Reusable Half Height ISO (RHHISO)

• ITT has been issued to five companies for the
  design and certification of RHHISO
• RHHISO works with infrastructure at existing
  sites and is compatible with new build
  assumptions
• Top opening, fully lined load area with tie down
  points to facilitate consignment of smaller
  quantities of segregated waste
• Options for multiple inner containers being
  assessed (magazine)
• Available within 12 months, (subject to
  licensing)

• Waste Tracking System
• - Roll Out Implementation

21
Working together - early days Waste Tracking

• Planning and selection over a two year period
• Site users (now the WTS User Group) were involved
  in development of the WTS user specifications.
  Specific engagement of those individuals
  responsible for shipping radioactive waste to the
  LLRW and other disposal locations
• LLWR staff and MxS Site users participated in the
  procurement process and the selection of the
  web-based tracking system.
• NDA was consulted with during the specifications
  development and procurement process.

22
Benefits and Attributes

• An off the shelf system with a proven track
  record in waste management and decommissioning
  for multiple sites
• enhanced interface with LLWR
• provides one database for all waste inventory
  radioactive, hazardous non-radioactive in
  process - on site
• Required reports generated from a single database
• tracks waste from pick up through storage,
  treatment, segregation, one to many containers
  and many to one container and disposal
• interfaces with a barcode system for field
  operations
• database is flexible to accommodate multiple
  waste streams and disposal CfAs

23
Benefits and Features

• Virtual shipping configurations prior to loading
  assures quality in packaging and minimises
  reloading
• Provides shipping documents for approval from
  initial data entry.
• Transfer of data electronically to another
  database.
• Generates a compliance report of waste being
  managed against pre-determined set of parameters
  (waste streams, storage restrictions,
  transportation limits, CfAs, etc.)

24
Working Together Shared Learning / Broadening
Acceptance

• MxS WTS database training sessions provided by
  the vendor attendance by LLWR staff ( N.
  Solente, J. Evans )
• Magnox North has participated in application
  overviews and MxS User Group
• All MxS sites will be utilising the same system
  with site specific profiles

eMWaste training Warrington 7April

• The WTS software is to be established at a
  centrally located restricted server, accessed
  via MxS wide area network(WAN)

25
LLWR perspective

• Benefits WTS reduces manual data entry and
  associated errors
• Electronic data transfer
• Front-end compliance checks
• Bar-coding of consignments
• Measurements data written to database
• WTS potential use integrated system waste
  reduces management complexity
• Waste treatment and disposal management and
  records
• Logistics and container fleet management
• Common system benefits standardisation increases
  benefits
• Lessons learnt and improvements shared benefits
  for users and taxpayers
• Single data format faster, simpler treatment
  disposal authorisations

26
Current inventories and forecast

• Inventory Low Level Waste Stored Future
  arising,
  Range 100 years
• Forecast Expected consignments sent for
  treatment and disposal.
• Range 0- 36 months

• Inventory 2 inventories
• National inventory 2007
• WIDRAM 2008 (NDA sites) from NI2007 and Waste
  Accountancy Templates
• Inconsistencies, errors in volumes, radionuclides
  and activities, do not always reflect newer waste
  segregation practices
• Forecast
• LLWR Operational Forecast. Range 12 months
• Inaccurate until 2008
• In 2008 20 of the forecasted year disposal
  charges up-front at a discounted rate
• Large improvement in forecast accuracy

27
Waste forecast and inventory improvement project

• Business drivers
• Support Strategy ex. Future needed treatments and
  disposal capacity
• Provide quality input to Environmental Safety
  Case
• Allows reliable Operations forecast
• Shorter data gathering and processing cycle
• Goals
• Smooth transition from current process
• Improve all phases of inventory and forecast,
  starting at data collection
• Coordinated effort and shared practices
• Real time inventory

28
2008-2009 achievements

• WIDRAM data review driven by Environmental Safety
  Case
• Several problems identified and resolved by
  direct contact with consignors waste teams
• Limited resources concentrated on key
  wastestreams and radionuclides provided good
  results and a significant improvement in
  inventory reliability
• Common sources of errors, missing data and
  inconsistencies from WAT data entry identified.
  Easy to implement, short term solutions submitted
  for distribution to SLCs through NDA
• Scoping of Forecast improvement project defined

Characterisation Monitoring projects

• Business drivers increase the overall level of
  characterisation quality
• Better characterisation enables better
  segregation
• Reduces phantom activity excess activity
  declared due to conservative assumptions
  associated with poor characterisation
• Goals
• Minimize impact to consignors
• Facilitate waste hierarchy implementation
• Provide more accurate data to Environmental
  Safety Case

31
Waste characterisation project scope

• LLWR is preparing a guidance document relating to
  Radiological Characterisation.
• This guidance document is not a working practice
  or method statement and whilst it contains some
  specific measurement techniques, it should not be
  considered a definitive list.
• It contains guidance on industry best practice
  relating to Radiological Characterisation.

32
Waste characterisation project output

• The Radiological Characterisation Guidance
  document is designed to set out Best Practice
  principles.
• The guidance is designed to aid consignors in
  completing the Radionuclide Fingerprint and
  Activity Assessment sections of the WasteStream
  Characterisation Document.
• The guidance does not contain an inclusive list
  of techniques that may be used but it does
  contain guidance on how new techniques should be
  communicated to LLWR.
