The Labcoch 6 Wilcox Cenpany has evaluatcd thc thern,1-: d7 raulie Ce a;a of t:m !v.vic-Besse Nuclear Power Station Unit No. 1 and has identified thernal margins which can be used to offset the DNBR reduction uhich results from fucl rod bcuing. The rod bow versus burnup curve used for this evaluation is consistent with that given in Reference (1) and in Section 3.2 of the " Interim Safety Evaluation Report on Ef fects of Fuel Rod Bowing on Thernal :fargin Calculations for Liaht Water Reacters". The red bou versus burnup curve has been used in conjunctica uith the Uestinghouse curve of DSER reductien, versus rod bcu to deternine the reduction in DMER as a function of burnsp. In daterrd n-ing a rod bcu penalty, the following thermal cargins have been identified to help of f. e t the DNER reduction: | The Labcoch 6 Wilcox Cenpany has evaluatcd thc thern,1-: d7 raulie Ce a;a of t:m !v.vic-Besse Nuclear Power Station Unit No. 1 and has identified thernal margins which can be used to offset the DNBR reduction uhich results from fucl rod bcuing.

The 12 hour periedic surveillance of these parameters through instru-ment readout is sufficient to ensure that the parameters are restored within their limits following load changes and other excected transient 4 operation. The 18 month pericdic measurement of the RCS total ficu rate using delta P instrumentation is adequa:e to detect ficw degradatica and ensure correlatien of the ficw indication channels with measured ficw such that the indicated percent ficw will provide sufficient verification j of flow rate on a 12 hour basis.

the decreased loop resistance, which resulted in more loop flow. | |||

18.4 kw/f t wcs used which is the 6-foot LOCA linit reported in BAW-10105. The results of the analysis are presented in Figures 4-6 and 4-7 for the unruptured and ruptured nodes. As shown, the peak unruptured node temperature was 21330F and the peak ruptured node temperature was 19990F. This is a reduction of 330F and 21 F, respectively, relative to BAW-10105. The majority of this difference is caused by the enhanced reflooding rates in the revised pressure distribution evaluation. | 18.4 kw/f t wcs used which is the 6-foot LOCA linit reported in BAW-10105.

As shown above, the effect of the inlet nozzle correction is compensated for by the revised system pressure drops. Since trends, i.e. core f'.ow, break flow, etc., are similar to the results presented in BAW-10105, the sensitivity studies and spectrum analyses are performed at the 6-foot elevation, the relative effects of the revised pressure distribution remains the same. | As shown above, the effect of the inlet nozzle correction is compensated for by the revised system pressure drops.

Henca, the effects of the revised system pressure distribution model would be essentially unaffected by the core elevation studied. Further, with the reduction in loop resistances core reflooding rates would be increased. | Henca, the effects of the revised system pressure distribution model would be essentially unaffected by the core elevation studied.

{{#Wiki_filter:q@ __ hq rLEL PMD EDU KFFECT ON DA'!!S-EhS9C iTIT J Tr.Ci:N : CAL SP 41JICAT;0F', The Labcoch 6 Wilcox Cenpany has evaluatcd thc thern,1-: d7 raulie Ce a;a of t:m !v.vic-Besse Nuclear Power Station Unit No. 1 and has identified thernal margins which can be used to offset the DNBR reduction uhich results from fucl rod bcuing. The rod bow versus burnup curve used for this evaluation is consistent with that given in Reference (1) and in Section 3.2 of the " Interim Safety Evaluation Report on Ef fects of Fuel Rod Bowing on Thernal :fargin Calculations for Liaht Water Reacters". The red bou versus burnup curve has been used in conjunctica uith the Uestinghouse curve of DSER reductien, versus rod bcu to deternine the reduction in DMER as a function of burnsp. In daterrd n-ing a rod bcu penalty, the following thermal cargins have been identified to help of f. e t the DNER reduction:
- 1. The flou area (pitch) reduction factor, which is used to acccunt for the reducticn in DNSR due to pitch reduction fren fabrication tolerances and initial rod bcw.
This factor has been determined to be cquivalent to a reduction of 1.3% in EM3R.
- 2. Renoval of the densificaticn pcwer spike factor from DMBR analyses. This factor has been determined to be equivalent to a reducticn of 1.1" in DN3R.
Ecced on this evaluation and t .e therral cargins prescated in (1) and (2) hove, a reduction in DNBR is required for Davis-Besse Unit Cne. The required reduction for Cycle 1 of Davis-Besse 1 has been accennodated by adjusting the Pressure-Tenperature Limits and the corresponding variable low pressure trip set point as given in Bases Figure 2.1 and Figure 2.1-1, respectively, of the Davis-Besse Unit 1 Technical Specifica-tions, and in the axial power inbalance and overpeteer limits as given in Fi ures 3 2.1_. 2.2-1 and 2.2-2 of these Technical Specificaticns. The axial peuer-imbalance envelepes , Figures 3.2-1, 3.2-2 and 3.2-3 have also been revised to cetpensate for predicted red bou pouer cpikes. Changes have also been nade in the RPS trip setpoints and allevable values listed in Table 2.2-1 of the Technical Specifications to account for instru=ent drif t in accordance with the meeting betueen NRC and TECO ef December 10, 1976.

