5. PROBABILISTIC FRACTURE-MECHANIG ANALYSIS OF POTENTIAL OVERCOOLING SEQUENCES FOR H. B. ROBINSON UNIT 2 5.1. Introduction i This chapter provides detailed information regarding the probabilistic fracture mechanics analysis of the H. B. Robinson Unit 2 (HBR-2) reactor vessel and another (hypothetical) vessel (identified as HBR-HYPO) that was included for illustrative purposes. The chapter discusses (1) the conditions necessary for failure (through-the wall cracking) of a PWR pressure vessel as a result of a PTS transient, (2) the fracture-mechanics models used for evaluating vessel integrity, and (3) the results of probabilistic fracture-mechanics ana-lyses of the two reactor vessels mentioned above. Supplementary information is included in Appendices G, H, and I.

The hypothetical vessel HBR-HYPO was created for these studies after it became apparent that the probability of failure of the HBR-2 reactor pressure vessel would be too small to permit an appropriate illustration of the methods of analysis. Values of the initial fracture toughness and of the concentrations of copper and nickel for the HBR HYPO vessel were ' adjusted upward to increase the probability of failure; otherwise the two vessels are identical. 5.2. Description of Basic Problems

 .          During a PTS transient in a pressurized-water reactor (PWR), the reactor pressure vessel is subjected to thermal shock in the sense that thermal stresses are created in the vessel wall as a result of rapid removal of heat from its inner surface. The thermal stresses are superinsposed on the pressure stresses with the result that the net stresses are positive (ten-sile) at and near the inner surface of the wall and are substantially lower and perhaps negative elsewhere, depending on the magnitude of the pressure stress. The concern over the high tensile stresses near the inner surface is that they result in high stress intensity factors (Kr) for inner-surface flaws that may be present. To compound the matter, radia-tion damage and the reduced temperature associated with the thermal shock result in rela-tively low fracture toughness values for the vessel material, particularly near the inner sur-face. Thus, there is a possibility of propagation of initially very shallow as well as deeper flaws, and the probability increases wdth time because of the time dependence of radiation damage.                                                                        -

The positive gradient in temperature and the negative gradients in stress and fluence through the wall tend to provide a mechanism for crack arrest. Even so, if the surface crack is very long and propagates deeply enough, the remaining vessel ligament will become plastic, and the vessel internal pressure will ultimately result in rupture of the vessel Thus, for each thermal transient there will be a maximum permissible pressure that is a function of the time that the vessel has been in operation.

                                                                                                                                - . =           _

s,

i; y HBR-5.2 - l Crack propagation may also be limited by a phenomenon referred to as warm prestressing  ;

(WPS), which has been demonstrated to some extent in the laboratory with small i specimens and also in a rather large, thick-walled cylinder during a thermal shock experiment.2 In such cases, WPS simply refers to the inability of a crack to initiate while K iis decreasing with time, that is, while the crack is closing. While this special situation

is encountered during some specific overcooling accidents, caution must be exercised in
. taking credit for WPS because changes in the pressure that affect little else can delay or eliminate the requisite conditions for WPS. For instance, a delay in WPS will generally {

increase the chances of crack initiation, while a reversal of Ki from negative to positive t can result in crack initiation following WPS. An evaluation of the potential for initiation under this latter condition requires knowledge of a fracture toughness value that may be substantially more than the standard measured value.' Unfortunately, sufficient data of this type are not available for inclusion in this study. The area of the vessel of particular concern lin the event of a PTS transient is the so-called i beltline region, that is, the area directly across from the core where (1) the radiation damage is the greatest, (2) the thermal shock could be severe, and (3) a rupture of the { vessel could preclude flooding of the core. Whether or not a particular degree of rupture associated with a particular transient could in fact preclude flooding of the core has not been determined but is under investigation.3 For the purpose of this report, it is sufficient to predict whether a flaw will propagate completely through the wall of the vessel. i The radiation-induced reduction in fracture toughness of the vessel material is s' function

!                                  of the fast neutron fluence and the concentrations of copper (a contaminant) and nickel (an alloying element). Furthermore, for the same values of fluence, copper and nickel,                                ,

i radiation damage tends to be greater in the welds that join the segments of the vessel than i in the segments (base material). In most PWR vessels the highest concentrations of copper are found in the welds, and many of these welds have high concentrations of nickel as well. Thus, for some PWR vessels the welds are of primary concern. However, since i the segments have a much larger surface area, they could have many more flaws, and this  ;

might offset the difference in radiation damage between segments and welds. l 2 i I

! The beltline region of reactor pressure vessels is fabricated using either forged ring ses-ments or rolled plate segments. Vessels made with forgings have only circumferential welds, while plate type vessels have both circumferential and axial welds, as shown in Fig-i ure 5.1. Thus, within the beltline region of a plate type vessel there are three basic subregions to consider: axial welds, circumferential welds and plate segments. i I For flaw depths greater than --20% of the wall thicliness, axial flaws have significantly greater values of Ki than circumferential flaws. Thus, other things being equal, axial j flaws in the plate segments and in the axial welds of plate. type vessels are of greater con- ! cern than c' 'umferential flaws. Of course, differences in chemistry, fluence and initial i fracture toughness could reverse that situation. ' i e T _,. ._._._ _ ______ _ _ _ _. _ _ , T _ ._ .- .____._._,__n

        ,     For plate type vessels with staggered axial welds and for which radiation damage is much more severe in the welds than in the base material, the final surface length of a propagat-
ing inner-surface axial flaw in an axial weld tends to be limited to the length of the axial I
weld in which it resides, that is, the height of the shell course. Furthermore, only that por.  :

tion of a weld that is within the axial bounds of the core need be considered because of the steep attenuation of the fast-neutron flux, and thus the radiation damage, beyond the fuel region. , i If the chemistry in adjacent plate segments is about the same, the extended surface length

of an axially oriented flaw in a plate segment is also limited by the height of the core but not by the height of a shell course. Thus, the surface length of axial welds in plate seg-
ments can be much greater than those in axial welds.

