While approval prior to startup is not mandatory, it would provide more efficient use of plant resources by avoiding the need to run both old and new revisions of PIDAL during Cycle 13. It will also permit use of the revised methodology for other analyses scheduled to be performed early in 1997.

In addition, at the staff's earliest convenience, a meeting is requested for our technical staff to meet with NRC technical reviewers to discuss the report and establish a dialogue to facilitate the staff's future activities. This meeting will be coordinated through the Palisades Project Manager.

CPCo looks forward to working with the NRC to support staff review.

1.0 INTRODUCTION

The PIDAL-3 incore monitoring code is the third generation of the Palisades Incore Detector Algorithm capable of determining the reactor core power distribution, peaking factors, and local LHGR on a full core basis. PIDAL-3 is the result of the first major revision to the PIDAL methodology since its SER was issued by the US NRC on April 3, 1992 [ 1]. Modifications encompass the replacement of Siemens Power Corporation's methods (PDQIXTG) for determination of theoretical assembly powers, detector conversion constants, and local peaking factors with SIMULATE-3, an advanced three-dimensional two-group reactor analysis code.

The current Technical Specification limits were developed using PIDAL comparisons from cycles 5, 6, and 7. These were all eighth core symmetric high leakage core designs that shared identical fuel batch sizes and enrichments, and similar cycle lengths. The PIDAL-3 analysis is based on cycles 9, *10, and 11 with low leakage core designs that transition from 299 to 431 effective full power days. In addition, cycles 10 and 11 are quarter core rotationally symmetric.

The movement to low leakage core designs has made it increasingly difficult for Palisades to adequately predict core power distributions with the PDQ/XTG methodology.

Furthermore, current PDQ/XTG quarter core modeling limits our ability to accurately deal with asymmetric power anomalies such as misaligned control rods. Expansion of the PIDAL methodology to include full core SIMULA TE-3 both improves modeling accuracy and provides a tool for monitoring large quadrant power tilts.

Incorporation of SIMULATE-3 methods would significantly reduce measurement uncertainties. However, Consumers Power Company has chosen to simply show that the PIDAL-3 uncertainties are bounded by those currently stated in the Palisades Technical Specifications. This is a conservative approach, but there are still significant core design and operating flexibility gains introduced by the improved accuracy of the SIMULATE-3 methodology over PDQ/XTG.

Therefore, no changes to the Palisades Technical Specifications are required at this time.

The following is a brief summary of the Palisades incore monitoring system and the PIDAL-3

. methodology. Changes from previous PIDAL versions are highlighted in the discussion. Comparisons between PIDAL-3 and the currently licensed PIDAL methodology ar.e made for key parameters such as Assembly Radial Power RMS Deviations, Assembly Radial Peaking Factors (FR A), Total Radial Peaking Factors (FR r), and Total Peaking Factors (FQ). Finally, an analysis of Palisades cycles 9 through 11 shows

. that PIDAL-3 measurement uncertainties are bounded by the current Technical Specification limits.

1.1 PIDAL METHODOLOGY EVOLUTION The full core PIDAL code was first developed by Consumers Power in the early 1990's [l] to replace the eighth core INCA [2] code. There were two driving forces behind the change from INCA to PIDAL.

First, there was a need for quarter core geometry capabilities in order to design cores which met goals established for vessel fluence reduction and increased cycle length. The movement to low leakage core designs in response to reactor vessel fluence caused radial peaking to increase and reduced the margin to the INCA based Technical Specification limits. Margin gained by switching to PIDAL translated directly into greater flexibility in core design and operation. Secondly, it :was expected that the PIDAL system would eventually allow for full detection and measurement capabilities in the event of an asymmetric power anomaly; i.e. misaligned control rods. Unfortunately, this functionality was limited by both quarter core XTG models and SPC supplied quarter core PDQ W-prime and local peaking factor libraries.

In 1995 a new Palisades Plant Computer (PPC) was installed at Palisades. Modifications were made to the PIDAL code to allow it to run on the DEC VAX 4000 workstations, VMS platform. Concurrently, the XTG axial resolution was increased from 12 to 25 axial nodes over the active fuel height to accommodate axial blankets. Reference 8 includes all the changes made to the program and the corresponding 50.59 Safety Review. No overall methodology changes were made. The PIDAL source code was updated and renamed to level 2 (PIDAL-2).

With the introduction of low leakage cores at Palisades, the limits of the coarse mesh nodal code, XTG, have been approached.

As a result of these modeling difficulties with XTG, Consumers Power evaluated SIMULATE-3 and a subsequent effort to incorporate SIMULATE-3 as the theoretical model in PIDAL was irutiated [11]. Upon completion, the new core monitoring code incorporating SIMULATE-3 has been renamed PIDAL-3 and is the topic of this document.

1.2 PIDAL-3 CHANGES The changes required to the PIDAL system to incorporate the SIMULA TE-3 nodal code can be grouped into four general categories:

1)

Integration of SIMULA TE-3 nodal powers.

2)

Integration of SIMULA TE-3 reaction rates.

3)

Integrati_on of SIMULATE-3 pin powers.

4)

Expansion of PIDAL to full core theoretical coupling calculations.

XTG was completely removed from the PIDAL-3 code. PIDAL-3 now uses nodal powers calculated by SIMULATE-3. PDQ based exposure dependent W-primes provided by SPC were used to calculate power from the measured detector fluxes. In the PIDAL-3 calculation train, full core non-depleting rhodium reaction rates are provided by SIMULATE-3 prior to every PIDAL-3 run. Depletion effects are accounted for by a multiplication factor from a polynomial fit describing an exposure dependent self-shielding factor

[12]. Likewise, previous versions of PIDAL utilized PDQ based local peaking factors (LPF) or pin-to-box (PTB) factors provided by SPC. PIDAL-3 utilizes SIMULA TE-3 full core LPFs calculated prior to every PIDAL-3 run.

Finally, the PIDAL-3 radial coupling is exclusively full core as opposed to the XTG quarter core coupling expanded to full core in PIDAL-2. The SIMULATE-3 full core nodal powers, rhodium reaction rates, and LPFs allow the PIDAL-3 system to effectively measure large quadrant power tilts.

2.0 SYSTEM DESCRIPTION The Palisades reactor is a first generation ABB Combustion Engineering (ABBCE) two loop PWR. The core contains 204 fuel bundles and 45 cruciform control blades. The reactor is currently rated at 2530 MWth and the power distribution within the core is measured via self-powered rhodium detectors. There are 45 possible instrumented fuel assemblies. Two of these locations are utilized for reactor coolant level monitoring. Each of the 43 remaining locations contain five rhodium detectors equally spaced at 10, 30, 50, 70 and 90 percent of the active fuel height. Figure 6.1 shows a layout of the Palisades reactor including control blade and incore detector locations.

The incore detectors are manufactured by Reuter-Stokes Incorporated under sub-contract with ABBCE.

The principle of operation involves the conversion of the incident neutron radiation on the emitter material (rhodium) to energetic electrons which migrate through the solid insulation to the collector. The deficiency of electrons in the emitter results in a positive charge on the center conductor of the attached coaxial cable. The rate of charge production produces a low level current which is directly proportional to the rate of absorption at the emitter. This current is monitored by the PPC which performs sensitivity and background corrections while converting the input current to flux. A software interface between the PPC and PIDAL-3 generates the SIMULA TE-3 and PIDAL-3 input files, and initiates the SIMULA TE-3 and PIDAL-3 calculations.