j The QUADRAli PC'.!ER TILT limit assures that the radial ;ctier distribu-tion satisfies the desica values used in the ocwer cacabili:V analysis. Radial pcuer distributi5n measure:.an:s are mac'e during star;hp teiing i and pericdically during pcwer operation. The QUADRANT PO',!ER TILT limit at which corrective action is red'uired provides D:13 and linear heat generation rate protecticn with x-y piane power tilts. In the event tne til; is not corrected, the margin for uncertainty en Fg is reinstated by reducing the power by 2 'cercent for

The limits cn the D:13 related parameters assure that each of the parameters are maintained within the normal steady state enveloce of-operation assumed in the transient and acciden analyses. The limits are consistent with the F5AR initial assumations and have been analy:ically demonstrated adequate to maintain a minimum CNBR of 1.30 throughout each analyzed transient. The 12 hour periedic surveillance of these parameters through instru-ment readout is sufficient to ensure that the parameters are restored within their limits following load changes and other excected transient 4 operation. The 18 month pericdic measurement of the RCS total ficu rate using delta P instrumentation is adequa:e to detect ficw degradatica and ensure correlatien of the ficw indication channels with measured ficw such that the indicated percent ficw will provide sufficient verification j of flow rate on a 12 hour basis.

- 2. The cctbinatica of radiai and axial ceak tha: causes central fuel melting at tne hot spot. The limit is 20.4 kw/ft.
Power peaking is net a directly observable'cuantity and therefore limits have been estabiished on the basis of the reactor pcwer imbalance A produced by the pcwer peaking. v The specified ficu rates for curves 1, 2, and 3 cf Figure 2.1-2 correspond to the expe:ted mininua ficw rates with four pumps, nrce pumpt, and one pucp in each lo:p, respectively. The curve of Figure 2.1-1 is the cost restrictive of all possible reactor ccolant purp-caximca thernal cwer cctbina:icas shown in BASES Figure 2.1. The curves of SASES Figure 2.i represen the conditiens at which a minimun 0:iSR of 1.32 is precicted at the taxicum possible thermal pcwer for the number of reactor coolant pumps in cpera icn or the local quality at the poin: of minicua 0:;3R is equal to +225, whichever conditica is more restrictive. wer e v 4.ves u- o w m- +re-r,m_ emrs on e,n .e., a-s m am pen;ci~ ria. Using a local quality limit of +225 at the point of miniaun C::BR as a basis for curve 3 of SASES Figure 2.1 is a conservative criterion even though the cuality at the exit is higher than the quality at the point of minimum D:;SR. The D:'BR as calculated by the EL'.i-2 D iS correlatica centinually increases frca poin: of cininum D::SR, so that the exit D:;3R is alt.ays higher.