1 i Because of an azimuthal variation in the fast-neutron flux (see Figure 5.1) and ps:ibly 1 in the material chemistry, the extended length of an initially short, circumferentially oriented flaw located in a circumferential weld or in a plate segment also tends to be lim-i ited.  ; The behavior of an assumed flaw can be predicted for a given transient by using fracture- ! ~ mechanics methods of analysis. In such an analysis the parameters and considerations

;            involved are the size, shape, and orientation of the flaw; the thermal and pressure stresses resulting from a specific transient; the temperature and fast neutron fluence distributions throughout the vessel wall; the effect of fluence and material chemistry on radiation                         i damage; a variety of material properties; and a comparison of the stress intensity factor
(Kg) associated with the tip of the flaw with the material's static crack initiation and

! crack arrest fracture toughness values (K, i and Kr.). Each of these factors must be con-sidered in the development of an appropriate analytical model for evaluating the integrity

of a PWR vessel when subjected to PTS loading conditions. The necessary models for per-forming a probabilistic fracture-mechanics analysis for a PWR reactor pressure vessel and i the results of the analyses for the HBR 2 and HBR HYPO vessels are discussed in the remainder of this chapter, b ,

! 5.3. Calculational Models I The conditional probability of vessel failure (through the wall cracking) was calculated for i the HBR 2 and HBR HYPO reactor pressure vessels with the OCA P code, a fracture- ! mechanics code developed at ORNL for application to pressure vessels.' OCA P accepts i as input the primary' system pressure, the temperature of the coolant in the reactor vessel i downcomer, and the fluid film heat transfer coefficient adjacent to the vessel wall, all as a

function of time in a specified PTS transient. The code then performs one dimensional

, thermal and stress analyses for the vessel wall and finally a probabilistic fracture-

;           mechanics analysis. Details of OCA P necessary for an understanding of the vessel ana-
lyses included herein are discussed below.

5.3.1. Fracture-Mechanics Model I l 5.3.1.1. Basic approach The fracture-mechanics (FM) model in OCA P is based on linear clastic fracture mechan-ics (LEFM) and uses a specified maximum value of Kr, to account for upper-shelf behavior. The stress intensity factor (Kr) is calculated by using superposition techniques "in conjunction with influence coefficients calculated by finite element techniques. , The application of this procedure makes it possible to perform a large number of deterministic FM calculations at reasonable cost, a necessary condition for performing the probabilistic

analysis.

5.3.1.2. Speelfic finws laeluded The HBR-2 vessel was fabricated from sections of plate and has both axial and circum-ferential welds in the beltline region, as shown in Figures 5.2 and 5.3. The HBR. HYPO vessel was assumed to have the same configuration. For both configurations the length of flaws in the axial welds with depths greater than ~2 in, was assumed to be approximately the height of the intermediate shell course, and the shape was assumed to be semielliptical (this flaw is referred to as the 2.m flaw). Since the ends of this flaw are fixed, propaga-tion was judged on the basis of the K ratios (Kg/Krc, K /Kr.) at the deepest ends of this type of flaw Deep axial Haws in the plate region were assumed to be two-dimensional (to have infinite length) since their surface length could extend the full length of the core, and de~ep circumferential Daws were also assumed to be two-dimensional. Shallower flaws also were assumed to be two-dimensional, because long shallow flaws are essentially two-dimensional, and short flaws tend to grow on the surface to become long Haws,8 at least in the absence of cladding. Because the effect of cladding on the surface extension of short flaws is not known at this time, any possible beneficial effect it may have has been discounted. 5.3.1.3. Claddlag As just noted, the effect of cladding on the surface extension of finite. length flaws was not considered. However, cladding on the inner surface of PWR pressure vessels was included in the OCA.P analysis as a discrete region to the extent that the thermal and stress effects were accounted for. Because of the difference in the coefficient of thermal expansion between the cladding and base material, the calculated stresses in the cladding exceed the yield strength of the clad. ding by an appreciable amount, and this results in an overestimation of the Kg values for the Daws, which were assumed to terminate in the cladding or extend through the cladding into the base material. An alternative approach would be to limit the stress in the clad. ding to the yield stress, but this underestimates Kg because Kg is sensitive to the strain, which is not limited by the yielding phenomenon. The difference in Kg between these two extremes is not large; thus the conservative extreme was selected.

Kr. = 1.43 {33.2 + 2.806 exp[0.0200 (T - RTNDT + 100)]}, ksi 6 ,(5.1)

Kr. = 1.25 {26.8 + 1.223 exp(0.0145 (T - RTNDT + 160)]}, ksi 8 ,(5.2) where the quantity in braces represents the ASME Section X1' lower bound toughness value, and T is the temperature at the tip of the flaw (in *F). These expressions were obtained by letting the ASME lower bound curves rep _ resent the mean values _minus two

,          standard deviations (2a) and by letting a(Kr.) = 0.15 Kr.and a(K.)                                                 i = 0.10 Kg..