2.1 DATA COLLECTION The PPC is responsible for conversion of the rhodium detector current (amps) to flux (nv).

The conversion uses the K. sensitivity factors provided for each detector by ABBCE. The PPC keeps track of the rhodium depletion and adjusts the K. values accordingly.

As is standard for ABBCE type incore monitoring systems, a linear rhodium detector depletion law is used by the PPC:

K,,(t) = K,,(O) x (I-~:;)

where:

K.;(t)

K.;(O)

~Q; Q"'

- Sensitivity of detector i at time t (amp/nv)

- Initial sensitivity of detector i (amp/nv)

- Acclllilulated charge of detector i at time t (coulombs)

- Total possible accumulated charge of detector i at end oflife (coulombs)

Equation (2.1) is implemented by the PPC as:

where:

1 r=-

Q"'

- Detector Burnup Constant

- Average daily background-corrected detector current for fixed detector i.

(2.1)

(2.2)

Rhodium detector currents (amps) are divided by the K. factor (amp/nv) yielding the detector flux (nv).

These values along with core calorimetric power, control rod positions, and other various plant parameters describing the state of the PCS, are organized into input files for SIMULATE-3 and PIDAL-3 calculations.

2.2 PIDAL-3 CALCULATION TRAIN The Stuclsvik Core Management System consists of two principal codes: CASM0-3 and SIMULATE-3.

Three other Stuclsvik codes provide CASM0-3 and SIMULA TE-3 with essential data:

l) INTERPIN-CS supplies fuel temperature data to CASM0-3 and SIMULATE-3.

2) MICBURN-3 supplies gadolinia fuel pin data to CASM0-3.

3) TABLES-3 processes CASM0-3 cross section data into a library for use in SIMULATE-3.

A SIMULATE-3 calculation is performed for every PIDAL-3 case.

SIMULATE-3 assembly powers, rhodium reaction rates, and LPFs are used by PIDAL-3. Figure 6.2 shows how these codes interact with PIDAL-3 forming the Palisades Core Management System (CMS).

The following sections briefly

. describe the CASM0-3 and SIMULATE-3 methodology, and a detailed discussion of the PIDAL-3 methodology is given in Section 3. 0.

2.2.1 CASM0-3 CASM0-3 is a multigroup two-dimensional transport theory assembly spectrum/depletion code which in various versions has been used by numerous utilities [3]. The code handles a geometry consisting of cylindrical fuel rods of varying composition in a square pitch array with allowance for fuel rods loaded with gadolinia (Gd20 3), via MICBURN-3, burnable absorber rods (B4C), boron steel curtains, instrument tubes, water gaps, cluster con~ol rods, and cruciform control blades. CPCo uses CASM0-3 to generate cross section libraries for XTG and SIMULATE-3. SPC uses CASM0-2E to generate PDQ W-primes and LPFs.

2.2.2 SIMULA TE-3 SIMULATE-3 is an advanced three-dimensional two-group nodal code for the analysis of both PWRs and BWRs which in various versions has also been used by numerous utilities [4]. The neutronics model, QPANDA, employs a fourth-order polynomial representation of the intranodal flux distribution for both the fast and thermal groups [5].. The diffusion equation solution can-be obtained in ~ither two or three dimensions.

SIMULATE-3 requires no adjustable parameters such as albedos or thermal leakage corrections. All cross section information including discontinuity factors and pinwise assembly lattice data are provided by CASM0-3 assembly calculations via the TABLES-3 binary library. SIMULATE-3 performs macroscopic depletion with microscopic depletion of particular fission products while modeling power operation coupled with thermal-hydraulic and Doppler feedback.

The reconstruction of pin-by-pin power distributions is also included.

3.0 PIDAL-3 METHODOLOGY The following sections summarize the PIDAL-3 methodology. Many aspects of the methodology have not changed in the transition from PIDAL-2 to PIDAL-3. The intent is to provide a complete overview of the PIDAL-3 functionality as well as indicating the changes implemented with the PIDAL-3 version.

3.1 INPUT COLLECTION PIDAL-3 receives its input data from four different files:

l)

The Binary Input file, generated by the PPC, supplies the primary input data.

The data is supplied on-line directly via the PPC, or off-line via the FETCH-3 program. This1file contains reactor power, pressure, flow, inlet temperature, and boron concentration. The NI excore powers fractions, CET temperatures, control rod positions, detector fluxes, sensitivities, and fractions of remaining rhodium are also included.

. 2)

The ASCII TSSOR file supplies Technical Specification peaking limits information, number of fuel batches and sub-batches, and Startup & Operations Report data.

3)

The Binary Restart file supplies cycle specific batchwise data and core loading in the first record, and fuel and control rod exposures in each subsequent record. One record is added after each burnup case.

4)

The ASCII Summary file, generated by SIMULA TE-3, supplies all of the full core assembly powers, local peaking factors (pin-to-box), and rhodium reaction rate data. Axially collapsed peak pin and assembly exposures edits as well as linear heat generation rate edits are included for on-line comparisons by PIDAL-3. One file is created for each PIDAL-3 case.

3.2 THEORETICAL CALCULATIONS PIDAL-3 performs a least squares axial curve fit of the SIMULATE-3 nodal powers (204x25) by solving for the boundary conditions with the lowest square sum error, PIDAL-3 then integrates over the 5 detector levels (204x5) to obtain the theoretical detector powers. These theoretical detector powers are used in the W-prime and coupling coefficient calculations (Sections 3.3 and 3.4), and the boundary conditions are used in the axial curve fit of the measured/inferred detector powers (Section 3.5).

The boundary conditions represent the top and bottom axial points where the flux goes to zero. We start at the end of the active fuel height, and iterate on increasing boundary conditions until we find the lowest square sum error.

This routine is the same for all versions of PIDAL, including PIDAL-3. The only difference is PIDAL-3 uses SIMULATE-3 nodal powers instead ofXTG.

3.3 DETECTOR POWER CALCULATIONS The rhodium incore detectors deplete approximately l % per full power month, so corrections are necessary to the detector signal to account for the effects of rhodium depletion. These corrections result from the change in detector self-shielding due to rhodium burnup, and the change in rhodium concentration itself.

The sensitivity correction, described in Section 2.1, accounts for the change in rhodium concentration, but not for self-shielding. Since the detector signal is proportional to the rhodium reaction rate, given a constant flux, the rhodium reaction rate will decrease as the rhodium depletes but not at the same rate due to self-shielding [12].

Corr~ction of the detector signal for depletion of rhodium is accounted for by a multiplication factor, N(t)/N0. N(t) is the rhodium concentration at time t divided by No, the initial (undepleted) rhodium concentration. From equation 2.1, we find the Ks(t)/ Ks(O) ratio is equivalent to N(t)/N0. Therefore, the change in sensitivity corrects for the change in rhodium concentration and the Ks(t)/Ks(O) ratio is equivalent to the fraction of remaining rhodium.

