Introduction Under contract with the Nuclear Regulatory Commission (NRC), The Pacific Northwest National Laboratory prepared a draft NUREG/CR report, ‘‘Spent Fuel Transportation Package Response to the Caldecott Tunnel Fire (CTF) Scenario.’’ Highway tunnel fire accidents are very low frequency events, but can be severe, in terms of fire duration and peak temperatures. The CTF was chosen for the study because it represents a severe historical highway tunnel accident, even though it is a very low frequency event. This NUREG/CR documents the thermal analysis of one spent fuel transportation package, the NAC International Model No. LWT (‘‘NAC LWT’’), exposed to boundary conditions simulating the CTF scenario. The results of this study strongly indicate that no spent nuclear fuel (SNF) particles or fission products would be released from the NAC LWT or a similar spent fuel shipping cask involved in a severe tunnel fire such as the Caldecott highway tunnel fire. The peak internal temperatures predicted for PO 00000 Frm 00100 Fmt 4703 Sfmt 4703 the NAC LWT in the analysis of the CTF scenario were not high enough to result in rupture of the fuel cladding. Therefore, it would not be expected that any radioactive material (i.e, SNF particles or fission products) would be released from within the fuel rods. The maximum NAC LWT temperatures experienced in the regions of the lid, vent and drain ports exceeded the seals’ rated service temperatures, making it theoretically possible for a small release to occur, due to CRUD that might spall off of the surfaces of the fuel rods. However, any release is expected to be very small due to a number of factors. These include: (1) The tight clearances maintained between the lid and cask body by the lid closure bolts; (2) the low pressure differential between the cask interior and the outside; (3) the tendency of the small clearances to plug; and (4) the tendency of CRUD particles to settle or plate out. The potential releases calculated in Chapter 8 of this report for the NAC LWT truck cask indicate that the release of CRUD from the cask, if any, would be very small—less than an A2 quantity. II.

FOR FURTHER INFORMATION CONTACT: Stephen L. Sharfman, general counsel, at 202–789–6818. SUPPLEMENTARY INFORMATION: Notice is hereby given that on February 14, 2006, the United States Postal Service filed a request with the Postal Rate Commission pursuant to section 3661 of the Postal Reorganization Act, 39 U.S.C. 101 et seq., for an advisory opinion on anticipated changes in the application of current service standards to numerous 3-digit ZIP Code service area origin-destination pairs for different classes of mail.1 The Postal Service states that these changes ‘‘are expected to result from a system-wide review and realignment of the Postal Service’s mail processing and transportation networks.’’ 2 The Postal Service’s request states that it has determined to adopt a process for conducting an in-depth examination and reconfiguration of its mail processing and transportation networks during the next several years. As part of a centrally directed program, the Service anticipates that numerous mail processing and transportation changes will be proposed at the local level and submitted to Postal Service headquarters for approval. Because current service standards for mail delivery are based on logistical considerations, the Service expects that its planned network and transportation changes will result in determinations to adjust some of the service standards that now apply to numerous 3-digit ZIP Code area origin-destination pairs for various classes of mail. However, the Postal Service does not propose to change the ranges of days to delivery incorporated in current service standards for any class or subclass of mail. The Postal Service’s request is accompanied and supported by two pieces of testimony and eight library references. The request and all supporting materials are on file in the Commission’s docket room for inspection during regular business hours, and are available on the Commission’s Web site at https:// www.prc.gov. Proposed procedural schedule and special rules of practice. Also accompanying the Postal Service request is a motion for adoption of an expedited procedural schedule and of special rules of practice that would shorten procedural deadlines for interrogatory response, objections to interrogatories, and replies to motions.3 The Service proposes a sequence of expedited deadlines for discovery, hearings, responsive testimony, and briefs in order to enable the Commission to issue an advisory opinion on its request no later than May 5, 2006. The earliest deadline in the proposed schedule would require a much shorter deadline for interventions that the norm in Commission proceedings. The Postal Service states that it proposes this procedural timetable because it ‘‘presently intends to implement the service changes resulting from the initial wave of operational changes 2 Id. 1 Request of the United States Postal Service for an Advisory Opinion on Changes in Postal Services, February 14, 2006.

SUPPLEMENTARY INFORMATION:

I. Introduction

    Under contract with the Nuclear Regulatory Commission (NRC), The 
Pacific Northwest National Laboratory prepared a draft NUREG/CR report, 
``Spent Fuel Transportation Package Response to the Caldecott Tunnel 
Fire (CTF) Scenario.'' Highway tunnel fire accidents are very low 
frequency events, but can be severe, in terms of fire duration and peak 
temperatures. The CTF was chosen for the study because it represents a 
severe historical highway tunnel accident, even though it is a very low 
frequency event. This NUREG/CR documents the thermal analysis of one 
spent fuel transportation package, the NAC International Model No. LWT 
(``NAC LWT''), exposed to boundary conditions simulating the CTF 
scenario.
    The results of this study strongly indicate that no spent nuclear 
fuel (SNF) particles or fission products would be released from the NAC 
LWT or a similar spent fuel shipping cask involved in a severe tunnel 
fire such as the Caldecott highway tunnel fire. The peak internal 
temperatures predicted for the NAC LWT in the analysis of the CTF 
scenario were not high enough to result in rupture of the fuel 
cladding. Therefore, it would not be expected that any radioactive 
material (i.e, SNF particles or fission products) would be released 
from within the fuel rods.
    The maximum NAC LWT temperatures experienced in the regions of the 
lid, vent and drain ports exceeded the seals' rated service 
temperatures, making it theoretically possible for a small release to 
occur, due to CRUD that might spall off of the surfaces of the fuel 
rods. However, any release is expected to be very small due to a number 
of factors. These include: (1) The tight clearances maintained between 
the lid and cask body by the lid closure bolts; (2) the low pressure 
differential between the cask interior and the outside; (3) the 
tendency of the small clearances to plug; and (4) the tendency of CRUD 
particles to settle or plate out. The potential releases calculated in 
Chapter 8 of this report for the NAC LWT truck cask indicate that the 
release of CRUD from the cask, if any, would be very small--less than 
an A2 quantity.