I In many cases, if crack arrest takes place, it must do so at upper shelf temperatures, that

is, at temperatures that, under static loading conditions, result in ductile rather than brittle behavior of the material. Crack arrest under these conditions is act well understood but has been included in an approximate manner by specifying a maximum value of Kr. that corresponds to the upper portion of an upper shelf tearing resistance curye. As illustrated .

j in Figure 5.4, which is a plot of K vs crack depth (a) and temperature (T) at a specific ! time in a transient, if the load line (Kg vs a, T) latersects the Kr. curve at K. i < (Kr.),,,,, upper shelf temperatures are not encountered. If, on the other hand, the load } line misses the rising portion of the Kr. curve and then decreases, as it does for some tran-sients, there is, according to the model, a possibility of crack arrest at upper shelf tempera- ) tures. i The tearing resistanes curve selected for this study represents a specific high copper, low. upper. shelf weld material that had been irradiated to a fluence of ~1.2 X 10 " 2 l neutrons /cm at a temperature of ~550*F and tested at 390*F.7 The upper, nearly flat 1 portion of this curve corresponds to a fK value of ~200 ksi E, and this value was used I for (Kr.),u; K was f obtained using the relation I Kf=M, (5.3) ) where 4

HBR-5.11 The attenuation of the fluence through the well of the vessel is approximated with F = Fo e ** , - (5.7) where Fo is the fluence at the inner surface of the vessel and a is the crack depth in inches. The specific value of the coefficient in the exponent accounts to some extent for the effect of space wise spectral changes on radiation damage.: If the assumption is made that a short and shallow surface flaw can extend on the surface through the cladding to become a long flaw (and this assumption is made for these stu-dies), then it must be assumed that under the proper circumstances a very shallow flaw that initially resides entirely within the cladding can propagate radially. Unfortunately, the fracture toughness properties of the cladding material are very uncertain and are known to be dependent on the cladding application process; however, the few experimental data that are availab!c indicate that the radiation induced reduction in fracture toughness can be similar to that for the base material. As an expediency, which may or may not be conservative, it was assumed that the cladding has the same fracture-toughness properties as the base material (Eqs. (5.1), (5.2), (5.5) and (5.6)]. In the OCA P analysis, assump-

    .       tions regarding the fracture behavior of the cladding influence only the laitiation of very shallow flaws that initially terminate in the cladding.                                       Under some circumstances, including the above assumption regarding the fracture toughness of the cladding, these shallow flaws will initiate and result in vessel failure. Therefore, it was necessary to include the fracture properties of the cladding.

5.3.1.5. Warm , 4 '; As mentioned in Section 5.2, crack initiation cannot take place while Kg < 0. However, if, following a period of K < 0, K once i again increases with time, crack initiation can take place, but the critical value of K may be substantially more than the standard meas-ured value (K.). i This latter situatica leads to one of two problems associated with the , inclusion of WPS in the fracture mechanics model; appropriate fracture toughness data are i not yet available. The other problem is more specific to this particular study. The rela-tively few transients for which detailed fracture mechanics calculations are made represent categories of transients for which the pressure histories are not necessarily well deflaed, and, as indicated in Section 5.2, variations in the pressure history can prevent or delpy WPS. For these reasons it was not considered prudent to include the effects of WPS in the basic study. However, the possible effect of WPS was evaluated for the dominant transients to the extent of not allowing crack initiation while Ki < 0, provided, following this period, K idid not exce'ed the previous value of (K ) . l. i l

M 7lx=sy . HBR-5.12 _ 5.3.1.6. Flaw behavior depicted with critical-erack-depth plots The deterministic fracture-mechanics model described above is used in OCA P to predict the behavior of a Daw during a specified PTS transient at a specified time in the life of the vessel, and the calculated behavior can be illustrated with a set of critical-crack depth curves similar to those shown in Figure 5.5. This figure consists of a plot of crack depths corresponding to various events and conditions as a function of the time in the transient at which the events or conditions take place or exist. Figurer 5.5 includes (for 2.D, axially oriented Daws only) the locus of points for Ki = Kr. (crack-initiation curve), Ki = Kr. (crack arrest curve), Ki = (Kg). (warm prestress curve withi K = 0), and Kr " constant (iso Ki curves). For times less than those indicated by the WPS curve, crack ini-tiation will take place, but for greater times initiation will not take place unless perhaps there is a perturbation in Kg that negates the requisite conditions for WPS. The dashed lines in Figure 5.5 indicate the behavior of two initially shallow flaws, ignor-

   .      ing the effects of WPS. The deeper flaw would initiate at a time of 42 min into the tran-sient and would extend through the wall without arresting. The other flaw would initiate at an earlier time, would arrest at a point 36% of the way through the wall, and then would reinitiate at a time of --88 min and penetrate the wall Earlier in the life of the vessel the tendency for complete penetration of the wall is less.
 .        5.3.1.7. ATNDT as the '":;:t variable                        -

For the probabilistic fracture mechanics analysis (see Section 5.3.4), it is convenient to let RTNDT, be the independent variable rather than Cu, Ni, Fo and RTNDTo. This can be accomplished by ignoring Eq. (5.6) and combining Eqs. (5.5) and (5.7) to obtain ARTNDT(a) = ARTNDT, e*S* , ($.8) where - ARTNDT, = ARTNDT at inner surface, ARTNDT(a) . = ARTNDT at tip of naw, a = depth of Daw, in. This relation, in combination with Eq. (5.4), can be used directly in Eqs. (5.1) and (5.2) without having to specify Cu, Ni and Fo. However, when RTNDT, is being calcu-lated for a specific reactor vessel for comparison with results of a probabilistic analysis that uses RTNDT, as the independent variable, only Eq. (5.5) should be used so as to maintain consistency. Furthermore, the results of the fracture. mechanics analysis are somewhat sensitive to the value of RTNDTo and for additional reasons can be significantly different than those obtained using Cu, Ni, and To and RTNDTo as independent variables (see Appendix G). l

