Case Study – WIPP Radiological Release
NSE 515 11/21/2018
The Waste Isolation Pilot Plant (WIPP) was authorized by congress in 1979, when it began to be
apparent that the nation needed a long-term solution for disposal of transuranic wastes (TRU).
The WIPP is located near Carlsbad, New Mexico in a bedded salt mine. This is a geologically
stable, water-free salt cavern which will slowly encapsulate the nuclear wastes over time,
providing a stable long-term solution for storage of nuclear waste.
Construction of the facility was completed in 1989, but the facility did not begin accepting
waste until 1999, due to an agreement between the U.S. Department of Energy and the State of
New Mexico that the facility would not be able to accept wastes until it received a Resource
Conservation and Recovery Act (RCRA) Part B Permit, for treatment, storage and disposal of
regulated hazardous wastes.
In 1999, the facility begins receiving TRU waste shipments from DOE facilities including Los
Alamos National Lab, Idaho National Lab, Rocky Flats Environmental Technology Site, Argonne
National Lab, and Hanford. The facility operated safely from 1999 to 2014.
WIPP is operated by prime contractor Nuclear Waste Partnership LLC, which is a joint entity
lead by AECOM Corporation (full disclosure: I am an employee of AECOM on a different
Department of Energy contract). In 2014, waste receiving was temporarily shut down due to a
fire on a salt hauling truck. A few days later, the facility experienced a radiological release from
a waste drum in Room 7, Panel 7, with airborne contamination released to the environment.
The facility was inspected by the U.S. Environmental Protection Agency for compliance with 40
CFR Part 191, Subpart A Environmental Radiation Protection Standards for Management and
Disposal of Spent Nuclear Fuel, High-Level and Transuranic Radioactive Wastes, and 40 CFR Part
61 Subpart H National Emissions Standards For Emission of Radionuclides Other than Radon
from Department of Energy Facilities, both of which regulations address radioactive dose to the
public by exposure to contaminants in the air released from Department of Energy radioactive
waste disposal facilities.
The release occurred in a single drum of TRU waste from Los Alamos National Lab. This drum
contained TRU waste materials which had been packed with an absorbent called Swheat
Scoop™. Absorbent materials are used to cushion and absorb any leakage from smaller
containers packed into a drum, in a process known as lab packing or over packing. Traditionally,
diatomaceous earth (kitty litter) or vermiculite are used for this purpose, as they are
compatible, or non-reactive, with most reactive and hazardous chemicals. A replacement
product, Swheat Scoop™, was purchased as an alternative to diatomaceous earth. Personnel
did not realize that Swheat Scoop™ is an organic-based absorbent, and is incompatible with
strong oxidizers and other reactive chemicals.

Lake Ontario Waterkeeper's submissions for Pickering Waste Management Facilit...LOWaterkeeper
Ontario Power Generation (OPG) is currently applying to renew its Waste Facility Operating Licence for its Pickering Waste Management Facility (PWMF). The current licence
will expire March 31, 2018.
OPG is currently requesting a licence term of approximately 11 years that will expire on August 31, 2028.
Waterkeeper's written submissions discuss several identified concerns with the PWMF and provide
recommendations for improving the facility’s planned expansion and routine operations.
Even with the implementation of waste
reduction, recycling, material recovery and
transformation technologies, disposal of solid
waste in a landfill remains an important
component of solid waste management
strategies.
• It is not always economical to recycle/recover
all waste under all conditions.
• Safe and reliable long-term disposal of solid
waste is one of the most essential components
of solid waste management.
• The landfill is the most economical form of solid
waste disposal that minimises adverse
environmental effects, associated risks and
inconveniences; allowing the waste to
decompose under controlled conditions
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

WIPP Recovery and Lessons Learned
Tammy Reynolds – Deputy Project Manager
Nuclear Waste Partnership LLC
Washington, DC
September 7-9, 2016
2. WIPP Recovery and Lessons Learned
Background
The Waste Isolation Pilot Plant (WIPP), located in New Mexico began construction in the
early 1980’s
Receipt and disposal of Contact Handled (CH) waste began in March 1999
Receipt and disposal of Remote Handled (RH) waste began in January 2007
Between March 1999 and February 2014, WIPP safely and compliantly:
Received 11, 894 shipments and disposed the waste in the u/g,
90,627 cubic meters of CH TRU waste,
357 cubic meters of RH TRU waste
In February 2014, WIPP operations were paused when a fire and a radiological event
occurred in the underground
Recovery from the events is in progress and planned to be complete by the end of calendar
year 2016. Commencement of waste emplacement activities will begin as soon as it is safe
to do so.
2
3. WIPP Recovery and Lessons Learned
Fire Event
February 5, 2014 a fire occurred in the u/g involving a salt haul truck
86 workers in the u/g at the time of the fire were safely evacuated
Investigated by both DOE and NWP
DOE Accident Investigation Report issued on March 13, 2014
Radiological Event
February 14, 2014 an exothermic reaction involving the mixture of the organic materials (absorbent
and/or neutralizer) and nitrate salts occurred inside a drum.
Pressurization of the drum, failure of the drum locking ring, and displacement of the drum lid
TRU waste propelled from the drum up into the polypropylene magnesium oxide (MgO) super
sacks on top of the containers and onto adjacent waste containers.
(Note: MgO is an assurance feature to ensure consistent and favorable chemical conditions are
maintained in the brines after final facility closure by reacting with any carbon dioxide produced
by the decay of organic carbon in the waste and waste emplacement materials.)
Radiological Continuous Air Monitor (CAM) alarm received; ventilation interlocked to filtration
mode
Small amount of leakage bypassed the HEPA filters and released into the atmosphere
DOE Accident Investigation Report Phase I (response to the event) – issued on April 22, 2014
DOE Accident Investigation Report Phase II (cause of the event) – issued on April 16, 2015 3
4. WIPP Recovery and Lessons Learned
Lessons Learned
Nuclear Facility vs Mine Culture
Although WIPP is a nuclear facility, there was a mining culture in place vs a nuclear culture
Difference in expectations between waste handling and non-waste handling vehicles
(combustible buildup, manual vs auto fire detection/suppression)
Operability and recognition of impaired critical safety equipment
Fire protection program not adequately implemented at the WIPP facility
No controls or programs in place for control of combustible materials or maintaining of fire
protection support systems
Maintenance program not effectively implemented
– Combustible buildup on salt haul truck; chaining open ventilation doors; inoperable
ventilation fans; inoperable mine phones, obscured evacuation reflectors, disabling of
auto fire suppressions system; no overall method to understand status and impact of
impaired mine safety related equipment
Mindset of production over maintenance based on complex wide priorities to accelerate
shipments from generator sites in support of individual site milestones and regulatory agreements

5. WIPP Recovery and Lessons Learned
Lessons Learned
Training and drill programs
Emergency management/preparedness and response programs not effectively implemented
Limited drills, inadequate donning of self-rescuers or SCSRs during training or drills,
or hands on training with portable fire extinguishers
Inconsistencies between u/g fire response procedures and drills/training
(shifting ventilation during evacuation)
Expectations and capabilities of the Facility Shift Manager to manage all aspects of an
emergency or abnormal event
CMR response (evaluation and protective actions) was less than adequate
Identified problems with communications and alarms during the fire/evacuation
delaying egress
National TRU Program not robust enough to identify incompatible waste
Communications to the community and regulatory stakeholders was not timely
Ensures trust is maintained rather than rebuilding that trust