Since the SIMULATE-3 model does notaccount for rhodium depletion, we apply an external correction to the SIMULA TE-3 rhodium reaction rates for self-shielding.

This is slightly more complicated and requires an understanding of the physical phenomena known as self-shielding.

Self-Shielding occurs when a neutron absorbing material of finite thickness is bombarded by neutrons.

Initially, if the neutron flux is approximately thermalized when it reaches the surface of the absorbing material, more neutrons will be absorbed at the surface of the material as compared to the center. For the rhodium detectors this means that more activation occurs on the surface compared to the center.

However, as the surface of the rhodium detector is depleted* the neutrons will begin to "see" more of the interior atoms. The effective diameter of the emitter material is thus decreasing and self-shielding is also.

The overall result is an increase in the effective absorption cross-section of rhodium.

This can be described by the following equation:.

ff a a ;:plaud tP d&fV SSF= -VE ff a a =~-depleted <P d&lV (3.1)

VE The numerator describes the rhodium reaction rate using depleting rhodium detector cross-sections, and the denominator uses non-depleting rhodium detector cross-sections. A function of self-shielding vs.

fraction of remaining rhodium will emerge as the depleted to non-depleted reaction rates are plotted over burnup.

CASM0-3 was used to generate the function of self-shielding factors vs. fraction of remaining rhodium by depleting several fuel types to 100 mwd/kgu to obtain 95% percent rhodium depletion. A 5th order polynomial curve fit of the self-shielding factors vs. fraction of remaining rhodium generated the needed coefficients to calculate the W-primes [12].

These coefficients verify Southern California Edison's assumption tha~ the self-shielding factors are independent of fuel type [6].

To summarize, the detector signals (amps) are corrected for rhodium depletion by the depleting sensitivity values (amps/nv) and converted to flux (nv). The non-depleting SIMULATE-3 rhodium reaction rates are corrected for self-shielding by a self-shielding factor, and the depleting detector signal (nv) is converted to power (MWth) via the W-primes.

The following equations demonstrate how the background and sensitivity corrected signal is converted to power [9].

The average power over a detector is calculated using the following equation:

AVGPOW = (CALPOW) x (HAD)

3.4 RADIAL POWER DISTRIBUTION CALCULATIONS The original PIDAL methodology was based on the ABBCE method CECOR [7]. Over the course of development, several enhancements were made to this methodology, and in general, PIDAL departs from CECOR in the way the inter-assembly coupling is generated.

The underlying assumption in the CECOR method is that the power in any assembly K can be given by the equation:

"J2P(m,J)

P(K *) __

m __

,J - CC(K,J) where:

P(Kj)

P(mj)

CC{Kj)

- Power in assembly K, axial level j

- Power in assembly m, axial level j. Assembly m is adjacent to assembly K.

- Assembly average coupling coefficient for assembly K, axial level j.

Using algebra, CC(Kj) is defined as:

"J2P(m,J)

CC(K,J) = m (

")

PK,J (3.6)

(3.7)

In the Palisades core, there are 204 assemblies (K = 204) and thus the dimension of CC is also 204.

Obviously, P(Kj) is only known for assemblies which contain an operable incore detector. Therefore, a synthesis method is used to determine powers for each of the uninstrumented locations.

It is necessary for the CC(Kj)s to be defined or known. for all core logitj~ms. The CECOR method precalculates the CC(Kj)s from planar depletion studies and fits these values based.on burnup. This would be similar to calculating the CC(Kj)s based solely on the SIMULATE-3 predicted solution.

The problem with this method is that the CC(Kj)s are based solely on prediction and the final full core solution is greatly biased by the predicted solution. Therefore, it was determined that the preferred method would be to somehow infer the CC(Kj)s based on measurement as well.

Once the CC(Kj)s are known, the problem consists of determining the P(Kj)s for uninstrumented assemblies. Equation 3.6 can be rewritten as:

P(K,J) x CC(K,J) = "J2P(m,J)

(3.8) m If equation 3. 8 is written for each uninstrumented assembly K level j, then a set of equations on the order of 204 x 204 results for each detector level. If the unknown P(mj)s are subtracted over to the left. hand side of each equation and the known P(mj)s remain on the right, then a very sparse banded matrix appears on the left, and a known vector appears on the right. Remember (or assume) that the CC(Kj)s are known.

8

Knowing that core locations 4, 9, and 13 are instrumented with detector strings l, 2, and 3 (Figure 6.1),

the first 5 equations are written for each detector level j in expanded matrix-vector notation as:

P1CC1

A.xP=S where:

A p s

- Coefficient matrix consisting of the CC(Kj)s and -1 multipliers to the P(mj)s

- Unknown P(Kj)s and P(mj)s on the left hand side

- Known P(mj)s in a column of sums on the right hand side

= P9

=O

=P4

=O

= P4+P13 (3.9)

What must be found is the vector J5 solution. As alluded to by ABBCE [7], the matrix A is a very sparse banded matrix. Therefore, an efficient way of solving the above set of simultaneous equations should be employed.

ABBCE uses the conjugate gradient method.

PIDAL employs a trustworthy Gaussian elimination routine for sparse matrices. The routine was part of the YALE Sparse Matrix Package available in the public domain [9].

After the vector P has been determined, it is recombined with the known values of P(Kj) and the full core radial power solution for each detector level is obtained.

First, PIDAL-3 calculates the full core assembly average coupling coefficients based solely on the 204 SIMULATE-3 detector powers. Then the SIMULATE-3 coupling coefficients are integrated with the PIDAL-3 measured (known) detector powers to calculate the full ~re measured/inferred detector powers.

The full core measured/inferred detector powers are then used to recalcUlate the full core assembly *average coupling coefficients, which are used to recalculate the final full core measured/inferred detector powers.

I

.As far as coupling is concerned, the PIDAL-3 methodology differs from the PIDAL-2 methodology only in that SIMULA TE-3 detector powers are used to determine coupling coefficients for the full core as opposed to XTG powers used to determine coupling coefficients for the quarter core.

3.5 AXIAL POWER DISTRIBUTION CALCULATIONS Up to this point, the core power distribution is given by a radial power distribution at each of five detector levels. Now, by curve fitting, a continuous function for axial power shape within each assembly is defined. This continuous function can then be used to infer the axial power distribution in the regions not covered by detectors. The general idea is to apply a five mode Fourier fit to the axial data for each assembly, resulting in a continuous function describing the axial distribution.

In order to do this, three assumptions are made:

1)

It is assumed that the axial power distribution shape is adequately approximated by the Fourier sine function. Thus the function may be used for interpolating or extrapolating to compensate for the gross measurements.

2)

It is assumed that the power goes to zero near the top and bottom of the active fuel height. This assumption allows the addition of points (boundary conditions) near the top and bottom to the five known points, effectively improving the curve fit.

3)

It is assumed that the. PIDAL-3 measured/inferred boundary conditions are adequately approximated by the SIMULATE-3 theoretical boundary conditions.

From the continuous function, a power distribution is generated for each assembly consisting of 51 axial nodes. This distribution is then collapsed to 25 axial nodes and even further to a two-dimensional radial and a one-dimensional axial power distribution.