  • j When the superposition technique is used in combination with influence coefficients to cal-i culate Kg, the stresses required are those at the crack plane in the absence of the crack l

and with no variation in the direction of the length of the crack. For the analyses dis-cussed herein, it was assumed that there was no azimuthal variation as well, and thus the one-dimensional stress analysis model incorporated in OCA-P was adequate. Material properties required for the stress analysis included the coefficient of thermal expansion (a), Young's modulus (E), and Poisson's ratio (r). Although these properties have some temperature dependence, it was determined' that the use of appropriate average values results in an error in the calculated value of Kg of less than 10% Thus, average values were used based on the data in Ref.10. The values used are as follows: Property Base Msterial Cladding lii, 'F~ l 8.0 X 10-' 9.9 X 10-8 f, kai 2.8 X 10 8 2.7 X 10 4 ! T 0.30 0.30 j 5.3.3. Dermal-Analysis Model . l' Temperatures in the wall of the vessel are required for two purposes: to calculate the frac. ture toughness and to calculate the thermal stresses. The temperatures required for deter-mining the fracture toughness are those in the plane of the flaw, while those used in the 1 one dimensional analysis of the thermal stresses must represent some type of average dis-tribution through the wall. The thermal stresses in the vicinity of the crack plane are more sensitive to the radial temperature distribution at the crack plane than elsewhere.

Since these temperatures are the same a those needed for the fracture toughness determi-4 nations, and since only one set of temperatures was to be used for both the stress and toughness calculations, the local temperatures would be the choice. These particular tem.

peratures were not available, but fortunately the results of the thermal hydraulic analysis indicated that for the transients of laterest there was not much azimuthal variation in the ! downcomer coolant temperature. Thus, the time dependent temperature distributions in i the wall of the vessel were calculated with the one-dimensional thermal analysis model in ' OCA P, using average downcomer coolant temperatures and heat transfer coefficients. l Material properties required for the thermal analysis include the thermal conductivity (k), j specific heat (c,), and density (p) of the vessel material.

5.3.4. Prah=hikele-Amelysis Model 5 The OCA-P probabilistic model, which is similar to that developed by Gamble and Strosnider," is based on Monte Carlo techniques; that is, a large number of vessels is gen-ersted, and each vessel is then subjected to a fracture-mechanics analysis to determine whether the vessel will fail. Each vessel is defined by randomly selected values of several parameters that are judged to have significant uncertainties associated with them. The ] calculated probability of vessel failure is simply the number of vessels that fait divided by the total number of vessels generated. It constitutes a conditional probability of failure,  ! P(FlE'), because the assumption is made that the PTS transient (event) taxes place. A logic diagram summarizing the various steps in the OCA-P probabilistic analysis is shown in Figure 5.6. 1 i l The parameters simulated for the analyses discussed herein are crack depth (a), RTNDT, K.,i and K i Normal distributions were assumed for each of these parameters except the i crack depth; the standard deviations and truncation values used in the analysis are i included in Table 5.1. When RTNDT, is used as the independent variable (see Section 5.3.1.7), it is necessary to . account for the distribution in ARTNDT due to the distributions in Cu, Ni and Fo. As , , discussed in Appendix G, the distribution in ARTNDT is dependent on the mean values l of Cu, Ni and Fo, and an ' average

  • normal distribution was used with the standard devia-l tion given in Table 5.1.

i The advantage in using RTNDT, as the independent variable in the probabilistic fracture-i mechanics analysis is'that a normalized value of P(FlE), referred to as 8, vs RTNDT, ! can be determined for the different flaw types (infinite and finite-length axial and circum. i . forential flaws) for all of the transients of interest, independent of specific values of Cu, Ni l and Fo. Once these curves are available, they can be used for any reasonable set of Cu, j Ni,and Fo values, thus allowing a determination of P(FlE) for more than one vessel without a detailed analysis, provided that the same transients are appropriate for both

vossals. It is only necessary to (1) calculate RTNDT, for each region of interest (defined
ecific values of Cu, Ni, Fo, and RTNDTo) using Eqs. (5.4) and (5.5); (2) deter-by sp% from the 8 vs RTNDT, curves; and (3) determine P(FlE) from mine

The probability of having a flaw in n specific region with a depth in a specific range of crack depths Aa,is given by 1 P(Aaf) - NV f f(a)B(a)da , (5.10) 4 1 where N = number of flaws of all depths per unit volume of a specific region, V = volume of the specific region, fa) = flaw-depth density function, B(a) = probability of nondetection. The parameters N and fa) pertain to vessel conditions prior to preservice inspection and , repair, and B(a) is derived on the basis of repairing or otherwise disposing of all detected flaws. The value of N and the functions fa) and B(a) are not well known because most of the available inspection data do not pertain to surface flaws that extend into and through the cladding of a PWR pressure vessel. For the analyses dLe_M herein, the functions fa) and B(a) were those suggested in the Marshall report:2 and are as follows: f(a) = 4.1 e-4 l* , (5.11) , B(a) = 0.005 + 0.995 ,-2. 7' , (5.12) l where a = crack depth, in., ao

                                     =              1.

fAa)da o For the HBR 2 vessel the probability of ncodetection, B(a), should probably be set equal to unity, independent of a, because the relistility of inspections for flaws in and extending a short distance beyond the cladding has not been quantified. Furthermore, it is not likely that any detected flaws of this type were repaired. Even so, Eq. (5.1) was used in the analysis of the HBR 2 and HBR HYPO. If B(a) = 1 were used instead, P(11E) would be about twice as much. Thus, the results of this study can be interpreted accordingly. 3 The value of N used in these studies was 0.03 flaw /ft 3 (I flaw /m ) of weld and base , material, and it was assumed that all flaws were inner surface flaws normal to the surface. Flaws in welds were oriented in the length direction of the weld, while those in the plate segments were oriented axially. The assumed value of the flaw density agrees with that suggested in the Marshall report,12 but the uncertainty is considered to be ver g (values of N corresponding to la variations are estimated to be 3 and X 310~* y lar' e 3 flaws /ft ).