l DAVIS-BESSE-1 LOCA AilALYSIS - DESIGN PRESSURE DRCP EVALUATION
- 1. Introduction ,
The Davis-Besse-1 (DB-1) LOCA Analysis, reported in B&W topical report BAW-10105, was per formed in the winter of 1974-1975, and was based on the system pressure distribution available at that time. In comparing that evaluation to one for a nearly identical plant which utilized pressure distributions developed in 1976, an erroneous input value affecting the reverse ficw pressure drop for the ! inlet nozzle was discovered. Correction of the DB-1 model only in the area of the inlet nozzle (upgrading the nozzle model to the 1976 values) would have made it necessary to reduce the peak linear heat rate. Such a reduction is, however, inapprcpriate, in light of the availability of improved design pressure distribution models based en actual operating plant experience. Data from the i 177 FA operating plants, unavailable when the 08-1 analysis on file with the NRC was performed, has been used to alter and verify system pressure distributions. These improved distributions are the basis upon which. 'to construct the LOCA j evaluation. This paper presents the results of our revised arid improved l evaluation of the loss of coolant accident for the DB-1 plant. l The subject of conservatisms and the appropriateness of the margins in present and past calculations has been carefully considcred in this analysis. System l l pressure distribution has heretofore been based on a best estimate evaluation i using the data available. Nearly endless parameter variations would be necessary i i if conservatisms were to be placed within the pressure drop model itself. Therefore the industry and the NRC has chosen to use a best estimate approach for these inputs. B&W concurrs with this approach and has used it consistently l
i in past analyses. In order to ensure that the transient flow utilized in determining the cladding temperatures is conservative relative to the expected case, Appendix K requires that a higher than realistic discharge model (break flow model) be used with a spectrum of break sizes. All analyses performed to demonstrate compliance with the criteria of 10CFR50.46 are then based on the worst spectrum case. In this way, flow conservatism is positively assured. For B&W plants, the worst case result has always been the largest cold leg pipe break considered. Conservatism of this approach is demonstrated by comparing the worst case spectrum result (CD = 1.0) to the expected case (CD = 0.6). I i !
- For the DB-1 plant type, a double-ended cold leg break with a discharge j coefficient of 1.0 yields a peak cladding temperature 3500 F higher than the 1
l expected case, the same break with a discharge coefficient of 0.6. This l
\
difference reflects the conservatism on only transient ficw and ignores other ) known conservatisms in Appendix K. As the revised pressure drop evaluaticn does not alter the spectrum approach, the results contained here remain i suitably conservative for demonstrating compliance to 10CFR50.46. Using the revised system pressure distribution has resulted in a slight drop in the peak cladding temperature of about 300 F from the original DB-1 evaluation. The analysis also includes certain model adjustments, detailed l i later, which have been imposed by the NRC since the 08-1 original submittal ) and were therefore not considered in the original work.

- 2. Sumr.ary and Conclusions 1
The peak cladding temperatures obtained for the re-evaluation of the 08-1 6-foot LOCA Limit Analysis, based on the corrected inlet nozzle model and the revised system pressure distribution, are 2133 F for the unruptured node and 1999*F for the ruptured node. These results are 33 FU and 21 F lower, respectively, than those obtained in BAW-10105 due to the enhanced reflooding of the core. Comparisons of other dependent variable evolutions, which are presented in Section 4, show that the overall transient is very similar. Thus, the trends of the spectrum, sensitivity, and LOCA limits studies reported
<n BAW-10105 -emain valid. Since the results are less severe than t'1ose reported in BAW-10105, the resulting LOCA limits curve presented in that docunent is conservative and remains a viable base for assuring compliance to 10CFR50.46.

- 3. Basis for System Pressure Distribution Alteration The determination of system pressure drop and fica distribution is cade through use of the SAVER computer code, described in B&W topical report BAW-10072. Although detailed information can be obtained from the topical, SAVER can reasonably be described as an automated table of standard industry pressure drop models as used in the design of process flow equipment. In developing the actual distributions for use in design, a normalization to existing experimental data obtained from operating plants or from vessel model flow tests is performed. Thus, best estimate values for pressure distribution are created.
For the original DB-1 LOCA submittal, as reported in B&W tcpical report BAW-10105, operational data was not yet available and the resulting pressure distributions were therefore based exclusively on calculations. The basis for this submittal is an altered pressure distribution model which contains the influence of operating and vessel model ficw data. Figure 3-1 shows the lccations where pressure drop measurements were made during Oconee 1 hot functional testing. Using this data the OTSG and reactor vessel unrecoverable pressure drops were obtained by removing momentum, elevation, and calculated reactor coolant piping friction effects. The pressure distributions within the reactor vessel and the OTSG were then adjusted to match this data. Figure 3-2 is a gross comparison of the original distribution, BAW-10105 bases, and the present best estimate. Note that the reactor vessel pressure drop when based en hot functional test data is slightly lower than the original and that the vessel model flow test results substantiate the decrease. The difference in the OTSG pressure drop is addressed f
later in Figure 3-4. For the piping there is essentially no change. Figure 3-3 compares the reactor vessel incremental pressure drops. The original calculation, based on an older design, included a long leg U-baffle wi h a prr.ssure drop of 3.45 psi. The new calculation is based on the existing desiga which does not have a long leg U-baffle. Tie upper internals pressure drop, 17.36 psi, was adjusted to match the measured total vessel value of 53.4 psi. The value thus obtained matches that measured in the vessel model flow test within 5%. Figure 3-4 shows the incremental 0TSG pressure drops. The new values are listed beside the drawing and the original model values are in parenthesis. In the upper head, a pressure drop of 2.22 psi, was used in order to match the hot functional data, 2*.67 psi total drop. A comparisen of the old and new inlet drops of 2.22 + 0.74a and 5.9 shows a difference of almost 100%. The original drop considered the inlet as an abrupt expansion which is a much larger loss than really exists. Figure 3-5 gives a synopsis comparison between the original and present pressure drop models along with the data which percipita ed the change. The col ur.3.i labeled new forms the basis for the LOCA calctlations presented here in Section 4.2. Figure 3-6 provides a summary of the information presented ; in this section. l 1 I 3-2 l