The underlying assumption is that the axial power distribution within an assembly can be given by the sum of the first few Fourier modes. Written in equation form:

N P(z) =Lan sin(mrBz)

(3.10) where:

P(z)

N z

8 h

H n=I

- Point power as a function of core fractional core height

- Number of Fourier modes (5 in our case)

- Unknown coefficients (5 in our case)

-Axial boundary condition, the real core height as a fraction of the apparent core height, W(H+ 28)

- Fractional core height, h/H (between 0 and 1)

-Extrapolation distance, the extra distance past the core edge where the flux apparently goes to zero, (H/2)(1/B - 1)

- Axial position within core in inches

Equation 3.10 assumes that the flux goes to zero at the edge of the active fuel region and therefore does not precisely describe the axial power distribution used by PIDAL. In reality, the flux actually extends beyond the active fuel region, therefore, we shall redefine P(z) to accommodate the actual point where the flux goes to zero:

The unknowns in equation 3.11 and 3.12 are the five a., coefficients. The axial boundary conditions (B) are determined from the SIMULATE-3 theoretical solution by solving equation 3.12 in reverse. The a.,

coefficients are determined using the integrated detector powers.

If equation 3.12 is written in expanded form for each of the five known axial powers in an assembly, then a system of five equations and five unknowns emerge. The system of equations can then be solved simultaneously for the a., coefficients. The resulting a., coefficients are used in equation 3.11 to describe the axial power profile of the assembly.

To summarize:

l)

A loop is performed over each assembly in the core. Within the loop, equation 3.12 is expanded to five terms for each of the five axial powers known for that assembly, resulting in a system of five equations and five unknowns. The system is solved simultaneously and the coefficients, an.

are determined.

2)

After the coefficients for all 204 assemblies are known, a second loop over the assemblies is performed. In this loop, the coefficients in Equation 3.11 are used to determine point powers at

51 equally spaced axial positions in each assembly. When this loop is complete, the full core three-dimensional power distribution consisting of 204 x 51 axial nodes is known.

PIDAL-3 axial power distribution methodology differs from previous PIDAL versions only in that SIMULA TE-3 theoretical nodal powers are used to determine the axial boundary conditions and inferred detector powers instead of XTG.

3.6 TECHNICAL SPECIFICATION SURVEILLANCE CALCULATIONS Based on the data input to PIDAL-3 and the resultant measured core power distributions, the following Palisades Technical Specification (TS) surveillances are performed:

TS 3.1. l.g TS 3.11.1.a TS 3.11.1.b TS 3.11.2.a TS 3.11.2.a-c TS 3.11.2.b TS 3.11.2.c TS 3.23.1 TS 3.23.2 TS 3.23.3 Monitoring axial power shape within limits Incore detector operability Calculation of incore alarms for the incore monitoring system Calculation of target axial offset (AO) and allowable power level (APL)

Excore system calibration for LHGR monitoring Excore system calibration for ASI monitoring Excore system calibration for quadrant power tilt (T Q) monitoring Monitoring LHGR within limits Monitoring radial peaking factors within limits Monitoring T Q within limits The TS limits established for the core average axial power shape (AO or ASI) are designed to ensure that the assumed axial power profiles used in the development of the primary coolant inlet temperature LCO bound* all measured axial power profiles.

The excore detectors monitor ASI continuously and are calibrated to the PIDAL-3 measured core average AO.

The uncertainty analysis for Palisades requires that 75% of the incores are operable for PIDAL-3 to be valid for TS surveillance or incore alarm limit setpoints. In order to protect the core from abnormally high local power densities, the PPC continuously compares the incoming incore detector signals to the alarm setpoints. The alarm setpoint for each detector is simply an alarm factor added to the detector signal. The alarm factor is the minimum margin to the LHGR TS limit measured within the detector level.

Calculation of the target AO and APL, along with the verification that the excore monitoring system is calibrated for monitoring LHGR, ASI, and T Q is performed as part of a single surveillance. The excore ASl monitoring function is calibrated based on the PIDAL-3 target-AO. The excore T Q monitoring function is also calibrated based on the PIDAL-3 target TQ. The PIDAL-3 APL is based on the limiting LHGR and ensures that the LHGR limits are bounding for a given band of AO.

Verification that the excore monitoring system is calibrated consists of comparing PIDAL-3 T Q and AO with corresponding excore TQ and ASI values. If any of the 4 excore channels diverge from PIDAL-3 by more than the allowable margin, the excore channel is declared inoperable and recalibrated.

LHGR limits exist to ensure the peak cladding temperature will not exceed 2200 °F in the event of a LOCA. LHGR is monitored continuously by the incore monitoring system alarm setpoints or by.the excore monitoring system TQ and ASI alarms if the PPC fails. PIDAL-3 must calculate the LHGRs in order to generate alarm setpoints or calibrate excore channels. PIDAL-3 calculates the local peak pin powers by applying SIMULA TE-3 LPFs to the assembly nodal powers. The local peak pin powers are converted to local LHGRs and compared to TS limits.

PIDAL-3 performs a verification of two different radial peaking factors:

FRA -Assembly Radial Peaking Factor Maximum ratio of individual fuel assembly power to core* average assembly power integrated over the total core height, including tilt.

12

FR T - Total Radial Peaking Factor Maximum ratio of the individual fuel pin power to the core average pin power integrated over the total core height, including tilt.

The assembly radial peaking factor is determined from the axially collapsed nodal power distribution.

The total radial peaking factor is determined from the axially collapsed. nodal power distribution multiplied by the LPFs and a ratio of average fuel pins/assembly to the number of fuel pins in each assembly as follows:

FRT = RPD x LPF FRT = FRA x Avg Number of pins in assembly x LPF Number of pins in assembly FRT = Assembly Power x Avg Number of pins in assembly x LPF Avg Assembly Power Number of pins in assembly FRT = Avg Pin Power in assembly x Peak Pin Power Avg Pin Power in core Avg Pin Power in assembly Peak Pin Power FRT = --------

Avg Pin Power in core The relationship of RPO to RPF is as follows:

RPD = RPF x Avg Number of pins in assembly Number of pins in assembly RPD = Assembly Power x Avg Number of pins in assembly Avg Assembly Power Number of pins in assembly RPD = Avg Pin Power in assembly Avg Pin Power in core (3.13)

(3.14)

PIDAL-3 incorporates an innovative method of calculating TQ from the incore detectors. A system of equations is used which defines all the possible combinations of tilt between two-way symmetric detectors for each level. PIDAL-3 also has the ability of calculating integral T Q based on quadrant assembly powers if there are not enough symmetric operable incore combinations. The T Q calculation based on two-way symmetric combinations is preferable since the quadrant assembly powers are a combination of measured and inferred powers and are, therefore, influenced by SIMULATE-3.

13

3.7 PIDAL-3 OUTPUT PIDAL-3 calculates the accumulated assembly exposure distribution based on the total thermal power output over a given time period (MWhrs) and a nodal power distribution representative of the time period.

PIDAL-3 also calculates the accumulated control rod exposures.

4.0 PIDAL-3 VALIDATION The PIDAL-3 calculation results are compared to PIDAL-2 results for cycles 9 through 11.

Key parameters such as Assembly Radial Power RMS Deviations, FRA, FRr, and FQ are considered.

