REPORT PURSUANT TO 10 CFR 71.95
Dear Mr. White:
CP: 18:01029 UFC:5822.00 January 25, 2018 Nuclear Waste Partnership (NWP) LLC, on behalf of the U.S. Department of Energy Carlsbad Field (?ffice (DOE/CBFO), submits this letter to report a condition pursuant to 10 CFR 71.95 regarding the use of the Type B packaging model number TRUPACT-11, serial number 191. This packaging operates under the U.S. Nuclear Regulatory Commission (NRC) Certificate of Compliance (CofC) No. 9218. During a shipment of transuranic (TRU) waste to the Waste Isolation Pilot Plant (WIPP) originating from Waste Control Specialists (WCS) located near Andrews, Texas, the conditions in Section 10 of CofC No. 9218 were not followed in their entirety.
Following is a description of the event, reported in accordance with 10 CFR 71.95(c):
(1) A brief abstract describing the major occurrences during the event, including all component or system failures that contributed to the event and significant corrective action taken or planned to prevent recurrence:
TRU waste shipment #WC170016 originated from Waste Control Specialists (WCS) in Andrews, Texas, bound for delivery to the WIPP in New Mexico. The shipment consisted of one tractor-trailer hauling three TRUPACT-11 packages, units 154, 158, and 191. Each package contained one payload assembly.
Packages 154 and 158 were designated as 20-day close proximity shipments, and Package 191 was designated as a 10-day controlled shipment in accordance with CH-TRU Payload Appendices 3.5 and 3.6, respectively. Package 191 was subject to the administrative controls identified in section 6.2.3 of the CH-TRAMPAC for transport and unloading time relative to venting of the package at the receiving site.
TRUPACT-11191 was not vented at the WIPP site (receiving site) in accordance with the 9-day transport and unloading time required for a 10-day controlled shipment. CofC 9218 Section 10 specifies, "For close-proximity and controlled shipments meeting the conditions specified in Appendices 3.5 and 3.6, respectively, of CH-TRU Payload Appendices, shipping periods of 20 days and 10 days may be applicable." A failure to fully implement the administr,ative controls (procedures) for TRUPACT-11191 In this shipment at the receiving site resulted in the non-compliance.
There were no major occurrences during the event and no component or system failures that contributed to the event. All other conditions for this shipment were in compliance with the applicable requirements for CofC 9218. However, due to the failure to fully implement the administrative controls (procedures) for TRUPACT-11191 in this shipment at the receiving site, the conditions in CofC 9218 were not followed in their entirety for this shipment.

Document Control Desk CP:18:01029 The following interim corrective/preventive actions were implemented to preclude recurrence:
A review was performed to determine if any additional controlled waste packages were on-site and to confirm the status of those package's vent deadlines. The review concluded that no additional controlled waste packages had exceeded their package vent deadlines and the vent deadlines for those packages were correctly recorded from the WP 08-NT3020 TRU Waste Receipt, Attachment 4, WIPP Control Checklist for Controlled Shipments, to the CH Waste Operations Tailored Shift Briefing.
A Timely Order was developed to identify peer checking vent dates listed on WP 08-NT3020 and on the CH Waste Operations Tailored Shift Briefing form. This Timely Order will remain in place until a more formalized process (procedure) can be developed/issued.
A Root Cause Analysis was chartered to investigate and analyze information associated with the venting issue for shipment #WC170016 TRUPACT 191 to determine the direct, root, and contributing causes.
(2) A clear, specific, narrative description of the event that occurred so that knowledgeable readers conversant with the requirements of part 71, but not familiar with the design of the packaging, can understand the complete event. The narrative description must include the following specific information as appropriate for the particular event:
The NRC-issued CofC 9218 for the TRUPACT-11 specifies in Section 10, "For close-proximity and controlled shipments meeting the conditions specified in Appendices 3.5 and 3.6, respectively, of CH-TRU Payload Appendices, shipping periods of 20 days and 10 days may be applicable." CH-TRU Payload Appendix 3.6 states in section 3.6.3, "The unloading time begins with the arrival of the shipment at the receiving site and ends with the venting of the ICV. Normal unloading will be accomplished In less than one day(24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />). Section 6.2.3 of the CH-TRAMPAC outlines administrative controls imposed to ensure venting of the inner containment vessel (ICV) within 9 days of shipment departure from the shipping site."
