Report HI-2177597 1
Project 5025 1.0 PURPOSE AND SCOPE At New Mexico consolidated interim storage facility, the loaded MPCs are transferred from HI-STAR 190 [1] to HI-TRAC CS [2] using Canister Transfer Facility (CTF) [3]. This report documents evaluations to demonstrate compliance of all short-term operations involving HI-STAR 190 to the thermal requirements in Chapter 4 of HI-STORE SAR [4].
Before the HI-STAR 190 cask is placed into the CTF, the impact limiters are removed and the cask cavity is evacuated and backfilled with nitrogen. After the HI-STAR 190 cask is placed into the CTF, the HI-TRAC CS alignment plate is installed on top of the CTF. A thermal evaluation is performed for the thermally limiting short-term operation condition of HI-STAR 190 inside the CTF as described below:
(1) HI-STAR 190 with MPC is placed inside the CTF. The HI-TRAC CS alignment plate is installed on the CTF.
(2) The HI-STAR 190 cask closure lid is in place. The HI-TRAC CS cask is not placed in the stack-up position above the CTF.
(3) The cask cavity is filled with nitrogen.
The closure lid of the HI-STAR 190 cask is then removed. The HI-TRAC CS cask is placed on the alignment plate with its bottom shield gates open. After the MPC is lifted into the HI-TRAC CS cask, the HI-TRAC CS shield gates are closed and the MPC is rested on the shield gates.
The HI-TRAC CS cask is then lifted and placed at a location on the floor that is accessible to the VCT.
After the closure lid is removed, the HI-STAR 190 cask cavity is filled with air. The thermal conductivity of nitrogen is slightly lower than that of air. Therefore, the thermal performance of the HI-STAR 190 cask after its closure lid is removed and before the MPC is lifted into the HI-TRAC CS cask is bounded by that under the short-term operation condition described above.
Once the MPC is lifted into the HI-TRAC CS cask, the thermal performance is bounded by those evaluated in Ref. [7].
For hypothetical accident, the worst cask transfer building (CTB) collapse scenario is evaluated as described below:
(1) HI-STAR 190 with MPC is placed inside the CTF. The HI-TRAC CS alignment plate is installed on the CTF.
(2) The HI-STAR 190 cask closure lid is in place. The HI-TRAC CS cask is not placed in the stack-up position above the CTF.

Project 5025 2.0 METHODOLOGY AND ASSUMPTIONS To accommodate all BWR and all PWR canisters, the HI-STAR 190 cask is available in two discrete lengths: Version SL (standard length) and Version XL (extended length) [1]. The HI-STAR 190 Version XL has a larger external surface for heat dissipation than that of HI-STAR 190 Version SL, and thus the thermal performance of HI-STAR 190 Version XL is bounded by that of HI-STAR 190 Version SL. According to Ref. [8], the bounding configuration of MPC in vertical orientation is MPC-37 loaded with [PROPRIETARY PER 10CFR2.390]. Therefore, the HI-STAR 190 Version SL containing MPC-37 loaded with [PROPRIETARY PER 10CFR2.390]
is adopted to yield bounding results. It bounds the configurations below.
(1) Short fuel in MPC-37 within HI-STAR 190 Version SL (2) Standard fuel in MPC-37 within HI-STAR 190 Version SL (3) Long fuel in MPC-37 within HI-STAR 190 Version XL (4) MPC-89 within HI-STAR 190 Version SL In Appendix F of Ref. [9], HI-STAR 190 Version SL in an open space (without the CTF) containing MPC-37 loaded with [PROPRIETARY PER 10CFR2.390] is evaluated. This model is the same as that provided in Section 3.3 of HI-STAR 190 SAR [5]. The 3D quarter-symmetric model of HI-STAR 190 in Appendix F of Ref. [9] is adopted and modified as follows:

Project 5025 The HI-STAR 190 Version SL is placed [PROPRIETARY PER 10CFR2.390] inside CTF [3].
The 3D quarter-symmetric model of HI-STAR 190 Version SL inside CTF is illustrated in Figure 2.1 and a 2D cross-section of the CTF cavity is presented in Figure 2.2. The CTF geometry added to the HI-STAR 190 model includes

Following Ref. [8], the thermal evaluations are performed for the bounding heat load pattern, i.e.
heat load pattern 1 presented in Table 1.1 of Ref. [8]. The MPC is initially backfilled with helium ATTACHMENT 5 TO HOLTEC LETTER 5025029 Page 10 of 26
Report HI-2177597 5
Project 5025 in the pressure range specified in Table 1.3 of Ref. [8]. Inside the CTF, the MPC cavity pressure increases with the MPC cavity temperature. Using the minimum backfill pressure specified in Table 1.3 of Ref. [8] and the MPC cavity average temperature predicted in Section 6.0, the minimum MPC cavity pressure under the operation conditions is computed by ideal gas law. The MPC cavity pressure adopted in the simulations is slightly lower than the calculated minimum MPC cavity pressure, which understates the thermo-siphon effect inside the MPC cavity and thereby overestimates the peak cladding temperature.