An analysis of the uncertainty in the PIDAL-3 peaking factor calculations is also performed for these reference cycles. The derived uncertainties are compared to those currently approved in the Palisades Technical Specifications. Core loading maps for cycles 9 through 11 are provided in Figures 6.3 to 6.5.

Details of the calculations are documented in Reference 11.

4.1 CALCULATIONS.

Eighty-two cycle 9 exposure cases, 76 cycle 10 exposure cases, and_ l 00 cycle 11 exposure cases were run to generate the PIDAL-3 Restart files. Twelve Uncertainty Analysis cases were then run for cycle 9, twelve for cycle 10, and fourteen for cycle 11. The UNSAT-3 code was used to run the cases; all covering steady-state HFP operation from BOC to EOC. Five uncertainty analysis cases covering 25%. detector failures were also run for each cycle. Finally, two uncertainty analysis cases were run covering an EOC 11 xenon transient and MOC 11 dropped control rod radial power tilts.

4.2 COMPARISONS The cycle 9, 10, and 11 Exposure and Power case comparisons between PIDAL-3 and PIDAL-2 illustrate SIMULATE-J's superiority over PDQ/XTG. The following 3 sets of comparisons were made:

l) PIDAL-2 vs. PIDAL-3 Figures for Cycles 9 to 11:

Figures 6.6a-c:

Cycles 9-11 Assembly RMS Deviations The Assembly Radial Power RMS deviations are considerably lower with PIDAL-3/SIMULA TE-3 over the 3 cycles with a flatter BOC to EOC distribution.

2) PIDAL-~vs. PIDAL-3 vs. SIMULATE-3 Figures for Cycles 9.to 11:

Figures 6.7a-d:

Cycles 9-11 Assembly Axial Offset

The AOs show similar results between PIDAL-3 and PID.AL-2 as expected. SIMULATE-3 is using time step averaging over these cycles and tends to smooth out the transients. For the xenon transient, the SIMULATE-3 End-of-Step (EOS) depletion option was used to recreate the oscillation, but 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months time steps still cause SIMULA TE-3 to diverge after the first 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months .

Figures 6.8a-d:

Cycles 9-11 Assembly Radial Peaking vs. Exposure The FR A is slightly less for PIDAL-3 since SIMULA TE~3 calculates slightly lower peaks than XTG. XTG applies artificial reflector albedos and

assembly coupling factors to manipulate the calculations.

SIMULATE-3 actually models the reflectors and uses discontinuity factors for assembly coupling. The reflector model and discontinuity factors affect the SIMULA TE-3 assembly powers, which generate the PIDAL-3 coupling coefficients, and with the addition of the SIMULATE-3 W-primes, will have an effect on lowering FRA* This is not a consistent effect across all Palisades cycles. For example, the cycle 12 SIMULATE-3 model shows a higher BOC assembly peak than XTG which is much closer to actual measurement.

16

Figures 6.9a-d:

Cycles 9-11 Total Radial Peaking vs. Exposure The FR r is considerably less for PIDAL-3 which is expect~ since FRA is lower and the addition of the average fuel pin-to-assembly fuel pin ratio. Two SIMULATE-3 peaks in cycle 10 appear to be inverted from PIDAL-3. The second peak occurs in exposure step E-39 when power *is reduced to 44%. Two factors could contribute to this; one is time step averaging over the cycle as alluded to earlier, and the second is core stability during the transient. If xenon is causing an oscillation, PIDAL-3 will see it, but the SIMULA TE-3 model could miss it depending on when the snapshot was taken. Again, time step averaging is the likely cause and smaller time steps with captured xenon effects will eliminate the problem.

Figures 6. lOa-d: Cycles 9-11 Total Peaking Factors vs. Exposure The FQ (TPF) is considerably less for PIDAL-3/SIMULATE-3 for the same reason as stated for FRr*

The '2PIN' edit in PIDAL-3 shows the same RMS deviation the* '2RPF' edit shows. This is expected since the only difference between PIDAL-3 and SIMULA TE-3 is the assembly power. The LPFs for both are the same. The '3KWF' (LHGR) edit produces larger deviations since it looks at only the axial peaks in fuel pins between PIDAL-3 and SIMULA TE-3 with no axial integration (Appendix A).

17

4.3 UNCERTAINTY ANALYSIS In order to determine the uncertainties associated with the PIDAL-3 full core monitoring model, it was necessary to employ the appropriate statistical model.

As with all previous PIDAL uncertainty calculations, Siemens methodology (15] was chosen.

Three computer codes are used to generate the statistical analysis data:

The PIDAL-3 program was used to determine the measured and inferred full core detector powers and power distributions required.

The PIDAL-3 program fails each detector string one at a time, and recalculates the power distribution based on inferred data. The uncertainty analysis data is written to the

uncertainty file.

The UNSAT-3 program was used to calculate the F(s), F(sa), F(r), and F(z) uncertainty components. This program reads the Uncertainty file generated by the PIDAL-3 program statistical analysis routines and calculates the deviations, means, and standard deviations required by this analysis. UNSAT-3 also sets up histogram data files for figure plotting (Figures 6.16a to 6. l 9d).

The BWSTAT program was used to calculate the F(L) uncertainty component.

This program was generated to analyze SIMULATE-3 modeling ofB&W critical experiments (13].

Finally, individual component uncertainties were combined in an EXCEL spreadsheet to determine the overall uncertainties as defined by the statistical model (10].

4.4 EFFECTS ON UNCERTAINTIES Included in this analysis is a study of various effects on the final uncertainties such as:

1) Low Leakage Cores

2) Poolabil_ity and. Normality of Data.

3) Failing Large Numbers ofincore Detectors

4) Radial Power Tilts

5) Large Axial OffsetS

The following sections discuss each of these topics.

4.4.1 LOW LEAKAGE CORES One of the consequences of low leakage core designs is that the uncertainties for low power assemblies with relative power fractions (RPF) much less than 1. 0 are inflated-due to higher percent deviations given the same absolute deviation. One possible solution is to use absolute differences instead of percent differences, but the absolute differences in low power assemblies is small compared to average assemblies and would not be conservative. The uncertainty analysis methodology was not changed in order to comply with the NRC expectation that a previously approved methodology be used.

The alternative was to eliminate all assemblies with a RPF less than 1.0. Since the assemblies of interest all have RPFs greater than 1.0, this produces a representative uncertainty that is conservative for peak assemblies, but not so conservative as to penalize the peak unnecessarily (6].

18

4.4.2 POOLABILITY AND NORMALITY OF DATA Before combining data in a statistical analysis, the data must be tested for poolability. Two questions must be answered: First, should the data be poolable? Second, does it make sense? The widely accepted Bartlett Test was used to determine poolability of data within each cycle and across the cycles [16).

In order for data to be poolable, it must be independent and devoid of trends. First, the data generated by the PPC is predictable at steady-state conditions regardless of how often the data is sampled. Therefore, we have truly dependent data and one could significantly increase the degrees of freedom by sampling more data points. This is true of all nuclear plants and is also the case with the original PIDAL uncertainties generated by pooling cycles 5, 6, and 7. Second, since the inception of low leakage core designs, BOC uncertainties tend to be higher than EOC uncertainties since the cores are more heterogeneous at BOC and become more homogeneous at EOC after the peaks have burned out.