As mentioned above, the calculated probability of vessel failure for this study is the number of simulated vessels calculated to fail divided by the total number of vessels simu-lated or otherwise accounted for. Thus, N g3,g3) P(PlE) = " h VN j f f(a)B(a)da , j o - - - where 9, "',.' N j , Nfj. = number of vessels with a flaw in the jth region that fail, N,j = number of vessels simulated with a flaw in the jth region, Vj = volume of jth region. The integral in Eq. (5.13) accounts for the vessels that have no flaws whatsoever, and each term in Eq. (5.13) represents the contribution to P(F(E) of each specified region of the vessel. For very small values of P(FlE) , the values of N,j required to achieve reasonable accu-racy becomes quite large. Under some circumstances the value of N,j can be reduced by using importance sampling techniques. This was done in some cases by eliminating flaw depths that did not contribute significantly to initiation and by sampling only the tails of , the RTNDT and ARTNDT distribution functions. In each of these cases the portion of the distribution function not sampled is accounted for by multiplying the number of simu-lated vessels, N,j, by a correction factor. Equation (5.13) then becomes

Table 5.2 gives the corresponding values of F2         -

and F3 as a function of the point on the distribution curve at which sampling is com-a menced. As indicated, if the distribution is sampled above Ia, F = 6, and if it is sam-pied above 2a, F = 46. If both ARTNDT and RTNDT are sampled only above 1.25a, and if the first crack-depth increment can be omitted, Fi XF X F 3= 300, which l represents a significant savings in computer costs for the same accuracy in P(FlE). Of course this type of importance sampling can only be used when the first crack depth incre-l ment does not contribute much to P(FIE), and when P(PlE) is small enough that only the tails of the ARTNDT and RTNDT distribution functions contribute significantly to l P(FlE). i' After the specified ~ number of vessels has been simulated, a deterministic analysis is made for each vessel to determine if failure will occur during a particular transient at a specified time in the life of the plant. The criterion by which failure is judged is as follows: if, fol-l lowing an initiation event, Ki remains greater than Kr. up to or beyond the point at which i plastic instability occurs in the remaining ligament, failu're is assumed. The onset of plas-

tic instability is evaluated oa the basis of achieving an average pressure stress in the j remaining ligament equal to the flow stress. The flow stress is assumed to be independent i of temperature and fluence and is specirmd as 80 ksi, i

l The number of vessels that must be simulated depends upon the accuracy required for the l calculated value of P(FIE), and as small a number as practical is used to minimize com. puter costs. The minimum number of simulated vessels required to satisfy a specified l accuracy is estimated by applying the central limit theorem.'3 Using this approach and j specifying a 95% confidence level yields (5.16) P(FlE)j = P) NV j f f(a)R(a)da i 1.96 aj , , o I 1. 4 1 t j l l_ ._. n.

y.s, . g, , HBR-5.23 It is of interest to note (Eq. 5.21) that the error for a single region, ej, is only a function of Nfj. According to Refs.14 and 15, for the estimate of ej to be reasonably accurate, Nfjshould be greater than 5 (Ref.14) or 9 (Ref.15). However, when the total error

     ,          is calculated (Eq. 5.22), this rule needs to be adhered to strictly only for those regions that contribute significantly to P(ElE) .

In order to keep computer costs within reasonable bounds for the PTS studies, the permis-sible error in 'Pj was allowed to increase with decreasing f), and in general, as shown in { Figure 5.7, larger errors were permitted for the nondominant transients than for the dom- 1 inant transients. The value of N,'j and the extent of importance sampling were selected so as to satisfy these criteria. An exception was in the sensitivity analysis since, in some cases, better accuracy was required. 5.4. Flaw-Related Data for the HBR-2 and HBR-HYPO Pressure Vessels As has already been mentioned (Sections 5.2 and 5.3.1), the areas of the vessel of particu-lar concern with' regard to flaw propagation are those in the beltline region and include the plate segments and the axial and circumferential welds. Fracture-mechanics data fer these regions are included in Table 5.3 for HBR-2 and in Table 5.4 for HBR-HYPO. A companson of these two tables shows that the only difference between HBR-2 and HBR-HYPO are the values of Cu, Ni and RTNDTo. Values of these parameters for HBR- . HYPO were adjusted in a convenient and reasonable way so that at 32 EFPY, RTNDT, = 221*F for the region that contributed the most to P(FlE) (this corresponds , to RTNDT(2a) = 270*F]. The plate regions in Tables 5.3 and 5.4, for which only axially oriented flaws were con-sidered, could have been divided further to take advantage of the azimuthal variation in fluence. However, it appeared, at least for HBR-HYPO, that the plate region contribu-

                                                                               ~

tion to P(ElE) would be small; thus, further refinement was not warranted.

            " Much of the data in Tables 5.3 and 5.4 was taken. from Refs.16,17 and 18; values listed for Cu, Ni, Foand RTNDTo were considered to be mean values.

5.5. Results of Analysis Probabilistic fracture-mechanics analyses were performed for HBR-2 and HBR-HYPO to i determine (1) P(FlE) = f(RTNDT,) and P(FlE) at 32 EFPY for a number of HBR-2 transients, (2) the sensitivity of P(EiE) to small changes in the mean values of certain parameters, (3) the effect of including warm prestressing, and (4) the effect on l P(FlE) of certain proposed remedial measures. The results of these efforts are presented below. [ 1 i l t y--