The ICV for TRUPACT-11 191 was sealed on 11/20/2017 at 1420 hours0.0164 days <br />0.394 hours <br />0.00235 weeks <br />5.4031e-4 months <br /> {MST) and successfully passed the required pre-shipment leakage rate tests. Then, TRUPACT-11191, which comprised a portion of shipm*ent #WC170016, departed WCS on 11/21/2017 at 1020 hours0.0118 days <br />0.283 hours <br />0.00169 weeks <br />3.8811e-4 months <br /> (MST} and was received at the WIPP Site on 11/21/2017 at 1200 hours0.0139 days <br />0.333 hours <br />0.00198 weeks <br />4.566e-4 months <br /> (MST). The 9-day unloading time was established as 11/30/2017 at 1020 (MST) for TRUPACT-11191. TRUPACT-11191 was vented on 12/01/2017 at 1005 hours0.0116 days <br />0.279 hours <br />0.00166 weeks <br />3.824025e-4 months <br /> (MST).
All other conditions required for the operation and shipment of the package in accordance with the CofC were adhered to.
(2)(/) Status of components or systems that were inoperable at the start of the event and that contributed to the event; This criterion is not applicable to the event because there were no components or systems that were inoperable at the start of the event.
(2)(ii) Dates and approximate times of occurrences; 12/01/2017 at 1005 hours0.0116 days <br />0.279 hours <br />0.00166 weeks <br />3.824025e-4 months <br /> (MST)
{2)(iii) The cause of each component or system failure or personnel error, if known;
Document Control Desk CP:18:01029 No components or systems failed. Waste Handling personnel at the WIPP Site failed to transfer the correct vent date for TRUPACT-11191 from the WP 08-NT3020 Attachment 4 (provided 11/21/2017) to the Waste Handling pre-shift brief. In addition, Waste Handling personnel failed to identify the issue once TRUPACT-11191 was vented.
(2)(iv) The failure mode, mechanism, and effect of each failed component, if known:
This criterion is not applicable to the event because no components failed.
(2)(v) A list of systems or secondary functions that were also affected for failures of components with multiple functions; This criterion.is not applicable to the event because no components failed.
(2)(vi) The method of discovery of each component or system failure or procedural error; Mobile Loading Unit Personnel at WCS discovered that the 9-day transport and unloading time had been exceeded during reconciliation of records to close out shipment #WC170016.
(2)(vii) For each human performance-related root cause, a discussion of the cause(s) and circumstances,,*
A Waste Handling Engineer incorrectly recorded the package vent deadline date and trme of 11/30/2017 1020 from the WIPP Control Checklist for Controlled Shipments to the CH Waste Operations Tailored Shift Briefing as 12/10/2017.
,o, Shipment#WC170016 arrived on site at 1200 hours0.0139 days <br />0.333 hours <br />0.00198 weeks <br />4.566e-4 months <br /> on 11/21/2017, with three packages on the shipment, TRUPACT-11 units 154, 158, and 191. TRUPACT-11 191 was a controlled shipment with a required venting deadline of 11/30/2017 at 1020 hours0.0118 days <br />0.283 hours <br />0.00169 weeks <br />3.8811e-4 months <br />, while TRUPACT-11 units 154 and 158 were 20-day shipments with a required venting deadline date of 12/10/2017. This may have contributed to the Waste Handling Engineer having incorrectly recorded the vent deadline for TRUPACT-11191 from the WIPP Control Checklist for Controlled Shipments to the CH Waste Operations Tailored Shift Briefing as 12/10/2017.
(2)(viii) The manufacturer and model number (or other identification) of each component that failed during the event; and Manufacturer and model numbers associated with component failure are not applicable because no components failed.

There were no systems or components that failed during the event. There were no safety consequences or implications of the event.
( 4) A description of any corrective actions planned as a result of the event, including the means employed to repair any defects, and actions taken to reduce the probability of similar events occurring in the future.
In addition to the interim corrective actions identified in (1) above the following preventative corrective actions are planned:
Proceduralize the CH Waste Operations Tailored Shift Briefing to include signoff and verification of Package vent deadline date and time against the WP 08-NT3020 Attachment 4.
Revise technical procedure WP 08-NT3020 to formalize the transfer of the vent date information for controlled shipments from the WP 08-NT3020 Attachment 4 to the CH Waste Operations Tailored Shift Briefing. This process will include sign offs and independent peer verification.
Revise the Waste.Data System (WDS) to:
o Calculate the package vent date/time limits for 10-day, 20-day, and 60-day packages; display the value on the Shipment Summary Report; and, o
Add a column for vent completion dates/times that Waste Operations can populate upon completing venting of waste packages.
Interim measure to prevent reoccurrence:
Develop a computer script that will run a daily query of all loaded packages at WIPP showing vent date/time. This script will provide a query daily to Transportation and Waste Handling Operations. _This script will remain in effect until the (WDS) can be revised accordingly.
Develop and Issue a Timely Order to Transportation Engineers and Waste Handling Engineers to review the daily query at the beginning of their shift until the WDS is revised.
Brief Waste Handling Engineers on the programmatic drivers for venting controlled packages.
Establish an electronic means for displaying the CH Waste Operations Tailored Shift Briefing at the watch desk in the Waste Handling Building.