With this in mind, it appears that Palisades is unable to pool data within a cycle let alone between cycles.

OPPD had a similar problem and they contacted Charles T. Rombough of CTR Technical Services Inc. for assistance. He advised OPPD to use fewer time points to reduce the degrees of freedom and produce more independent data. OPPD believed that a conservative estimate of 12 time points across the cycle produced independent data. The much lower degrees of freedom is also very conservative [6].

Palisades has concluded that this approach is acceptable for use in the PIDAL-3 application. By sampling Palisades data every 1000 MWD/MfU, we believe the data is independent and we have significantly reduced the degrees of freedom.

The SIMULATE-3 model produced a much flatter assembly radial power RMS deviations across the cycles compared to XTG. (see figure 6.6 a-c) Poolability across cycles 5, 6, and 7 was deemed possible given the similarity in core designs and cycle length. The Bartlett test was not considered in the original SER [l].

The W test and the D-prime test were used to determine normality of data within each cycle [17). The data for cycles 9, 10, and 11 exhibit normal distributions across the cycles [11) (Figures 6.16a to 6.19d).

. 4.4.3 FAILING LARGE NUMBERS OF INCORE DETECTORS Current Palisades Technical Specifications require that 75% of all possible detector locations, with a minimum of two detectors per core level per quadrant be working in order to declare the incore

. monitoring system operable. This is consistent with current ABBCE specifications. It is assumed that the ABBCE standard is referring to plants which incorporate the standard ABBCE full core monitoring methodologies.

In Reference 15, SPC came to the conclusion that the accuracy of an incore monitoring system or methodology depended more on which detectors were operable than on the total number operable. SPC also concluded that it was best to use all available data points in determining the individual component uncertainties, and therefore, did *not go into great detail investigating the effects of large numbers of incore failures on the measured/inferred power distribution. These conclusions are valid because, for random detector failures, there is an equal probability that the well behaved detectors and the non-well behaved detectors would fail.

In order to prove these conclusions, it would be necessary to test every possible combination of failed detectors for a large set of power distributions. From a computational standpoint, this is not practical.

Therefore, a test was devised to.verify that incore failures resulting in 75% detector operability would produce accurate measurements.

A base test case was chosen at the middle of each cycle, and results for each of the component uncertainties were recorded. Five sets of 11 failed incore strings were then chosen using a random 19

number generator. The statistical analysis was repeated for each of the 5 failed sets. The results of the 5 sets were compared to each of the components. The difference was then added to each of the components across all of the cycles. This analysis did not fail 55 individual detectors, since the Fs and FsA statistical analyses only consider fully operable strings. The effects of large radial power tilts with 25% detector failure were examined, but with the inception of SIMULATE-3 full core coupling calculations and the elimination of assemblies with RPFs less than l.O, the consequences of loosing 25% of the detectors is greatly diminished from the original submittal with or without tilt.

The uncertainty analysis for cycles 9, 10, and 11 already eliminates at least 25% of the operable detectors with RPFs less than l.O, and no effect on uncertainties was observed for the PIDAL-3 cases run examining tilted cores [11] and 25% detector failures. For PIDAL-3, an additional 0.0010 is added to the Fs component, and an additional 0.0005 is added to the FsA component. There are no additional penalties for the FR and Fz components. The original PIDAL applied larger penalties for 25% detector failure.

Based on these results, the uncertainties associated with the PIDAL-3 system documented by this report are valid for an incore monitoring system operable with up to 25% of its 215 incore detectors failed.

4.4.4 RADIAL POWER TILTS The original PIDAL methodology determined the F(s) uncertainty component for power distributions with quadrant power tilts up to 5% [14]. The Palisades Technical Specifications allow for full power operation with quadrant power tilts of up to 5%.

The F(s) uncertainty component was recalculated for radially tilted cores. The results showed that in all cases the F(s) value (0.0277) was bounding for quadrant power tilts up to 2.8%. It was also found that the F(s) value depended strongly on the direction and magnitude of the oscillation causing the power tilt. For cores oscillating about the diagonal core axis, the F(s) value was valid for tilts up to 5%. For oscillations about the major core axis, the F(s) value was valid for tilts up to 2.8%. Since the Palisades Technical Specifications allow for full power operation with quadrant power tilts of up to 5%, and it was clear that the overall PIDAL uncertainties were only valid for tilts up to 2.8%, it was necessary to derive a second set of uncertainties for tilts above 2.8%. The current uncertainties are listed in TS Table 3.23-3.

With the inception of SIMULATE-3, radial power tilts between 2.8% and 5.0% do not require additional uncertainties since SIMULA TE-3 and PIDAL-3 can monitor the full core including dropped control rods.

The major limitation of the original submittal was a quarter core XTG model, and quarter core PDQ W-primes and LPFs. No effect on uncertainties was observed for the PIDAL-3 cases which examined tilted cores [11].

4.4.5 LARGE AXIAL OFFSETS The PIDAL-3 uncertainty analysis contains an actual power transient which produced a xenon driven power oscillation. The movement of control rods and changes in boron concentration have the greatest effect on SIMULATE-3's ability to reproduce the transient. The major limitation is due to the frequency of snapshots from the PPC (1 per.hour).

Too many evolutions can occur within each hour for!

SIMULATE-3 to accommodate over the entire transient. For example, control rod movements 10 minutes passed the hour produce very different results than those 10 minutes to the hour. Therefore, as a transient continues PIDAL-3 and SIMULA TE-3 begin to diverge. Ten to fifteen minute time steps are ctirrently available with the PPC and will improve the uncertainties.

20

4.5 RESULTS Overall the changes made to the PIDAL-3 code produced significant differences in the output compared to the PIDAL-2 code. The fundamental methods used in calculating the coupling coefficients (full core vs.

quarter core), W-primes (SSFs and rhodium reaction rates), and LPFs (pin ratio in equation 3.13) have significantly changed. The theoretical data produced by SIMULA TE-3 are far superior to the PDQ/XTG data. This is expected since SIMULA TE-3 is an advanced diffusion theory nodal code compared to the very old PDQIXTG methodology.

The uncertainties also reflected SIMULATE-3's superiority over PDQ/XTG. The SIMULATE-3 model greatly reduced the component uncertainties even without eliminating all assemblies with RPFs less than

1. 0. The mean also shifted closer to zero thus allowing for the continued use of a zero bias as assumed in the original uncertainty analysis, and the standard deviations were normally distributed about the mean.

The degrees of freedom were greatly reduced by limiting the time points to approximately 1000 MWD/MTU to improve the independence of the data and allow for pooling within the cycle. Cycles 9, 10, and 11 were not poolable across the cycles, and cycles 5, 6, and 7 were not analyzed for poolability in the original uncertainty analysis.

Statistical analysis results can be seen in Figure 6.15, and the corresponding histograms in Figures 6.16a to 6. l 9d show the standard deviation distributions about the mean.

All of the 95/95 uncertainty components analyzed by UNSAT-3 are lower than the original uncertainties [10,11,18] for cycles 5 through 7. The degrees of freedom as discussed in Section 4.4.2 were significantly reduced, and PIDAL-3 is still bounded by the original uncertainties.