HBR-5.27 i 5.5.1. Calculation of Conditional Probability of Vessel Failure, P(FlE) The specific transients considered for a detailed OCA-P analysis are described in Chapter 3. These transients were divided into two categcries: (1) those with final coolant temperatures >300'F and (2) those with final coolant temperatures 4300*F. Bounding-type calculations were made for the first category because the approach was much,less expensive and because it was expected that the contribution of this category to the through-the-wall crack frequencies would be negligible. Transients for the bounding calculations were characterized by a constant pressure of 2.5 ksi, a step change in coolant temperature and a fluid film heat-transfer coefficient of 400 Btu /hr ft2.*F. The results of these bounding calculations are shown in Figure 5.8. -- All of the transients in the first category and the corresponding estimates of P(FlE) at 32 EFPY are listed in Table 6.1 of Chapter 6 for HBR HYPO. Values of P(FlE) are not given for HBR-2 because they are much lower than those for HBR-HYPO and thus even more difficult to estimate. None of the transients in the first category contri-buted significantly to the"through-the wall crack frequencies for either HBR-2 or HBR-HYPO. All of the transients in the second category and the corresponding estimated values of P(FlE) at 32 EFPY are also listed in Table 6.1, for both HBR-2 and HBR-HYPO, and those with significantly high values of P(ElE) and/or through-the wall crack fre-quencies are listed in Table 5.5. Values of P(FlE) in Table 5.5 include the contributions from all of the vessel beltline regions listed in Table 5.4. For HBR-HYPO the contribution of the circumferential welds and of the plate segments was relatively small. However, because of the rather low values of Cu, Ni and RTNDTo for the HBR-2 welds, the plate regions were the dominant contributor to P(FlE) for HBR-2, and the corresponding estimates values of h were quite low (<10-6). Furthermore, and as a consequence of these low values, the estimates of the through-the-wall crack frequencies for HBR-2 are quite low (<10-H). Therefore, values of P(FlE) for HBR-2 were estimated for only a few of the transients in Table 5.5. The particular transients selected were the six that contributed the most to the through-the-wall crack frequencies for HBR-HYPO. Summaries of more detailed results for the six dominant transients at 32 EFPY are presented in digital form in Tables 5.6-5.11, and similar summary sheets are included in Appendix I for all of the transients calculated.* Each summary sheet includes the data for a variety of histographs, and a set of four histograms for transient No. 22B is shown in Figures 5.9-5.12. [ lt should be noted that only she summary sheets for the *B* cases are included in Appendix I for those j sequences involving *A* and 'B' cases. l l l

HBR-5.40 B.  ! I Appendix I'also includes for each transient calculated (1) a definition of the transient  ; 4 input to OCA.P (downcomer coolant temperature vs time, primary system pressure vs

time, and fluid-film heat transfer coefficient at the vessel inner surface vs time);

(2) curves of k f(a)Bla)da vs RTNDT,; (3) temperature distributions in the wall; o s 1 (4) curves of Kg vs t for different crack depths; arid (5) a set of critical-crack-depth curves for weld 2-273A based on 32 EFPY and mean values of all parameters except Kic, Kr., and ARTNDT which are -2a values. Examples of thede graphical outputs are shown in Figures 4.13-5.18 for transient No. 22B. 5.5.2. Sensitivity Analysis of P(FlE) i The sensitivity analysis was conducted by determining the change in P(FlE) correspond-ing to a change in the mean value of each of several parameters. The mean value of only one parameter was changed at a time, while all other parameters retained their original mean values. The parameters changed were Ki c, Kr., RTNDT, Cu, Fo, the fluid. film heat transfer coefficient (h), the downcomer coolant temperature (T,), the primary system pres- , sure (p), and the flaw density (N). The amount of the change for Kr., Kra, RTNDT, Cu, Fo, and N was one standard deviation, and the change for the other parameters was some-i what arbitrary. The sign of the change for all parameters was such that an increase in

P(FlE) murred.
  • l The values of a used in the sensitivity analysis for Krc, Kr., RTNDT, Cu, and Fo are listed in Table '5.1, and the value of the flaw density, N, corresponding to the application of 2
                  ,la was 10 times the original mean value. The change included in the sensitivity analysis for the downcomer coolant temperature consisted of a linear change in tempera-ture from zero at time zero to 50*F at a time corresponding to the minimum point in the temperature vs time curve. From then on, the change in temperature was a constant value of 50*F. The change in the heat transfer coefficient, h, was 0.25 h, and for the pressure it was 50 psi.

J The results of the sensitivity study are presented in Table 5.12 for 32 EFPY. Table 5.12 includes (1) the values of P(FlE)o, the original mean values of P(FlE), and (2) the ratio R(FlE)i/P(FlE)o, where P(FlE)g is the increased value of P(FlE)odue to a change in a simulated parameter. It is of interest to note that the sensitivities are dependent on the transients, and that P(FlE) is most sensitive to the uncertainty in N and is least sensitive to the uncertainty in the arrest toughness and the heat transfer coefficient. h

, HBR-5.48 *4 4 . 1 5.5.3. Calculation of Effect on P(FlE) of' Including Warm Prestressing la Analysis During many of the postulated PT'S transients, the stress intensity factor Kg for all crack depths first increases with time, reaches a maximum, and then decreases. For the shallow flaws that are generally responsible for the initial crack initiation event, once K tbegins to decrease it does so throughout the remainder of the transient. This time-dependent behavior of Ki may prevent failure of a vessel because a flaw cannot initiate while Kr is i decreasing, even though Kr/Ki c > 1. As mentioned earlier, this phenomenon is referred

,                to as warm prestressing (WPS), and the time of incipient WPS is the time at which X i

becomes equal to zero. For most of the HBR-2 postulated transients, WPS could be a factor because the calcula-tions indicate that for these transients,K does not become equal to Kre until after the time of incipient WPS. A typical case is illustrated in Figure 5.5. The reason for not includ-ing WPS in most of the calculations is that the K ivs t curves for the shallow flaws are i very flat, making it difficult to determine where the maximum is. Furthermore, unfore-seen variations in pressure and coolant temperature might exist and defeat WPS. Even so, it is of interest to see what the effect is for the idealized transients, and the results of such a study are presented in Table 5.13. For some transients, there can be more than one time during the transient at which j Ki = 0. For these transients, the time selected for incipient WPS was that correspond . ing to the maximum value of Kr. l . Table 5.13 shows, for each of the transients considered, the time of incipient WPS, the j calculated values of P(FlE) without WPS included in the analysis, and the ratio of i P(FjE) with and without WPS included. It is apparent that for these idealized transients the benefit of WPS can be large but is dependent on the transient.

