Dear Chuck,
Part of the project to revise the decay heat rates in Regulatory Guide 3.54 is the comparisons of results from heat rate measurements with those predicted by ORIGEN-S/SAS2.
The comparisons are to be used in both the validations of the calculated data and the determination of safety factors.One set of decay heat rate measurements involved spent-fuel assemblies near 2.5 years cooling time from the Turkey Point Reactor Unit 3.At cooling times less than about 7 years, possible variations in the operating power history can cause significant changes in the decay heat.In the past, it was assumed that the fuel had a constant power and 3 equal irradiation cycle times (see attachment).
It appears that the uncertainty in this history could diminish the value of comparisons of results.Thus, with regards to the above problems, I am asking you to request the utility to obtain or provide satisfactory operating power histories for the following fuel assemblies:
D-15, D-22, D-34 and B-~Y3't is possible that the NRC Office of Reactor Regulation might also have this information.
We have the total burnups of the assemblies and their measured decay heats at various cooling times.The assemblies resided in the reactor during part of the first 4 cycles.The histories could be provided in the most easily available form.They could be average powers (or relative average powers)per assembly vs time.Or, if preferred, the data could be relative power for the entire reactor vs time.In the latter case accumulative burnups per assembly for each cycle would be needed.In order to save time, the data does not need to be given in an extensively formal form (e.g.use of photo copies is adequate).
9005170019 900510 PDR ADOCK 05000250'F'PDC Your assistance in obtaining this requested data is deeply appreciated.
If you have any questions or need additional information, please contact Cecil Parks (FTS-624-5280)or me (FTS-624-5256).

The calculations are biased low by 3.7X with a scatter (1 a)of<lX about this bias.As before, the recirculation data for one assembly (C-64)is inconsistent with the static data and the ORIGEN2 calculation.
For assembly C-52, five static tests and two recirculation tests were conducted to demonstrate system repeatability.
In this case, the values reported in Table 2 are averages, and the static and recirculation results are consistent.
The calculation was in much better agreement with the static measurement and was used in the consistency checks noted above.TABLE 2 COMPARISON OF WEPCO DECAY HEAT CALCULATIONS ANO MEASUREMENTS Burnup Cooling Time Assembly (HWd/HTU)tc (d)Decay Heat (W)Heas Calc C/E C-52 C-52 C-56 C-64 C-64 C-66 C-67 C-68 31,914 31,914 38,917 39,384 39,384 35,433 38,946 37,057 1635 1635 1634 1633 1633 1630 1629 1630 724*694.5 0.959 723'k*921 931*825**846 694.5 893.1 907.8 907.8 809.2 0.961 0.961 0.975 1.100 0.957 934 896.1 0.959 874 851.4 0.974*Static test.**Recirculation test.3.5 TURKEY POINT RESULTS Calculations for the Turkey Point assemblies were completed earlier and reporzed in Reference 1.Since that time, three new calorimeter measure-ments:n tnese assemblies have been made.For completeness, four earlier results are also included.The ORIGEN2 input data are again includea in the Appencix.The calculations were made with an early release of the ORIGEN?
code.In order to ensure that the results are the same when using the most recent release of ORIGEN2, selected calculations, were repeated.The dif-ferences were negligible and were not considered further.The results are presented in Table 3.Except for 0-04 and the second meas-urement on 0-15, the results are excellent.
It is known that thermal equi-librium had not been established in the calorimeter for the 0-04 measurement, thus biasing the measured value low.There is reason to believe the same is true for the low D-15 measurement, especially since this measurement is at a cooling time between two neighboring times where the agreement is good.For the remaining five measurements, the calculations are biased high by 3.8X with a scatter (1 o)of 2.4X,.This agreement is well within the uncer-tainties associated with the measurement and calculations including uncertainties on the reactor operating history.TABLE 3 COMPARISON OF TURKEY POINT DECAY HEAT CALCULATIONS AND MEASUREMENTS Burnup Assembly (MWd/MTU)Cooling Time c (d)Decay Heat (W)Meas Cal c C/E 0-04 0-15 0-15 0-15 0-22 D-34 28,430 28,430 28,430 28,430 26,485 27,863 25,595 913 962 1144 2077 963 864 1782 1385 1555 1423 1491 1126 1217 625 642 1284 1357 1550 1640 637 638 1.123 1.048 1.081 1.027 1.057 1.058 1.002 10 T
elemental oxygen were included.Finally, rounded values of 200 lb of Ziracloy, 28 lb of Inconel, and 2 lb of stainless steel were input, scaled to the elemental inventories given in Table A.4.A.3 TURKEY POINT ASSEHBLIES A.3.1 POWER HISTORY ,The assemblies studied include one Unit 3, Region 2 assembly (B-43)irra-diated in Cycles 1 and 2, and four Unit 3, Region 4 assemblies (D-04, 0-15, 0-22, 0-34)irradiated in Cycles 2-4.The 0 assemblies were all irradiated for 851 EFPO during a residence time of 1073 days.This history was modeled by three full-power periods of 284 days, 284 days, and 283 days separated by two shutdown periods of ill days each.The B-assemblies were irradiated to 827 EFPO during a residence time of 1382 days.The early part of Cycle 1 included an extended period at low power, so that the entire residence time was not modeled.Instead, the power history was assumed to consist of three full-power periods of 259 days, 284 days, and 284 days separated by two ill-day shutdown periods to be consistent with the 0 assembly irradiations.
Burnups were also available and are given in Table A.7.The assembly powers (given in Table A.7)were computed from the reported burnups and the number of EFPO.ASSEHBLY HATERIAL INYENTORIES Taole A.7 also gives the uranium mass and its enrichment for each assembly.Oxygen in the fuel was again taken to be 8406 g-at./HTU.