21

5.0 CONCLUSION

The PIDAL source code and all support codes were updated and renamed to level 3, version 1.00, date 05/01/96 due to the extensive modification on each code to accommodate SIMULATE-3.

The total rewrite of the interface with theoretical data is due to the installation of SIMULA TE-3 and the full core coupling calculation.

The final results produced significant differences when compared to PIDAL-2 as expected. The ability of PDQ/XTG to reproduce measured plant data is severely limited due to the present day low leakage core designs with higher peaking. SIMULA TE-3 results are far superior.

The PIDAL-3 program has been validated per Reference 11, and the uncertainty analysis results are bounded by the present Palisades Technical Specification values (TS Table 3.23-3). This proposed update to the PIDAL SER will not require Technical Specification changes at this time, but the following changes will occur when the CE Standard Technical Specifications are submitted in the first quarter of 1997:

Palisades Technical Specification Table 3.23-3 will be moved to the COLR with the addition of Table 2.3 since the CE Standard Technical Specifications do not include uncertainty values. The. definition for Total Radial Peaking Factor (FRr) will also be rewritten for simplification as follows:

FR r Total radial peaking factor shall be the maximum ratio of the individual fuel pin power to the core average pin power integrated over the total core height, including tilt.

After the CE Standard Technical Specifications are issued it is our intent to remove the additional uncertainties for radial tilts above 2.8%. Sections 4.4.3 and 4.4.4 previously stated that the PIDAL-3 methodology, with the full core SIMULATE-3 model, has the ability to measure radial tilts (e.g. dropped control rods) without any additional penalty to the uncertainties for up to 5% quadrant power tilts.

Since it is Palisades intent to reinsert incore detectors starting with cycle 14, we intend to observe the additional penalty to the uncertainties until we obtain enough data to verify the effects of reused incore detectors on the PIDAL-3 uncertainty analysis.

APPENDIXB SUGGESTED SER REVISION B.l

2.0 BACKGROUND

Palisades is a first-generation Combustion Engineering (CE) pressurized water reactor (PWR) with a unique core design consisting of 204 fuel bundles and 45 cruciform control blades. The core power distribution is monitored by self-powered rhodium incore detectors in a maximum of 45 instrumented fuel assemblies. Each detector location contains five equally spaced rhodium detectors ( 40cm in length) with centers at 10, 30, 50, 70, and 90 percent of the active fuel height. Currently, only 43 incore locations are available, since two locations are reserved for use by the reactor vessel level monitoring system.

The rhodium detectors, of standard design for CE type incorC? monitoring systems, are manufactured by Reuter-Stokes of Canada. These rhodium detectors produce a current directly proportional to the incident neutron flux at each detector location by a neutron-beta reaction. This current is passed to the Palisades plant computer (PPC) and converted from an analog to a digital signal.

The PPC performs the background and depletion sensitivity corrections, and provides all the necessary plant data to the PIDAL-3 incore analysis system.

The incore detector signals (amps) measured by the PPC are corrected for background noise and depletion sensitivity {amps/nv), and converted to flux (nv). The integral powers over each axial detector segment are then determined by the application of signal-to-power conversion ratios (W-primes). The W~primes are supplied by SIMULATE-3, an advanced three-dimensional two-group diffusion theory nodal code, as.

part of the incore monitoring system. The PPC provides SIMULATE-3 with all the necessary plant data, and SIMULATE-3 provides PIDAL-3 with all the necessary theoretical data.

The assembly powers for uninstrurnented locations are inferred using coupling coefficients to adjacent instrumented neighbors. This process allows the determination of a measured or inferred radial core power distribution at each of the five axial detector levels. A detailed axial power shape is then inferred using a five mode Fourier curve fit to the five level power integral for each assembly.

The incore analysis program is executed to determine the measured reactor core power distribution.

Based on this analysis the following TS surveillances may be performed:

TS Section 3.1.1.g 3.11.1.a 3.11.1.b 3.11.2.a 3.11.2.a-c 3.11.2.b 3.11.2.c 3.23.1 3.23.2 3.23.3

Specific Surveillance Item Monitoring axial power shape within limits Incore detector operability Calculation of incore alarms for the incore monitoring system Calculation of target axial offset (AO) and allowable power level (APL)

Excore system calibration for LHGR monitoring Excore system calibration for ASI monitoring Excore system calibration for quadrant power tilt (T Q) monitoring Monitoring LHGR within limits Monitoring radial peaking factors within limits Monitoring T Q within limits Technical Specification 3.1.1.g establishes limits on the core average axial power shape to ensure that the axial power profiles assumed in the development of the primary coolant inlet temperature Limiting Condition for Operation (LCO) bound the measured axial profiles. The axial power shape, referred to as the axial offset (AO) or the axial shape index (ASI), is defined in TS 1.1 as the power in the lower half of the core minus the power in the upper half of the core divided by the sum of the powers in the lower half and upper half of the core. The excore system continuously monitors the ASI and is calibrated to the incore analysis program measured core average AO.

Technical Specification 3.11.1.a requires the determination of the operability of sufficient incore instruments. (ICI) to allow the incore analysis program to perform the required TS surveillances and the B.2

generation of the PPC incore alarm set points. Currently, at least 75 percent of the individual detectors must be operable including at least two incores per axial level per core quadrant.

Technical Specification 3.11.l. b requires the generation of PPC high alarm set points in order to protect the core from high local power densities by continuously comparing the directly measured ICI signals to the alarm set points. The alarm limits, one for each of the* five axial detector levels, are calculated by the incore analysis program and are equivalent to the minimum margin to the LHGR TS limit as measured for each detector level.

Technical Specification 3.11.2 requires the calculation of the target AO and the allowable power level (APL), along with the verification that the excore monitoring system is calibrated for monitoring the LHGR, the ASI, and the quadrant power tilt (T Q). The target AO is derived from the core average AO measured by the incore analysis program and provides the basis for calibrating the excore detectors ASI monitoring function.

The measured power distribution also provides the target or baseline quadrant power tilts which are used to calibrate the excore quadrant power tilt monitoring function. The APL is calculated based on the limiting measured LHGR and ensures that the core LHGR limits are protected within a given band of the AO.

The TS 3.73.1 LHGR limits ensure that the peak cladding temperature (PCT) will not exceed 2200 °F in the event of a loss-of-coolant accident (LOCA). The LHGR (and the related three-dimensional nuclear pin peaking factor FQ) is continuously monitored by either the PPC incore high alarm set points or by the excore monitoring system axial shape index (ASI) and allowable power limit (APL) alarms.

In order to calculate the incore alarm set points and to calibrate the excore monitoring system, the incore analysis program must calculate the local LHGR by applying local peaking factors (LPF) or pin-to-box (PTB) factors to the measured/inferred three-dimensional nodal power distribution.

These LPFs are also supplied by SIMULATE-3 as part of the incore monitoring system. The calculated local peak pin powers are converted to local linear heat rates for comparison with the TS limits.

The TS 3.23.2 radial peaking factor limits ensure that the assumptions used in the analyses for establishing margin to DNB, LHGR and for the thermal margin/low-pressure (TM/LP) and the variable high power RPS trip set points remain valid. This requires verification of the two radial peaking factors defined by TS 1.1 :

FR A The assembly radial peaking factor is the maximum ratio of the individual fuel assembly power to the core average assembly power integrated over the total core height, including tilt FR r The total radial peaking factor is the maximum ratio of the individual fuel pin power to the core average pin power integrated over the total core height, including tilt.