5.5.4. Calculation of Effect on P(FlE) of Proposed Remedial Measures l' The proposed remedial measures considered in the fracture mechanics studies were (1) reduction in the fluence rate and (2) annealing of the pressure vessel.

1 5.5.4.1. Reduction is fluence rate The reduction in fluence rate was assumed to take place on January 1,1985, and it was assumed to be the same at all critical locations in the vessel wall. The effect was simply to change the proportionality constant between Fo and EFPY beyond January 1,1985. At this time the vessel will have been in service for 8.1 EFPY, and the fluence for the con-trolling region, weld 2-273A, will be 1.2 X 10 neutrons /cm .2 The fluence rate beyond 8 EFPY for weld 2 273A was assumed to be constant and equal to 0.0817 X 10/f,

,                where f is a factor by which the fluence rate can be changed. Thus, I

 .the six most dominant transients, using f = 2, 4, and 8. The results are presented in Tabic 5.14.                                                                       i i

Annealing of the pressure vessel Annealing of the pressure vessel will increase the fracture toughness of the vessel material, and the amount of the increase will depend on the annealing temperature and time, the chemistry of the material, and the number of times the vessel is annealed. Test results from small specimens indicate that essentially full recovery of the initial fracture toughness might be achieved by annealing in the temperature range 750-850*F for ~200 h.38 Although preliminary studies indicate that such a process would probably be feasible in some PWR plants, the feasibility of annealing the HBR-2 reactor vessel under these condi-tions has not been established. Nevertheless, for the purpose of this study it was. assumed that the HBR-HYPO vessel would be annealed when the plant achieved ~9 EFPY

(~ January 1986), and that there would be complete recovery of fra.:ture toughness. In effect, after annealing at 9 y, the fluence at 9 y would be zero. Thus, after 9 y, Fo X 10-l'(weld 2-273A) = 0.081'7(t - 9) , (5.24) where i i t = total time of service, EFPY. This fluence (or the corresponding value of RTNDT,) can be used to obtain values of P(FlE) after annealing. The benefit at 32 EFPY of this assumed annealing situation is j indicated in Table 5.14. l l I -

This is because it allows one to apply the results to other reactor vessels, provided the tra'nsients analyzed are appropriate for the other vessels. However, since RTNDT = RTBDTo + ARTNDT and ARTNDT = f(Fo, Cu, Ni), RTNDT is not actually an independent variable; that is, the actual independent variables are RTNDTo, Fo, Cu a-d Ni and were used as such in two related studies.242: As discussed in Sect. 5.3.1.7, for this particular study, values of Pj were obtained as a function of RTNDT,, and in doing so both RTNDTo and ARTNDT, were simulated, but only a single value of RTNDTo was considered (0*F).

This appendix discusses the derivation of the distribution function for ARTNDT and the error in using R TNDT, as the independent variable. The distribution function for RTNDT, was obtained by performing a Monte Carlo

,             analysis with Eq. (5.5), in which case Fo and Cu were simulated and different values of Fo, Cu and Ni were included. As in the two previ_ous studies,2a2 it was assumed that Fo and Cu had normal distributions with la = 0.3 Fo and 0.025 wt%, respectively. Based on this analysis, a normal distribution with la = 0.14 ARTNDT was selected for A R T N D T,.

The specific Monte Carlo cases calculated to obtain the typical distribution for ARTNDT are shown in Table G.1, and a typical histogram is presented in Figure G.I. It is , apparent that (1) the distributions are essentially normal, although the tails are not well defined, (2) the sensitivity of a to Fo and Ni is very small, and (3) the sensitivity to Cu is perhaps significant, although the extent to which it is significant depends on the sensi-tivity of P(FlE) to the distribution function for ARTNDT. Rather than investigate this latter sensitivity directly, two sets of calculations were made to ) obtain P(FlE) vs Cu for several HBR-2 postulated transients (8.6, 9.19B, 9.33, 9.41). For one set, ARTNDT, was used as an independent variable, and for the other set, Fo, Cu and Ni were used as independent variables. The results, shown in Figure G.2, indi-cate that the error in using ARTNDT, as an independent variable is (1) dependent on the transient, (2) positive for Cu > 0.25 and negative for Cu < 0.25 (the value of a used for ARTNDT was based on Cu == 0.25), (3) larger for the less severe transients, and (4) substantial (factors of --25 and 7) for the least severe dominant transient and the two extreme values of Cu considered (0.15 and 0.35, respectively). It is of interest to note that the error associated with using ARTNDT, as an independent i variable is not only the result of having to approximate the distribution function. This can I be illustrated by calculating P(FlE) for different combinations of Fo, Cu and Ni that result in the same value of ARTNDT,. Table G.2 shows the results of a comparison analysis in which Fo and Cu were simulated. two values of Cu were considered (0.2 and 0.35), and Fo and Ni were adjusted so that ARTNDT, was the same for both values of I Cu. As indicated, the lower value of Cu resulted in a higher value of P(FlE), and the i

  .           less severe the transient the greater the ratio.                                                      l