1 1 j 4. Revised Loco Pressure Distribution Analysis i Section 3 discussed the revised loop pressure drops. As noted in that section, the new pressure drops are based on test data received from operating B&W plants, or from prototype tests such as the vessel model flow tests. These i revised pressure drops resulted in a decrease of 8.8 psi in the total system pressure drop relative to that assummed in BAW-10105. From the core outlet
~
j to the pump discharge, the overall pressure drop decreased by 14%. The 6-foot LOCA limit case reported in BAW-10105 was reanalyzed using the revised loop ,
;
pressure drops, which includes the inlet nozzle correction. The results of the l analysis are present on Table 4-1. During the first half of the transient, leak flow from the break on the vessel side, Figure 4-1, increased relative to BAN-10105. Due to the removal of the U-baffle from the LP calculation for the inlet nozzle, the resistance to flow out the break decreased and thereby resulted in the increased flow out the break. However, flow through the break on the pump side, Ftqure 4-2, also shows increased leak flow during the early stages of the transient. The break on the pump side exhibited the increased flow due to the reduction in the overall resistance from the vessel to the break on the pump side, i.e. from the top of the core through the hot leg, steam generator and across the pump j in the broken loop. While the reactor coolant pump in the broken leg is a resistance during the blowdown, at one second in the transient, it only represents i approximately 70% of the resistance from the vessel to the break on the pump side. The reduction in the pressure drop over this path reduced the overall resistance and resulted in 2% more flow out the break on the pump side. During the later stages of blowdown, leak rates for both paths were lower than that l

in BAW-10105 due to the decreased system pressure, Figure 4-3.for the revised pressure drop case. The end of blowdown occur-ed at 22.4 seconds in comparison to 24.0 seconds for the 6-foot LOCA limits case in BAW-10105. Figure 4-4 presents the hot spot core flow comparison. The effect of the i i increased flow out the break on the vessel side is compensated for by the
=
increased flow out the break on the pump side. In fact, core flow was increased for the first half of the transient. As shown in Figure 4-6, the increased 4 core ficw resulted in lower cladding temperatures for the positive core flow phase of the accident. During the negative core flow phase of the accicent, the revised loop pressure model did not cool as well as the analysis in i BAW-10105. However, the effect of the decreased cooling during the negative i core flow period was compensated by the increased cooling during the positive J core flow period and the earlier end of blowdown. At the end of blowdown, both cases predicted approximately the same cladding temperature. The REFLOOD model was modified to include the revised system pressure drops. Table 4-2 provides a comparison of the flow path resistances used in REFLOOD for this case and the BAW-10105 case. In this analysis, the additional 0.25 psi pressure drop to account for the effect of steam-water interaction due to high pressure injection was included in the cold legs. Figure 4-5 presents a ccmparison of the reflooding rates. The revised pressure distribution c- se yielded higher i flooding rates than those in BAW-10105 due to the decreased resistance from the downcomer to the break, which resulted in increased vent valve ficw, and the decreased loop resistance, which resulted in more loop flow. A THETA analysis was performed to determine the cladding temperature response. The version used included the post-CHF heat transfer logic described in the l i letter K.E. Suhrke to S.A. Varga dated 1/24/77. A peak linear heat rate of 4-2
18.4 kw/f t wcs used which is the 6-foot LOCA linit reported in BAW-10105. The results of the analysis are presented in Figures 4-6 and 4-7 for the unruptured and ruptured nodes. As shown, the peak unruptured node temperature was 21330F and the peak ruptured node temperature was 19990F. This is a reduction of 330F and 21 F, respectively, relative to BAW-10105. The majority of this difference is caused by the enhanced reflooding rates in the revised pressure distribution evaluation. As shown above, the effect of the inlet nozzle correction is compensated for by the revised system pressure drops. Since trends, i.e. core f'.ow, break flow, etc., are similar to the results presented in BAW-10105, the sensitivity studies and spectrum analyses are performed at the 6-foot elevation, the relative effects of the revised pressure distribution remains the same. For the LOCA limits, the changes in pressure distributien at any elevaticn in the core is small relative to the overall chang throughout the systam. Henca, the effects of the revised system pressure distribution model would be essentially unaffected by the core elevation studied. Further, with the reduction in loop resistances core reflooding rates would be increased. Th refore, the analysis presented in BAW-10105 is conservative and remains a valid licensing document for assuring confonaance of CB-1 to 10CFR50.46. k 4-3 l