The assembly radial peaking factor is determined directly from the two-dimensional assembly radial power distribution resulting from the axially collapsed three-dimensional measured/inferred nodal power distribution. The total radial peaking factor is determined by multiplying. the three-dimensional measured/inferred nodal power distribution to the three-dimensional LPFs and the ratio of the average number of pins/assembly to the number of pins in the assembly, then collapsing it axially to two dimensions.

Technical Specification 3.23. 3 requires verification of the quadrant power tilt defined by TS 1.1 to ensure that the design safety margins are maintained:

The quadrant power tilt is the maximum positive ratio of the power generated in any quadrant minus the average quadrant power, to the average quadrant power.

B.3

Operation is not restricted with tilts up to 5 percent. Larger tilts, not to exceed 10 percent, require verification of radial peaking factor limits and/or reduction to less than 85 percent of rated power. Tilts exceeding 10 percent require reduction to less than 50 percent power and verification of radial peaking factor limits and tilts greater than 15 percent require shutdown to hot standby conditions within 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months .

The TS verification that the excore system is calibrated is performed by comparing the measured core average AO and quadrant power tilts to the corresponding vaiues recorded by the four power range (safety) excore detectors. If any excore reading differs from the corresponding incore measured value by more than the allowable margin, that channel is declared inoperable and is recalibrated based on the incore measurements.

Each time the TS requirements are performed, a complete set of det~tor alarm limits are created. These alarm limits are loaded into the PPC at least once every 7 days for use until the next required update.

3.0 EVALUATION 3.1 Methodology General The PIDAL-3 program always models the reactor power distribution on a full-core basis with quarter core symmetry. The incore data collection procedure, including the background and depletion corrections is equivalent to the previous monitoring programs. The incore detector signal-to-power conversion using SIMULATE-3 is equivalent to the CECORLIB program used to generate the W-prime and LPF library for CECOR (Ref. 8). The axial power distribution interpolation technique, including the use of theoretical axial boundary conditions derived using the NRC-approved SIMULATE-3 nodal model (Ref. 9), is similar to the previous monitoring programs. Fuel and control rod exposure calculations, and the TS analysis procedure are equivalent to the previous monitoring programs.

The significant differences between the PIDAL-3 methodology and the original PIDAL methodology are:

1) Theoretical Nodal Power Distribution

2) Incore Detect~r Signal-to-Power Conversion

3) Local Peaking Factors and Pin Ratio

4) Full <;:ore Theoretical Coupling Coefficients Theoretical Nodal Power Distribution The original PIDAL program used XTG to determine the theoretical nodal powers on a quarter core basis.

This limited PIDAL's ability to measure radial tilts since the XTG model was limited to quarter core. The PIDAL-3 program uses SIMULATE-3 to determine the theoretical nodal powers on a full core basis. This allows PIDAL-3 to accurately measure radial tilts since the SIMULATE-3 model is full core and will accept individual dropped control rods.

Incore Detector Signal-to-Power Conversion The original PIDAL program used PDQ to determine the theoretical W-primes on a quarter core basis.

This limited PIDAL's ability to.measure radial tilts since the PDQ model was limited to quarter core and to group 4 control rod insertion only.

The PIDAL-3 program uses SIMULATE-3 to determine the theoretical W-primes on a full core basis at any power. This allows PIDAL-3 to accurately measure radial tilts at any power since the SIMULATE-3 model is full core and will accept individual dropped control rods.

B.4

Local Peaking Factors and Pin Ratio The original PIDAL program used PDQ to determine the theoretical LPFs on a quarter core basis. This limited PIDAL's ability to measure radial tilts since the PDQ model was limited to quarter core and to group 4 control rod insertion only. The original PIDAL program did not account for different numbers of fuel pins/assembly. This caused PIDAL to over-measure pin powers in assemblies with more pins than the average and under-measure pin powers in assemblies with less than the average.

The PIDAL-3 program uses SIMULA TE-3 to determine the theoretical LPFs on a full core basis at any power. This allows PIDAL-3 to accurately measure radial tilts at any power since the SIMULA TE-3 model is full core and will accept individual dropped control rods. The PIDAL-3 program accounts for different numbers of fuel pins/assembly and hence, accurately measures the peak pin to the average pin of the core (Ref. 11).

Full Core Theoretical Coupling Coefficients The original PIDAL program determined the full core power distribution based on XTG quarter core coupling integrated with measured powers and expanded to full core coupling. This limited PIDAL's ability to measure radial tilts since the XTG model was limited to quarter core.

The PIDAL-3 program determines the full core power distribution based on SIMULATE-3 full core coupling integrated with measured powers. This allows PIDAL-3 to accurately measure radial tilts since the SIMULATE-3 model is full core.

3.2 Uncertainty Analysis General As defined in the TS and discussed in Section 2.0, the peaking factors of interest for Palisades are FQ, FRA, and FR r. Three separate components for the uncertainty associated with determination of the above peaking factors are considered as follows:

1)

The box measurement component is

defined as the uneertainty associated with measuring segment powers in the detector locations.

2)

The nodal synthesis component is the uncertainty associated with using the radial and axial power distribution synthesis techniques employed by PIDAL-3 to calculate a nodal power. Specifically, the uncertainties associated with the radial coupling to the uninstrumented locations and the. aXial curve fitting used to obtain an axial power shape from the five discrete detector powers.

3)

The pin-to-box component is the uncertainty associated with using the SIMULATE-3 LPFs to represent the pin power distribution within each assembly.

To adequately address the above uncertainties, it is necessary to mathematically re-define the individual peaking factors in terms of these components. Since the current fuel vendor for Palisades is Siemens Power Corporation (SPC), CPC chose to utilize the SPC breakdown as described in their St. Lucie-1 uncertainty analysis (Ref. 10).

In the uncertainty analysis of the PIDAL-3 statistical model (Ref. 12), CPC has separated the above.

factors into iridividual components which can be investigated and quantified independently.

These components are statistically recombined into the appropriate uncertainty values for the TS surveillance requirements.

B.5

The specific form of the peaking factors used by CPC is as follows:

F(q)

= F(s)

F(r)

F(z)

F(L)

F(rT)

F(rA) where:

F(s)

F(sa)

F(r)

F(z)

F(L)

= F(sa)

F(r)

F(L)

= F(sa)

F(r)

= Relative power associated with a single detector measurement.

= Relative power associated with the average of the detector measurements within a single assembly.

= Ratio of the assembly relative power to the relative power of the detector measurements within that assembly.

= Ratio of the peak planar power in an assembly to the assembly average power.

= Peak local pin power within an assembly relative to the assembly average power.

CPC uses standard forms for the sample means ( x ), standard deviations (s), and root-mean-square (rms) differences. Based on the mean, the standard deviation, and the sample size, the 95/95 tolerance limit (bias plus-or-minus the reliability factor) was determined for each component, assuming that the percent difference (error) between calculated values and measured data are normal distributions. The individual variances are defined in standard terms and are combined statistically by assuming that the individual uncertainty components are independent.