HBR-G.8 /, ' f' . The additional error introduced by variations in RTNDTo when using RTNDT as an independent variable was examined in a similar manner, that is, by comparing values of P(FlE) corresponding to different values of RTNDTo. Three values of RTNDTo were considerd (-56, 0, +56*F), and values of P(F[E) corres6onding to the two extremes were compared with that corresponding to 0*F, since RTNDTo = 0'F was used to obtain the Fj vs RTNDT, curves in this report (Appendix I). The results of the,compar-ison, shown in Figure G.3, indicate that (1) the error is positive for RTNDTo < O'F and is negative for RTNDTo > O'F, (2) it increases with decreasing RTNDT, and is small for RTNDT, > 200*F, and (3) the error is greater for the less severe transients. Although it is convenient to use RTNDT, as an independent variable, it is aprjarent from the preceding discussion that the error in doing so can be substantial. Thus, one must use the f jvs RTNDT, curves in Appendix I with this understanding. For the most accu-rate results, RTNDTo, Fo, Cu, and Ni should be used as independent variables in a

~ HBR H.3 W Appendix H - IMPORTANCE SAMPLING METHODS IN THE OCA-P PROBABILISTIC FRACTURE-MECHANICi ANALYSIS To be abic to calculate low probabilities of failure with acceptable accuracy and reasonable computer time, importance sampling was applied to three simulated parameters: crack - depth, MTNDT, and RTNDT. For each of these parameters it was first demonstrated for a specific transient that a portion of the distribution function contributed little to the probability of failure. This portion was then omitted from a subsequent simulation, but was accounted for in the number of trials by multiplying N'j, by a correction factor, as indicated by Eq. (5.14). For the crack depth distribution, only the first flaw denth w s not simulated, and the corresponding correction factor is given by I

                                                                                  =                                   -'
,                                                                                                                                                                           (H.1)
                        .                                           Fj= i         ff(a)A(a)da                             = 3.24 .

Ami The use of this acceleration method is indicated on the summary sheet in Appendix I by IACCEL = 1. ) In the case of MTNDT and RTNDT, a continuous sampling of the distribution can be i replaced by a stratified sampling of the " positive" tail. For these studies, MTNDT and

  • RTNDT were assumed to have normal distributions, and sampling was allowed to begin at 1.0 to 2.5 standard deviations above the mean, in increments of 0.25. Use of this method .

i for MTNDT is indicated on the summary sheet in Appendix ! by NDLRS = n, where n indicates the start of sampling as given in Table H.l. The variable NRTRS operates in a similar way for the RTNDT distribution. The correction factors, F j and F3j, corresponding to MTNDT and RTNDT, are given in Table H.1 and are based on a not. mal (0,1) distribution truncated at 13a. The normal (0,1) distribution, truncated at 13a, was used to establish a distribution for the strata between la and 3a for MTNDT and RTNDT,. A justification follows: Let ze normal (g,,2), p - 3a 4 x 4 g + 3a. Then the probability density function j ! of x is given by ! c (x g)2 (H.2) f(x) = 4 xp e 3 ! where ci is the constant that adjusts for the truncation at i3a. In the stratification pro. I ceu for this variable, a quantity of interest would be the fraction of the probability  : between x = 8 + cyrand x = g+ cyr,where c2 and c3 are constants. This frac. l tion is given by

HBR-I.I Appendix ! COMPILATION OF RESULTS FOR HBR HYPO PROBABILISTIC FRACI'URE-MECHANICS ANALYSIS Detailed results for the HBR HYPO probabilistic fracture mechanics analysis are included in this appendix so that a more thorough understanding of. the effect of the various assumptions used in the fracture mechanics model and of the different inputs to the fracture mechanics analysis can be obtained. For instance, the duration of all postulated transients for this study was specified as two hours. As indicated by the, summary sh,ee,ts, in many cases the failures did not occur until late in the transient; thus, if the duration of

                     , the transient had been taken to be one hour instead of two hours, the P(FlE) values would have been reduced substantially.

Sets of data are included in this appendix for most of the transients listed in Table 5.5. Each set includes, in this order, (1) plots of primary system pressure, downcomer coolant temperature and Guid film heat transfer coefficient vs time in the transient; (2) a sum-mary sheet.of digital output that includes F j f f(a/Blalda (referred tp in the data sets as 0

                       " unadjusted P(FlE)") and histogram data for HBR HYPO weld 2 273A on crack

! depths, times of failure, and values of T RTNDT at the crack tip corresponding to initia. l tion and arrest events; (3) a plot of Fj f f(a)Ala)da vs RTNDT, for the (2 D, 2 D) o llaw combination (axial Daws in the plate, and circumferential Daws) and the (2 D, 2 m) Haw combination (axial Daws in axial welds); (4) a plot of vessel wall temperature vs radial position in the wall (a/w) with time (t) as a parameter; (5) a plot of vessel wall temperature vs t with a/w as a parameter; (6) a plot of Kg vs r for 2 D Daws with a/w as a parameter; and (7) a set of critical crack depth curves for HBR HYPO weld 2 273A corresponding to -2a values for K.,i Kg. and RTNDT, mean values of all other parame-ters, and an operating time of 32 EFPY. The summary sheets include the error in the values of P(FlE), based on a 95% confl. dence interval, and also the number of trials (number of vessels simulated), but the number of trials has not been corrected in those cases for which importance sampling was used. If importance sampling was used for one or more of the three affected parameters (crack depth, ARTNDT, RTNDT), one or more of the corresponding quantitles IACCEL, NDLRS, or NRTRS, respectively, will be greater than 0, as indicated near the bottom of the summary sheet. In the case of NDLRS and NRTRS, the number given in the sum-mary sheet (some multiple of a) can be used to obtain the appropriate correction factor from Table 11.1 for the number of trials. For purposes of comparins the various transients. the value of a'v in the summary sheets was always taken to be 1.o. Thus the adjusted value of f(flf) is the same as the unadjusted value. The actual adjusted values can be obtained by multiplying the unadjusted value by the appropriate weld volume (v), imca the best estimate for a is 1.0.