Project 5025 3.0 INPUT DATA The principal geometric parameters for HI-STAR 190, CTF, MPC-37 and basket are taken from design drawings [1], [3], [12] and [13]. Materials present in the HI-STAR 190 cask include
[PROPRIETARY PER 10CFR2.390 ]. The physical properties of these materials are obtained from HI-STAR 190 SAR [5]. The properties of air are also obtained from HI-STAR 190 SAR [5]. The properties of nitrogen are obtained from Ref.
[14] and presented in Table 3.1. It is noted that the temperatures of Holtite-B may be higher than its design temperature limit under the CTB collapse accident. [PROPRIETARY PER 10CFR2.390
].
The surface emissivities are obtained from HI-STAR 190 SAR [5]. For the HI-STAR 190 cask cavity surface, the emissivity of carbon steel without paint is assumed for conservatism.
[PROPRIETARY PER 10CFR2.390
].
The CTF is inside the cask transfer building and thus there is no insolation. The ambient temperature adopted in the evaluations is 32.8oC (91oF), as specified in HI-STORE SAR [4]. The ambient pressure adopted in the evaluations is [PROPRIETARY PER 10CFR2.390], which is conservatively lower than the actual ambient pressure at the site elevation specified in HI-STORE SAR [4]. The limiting heat load pattern and the corresponding MPC backfill pressure range as descried in Section 2.0 are adopted to yield bounding results.

Report HI-2177597 10 Project 5025 6.0 RESULTS AND DISCUSSIONS 6.1 Thermal Evaluation of Short-Term Operation A steady state simulation is performed for the short-term operation scenario described in Section 1.0. The evaluation is performed for most limiting thermal configuration under the bounding heat load pattern, as described in Section 2.0. The predicted fuel temperature and component temperatures are presented in Table 6.1. The fuel temperature and component temperatures are below their limits specified in Section 4.0 for short-term operation.
6.2 Thermal Evaluation of CTB Collapse Accident A steady state simulation is performed for the worst CTB collapse accident scenario described in Section 1.0. The evaluation is performed for most limiting thermal configuration under the bounding heat load pattern, as described in Section 2.0. The predicted fuel temperature and component temperatures are presented in Table 6.2. The fuel temperature and component temperatures are below their limits specified in Section 4.0 for accident condition.
6.3 Maximum Normal Operation Pressure (MNOP)
For heat load pattern 1 presented in Table 1.1 of Ref. [8], the MPC is initially backfilled with helium in the pressure range specified in Table 1.3 of Ref. [8]. Inside CTF, the MPC cavity pressure increases as the MPC cavity temperature increases. Using the maximum backfill pressure specified in Table 1.3 of Ref. [8] and the MPC cavity average temperatures predicted in Sections 6.1 and 6.2, the maximum MPC cavity pressures are determined by ideal gas law and presented in Table 6.3.
6.4 Differential Thermal Expansion In this section, thermal expansion of components inside HI-STAR 190 in the radial and axial directions is computed. The calculations address the following thermal expansions:

Report HI-2177597 13 Project 5025 6.5 Discussion and Conclusion Based on the results presented in Sections 6.1 thru 6.4, the following conclusions are drawn:
- 1. During short-term operation inside CTF, the fuel cladding temperature and the MPC and cask component temperatures remain below their short-term temperature limits indefinitely. The MPC cavity pressure also remains below its short-term pressure limit.
- 2. Under CTB collapse accident event, the fuel cladding temperature and the MPC and cask component temperatures remain below their accident temperature limits. The MPC cavity pressure also remains below its accident pressure limit.
- 3. Free thermal expansion is ensured for fuel, basket and MPC for both short-term operation and CTB collapse accident event.
Thermal evaluations in Section 3.3.5 of HI-STAR 190 SAR [5] demonstrate that the predicted temperatures and cavity pressures under sub-design basis heat loads is bounded by design maximum heat load scenario. Therefore, the above conclusions remain applicable to sub-design basis heat loads also.
