CONFERENCE AND EXHIBITIONJune 22, 2016
Aleksandr GelfondEnergySolutions
SUMMARY
EnergySolutions (ES) cask inventory 3-60B Cask Update Major developments associated with user interface and
equipment improvements in 2016 Short and Long Term Goals Latest licensing update on ES Type (B) packages. ANSI N 14.5 (1997 and 2014) pre-shipment leakage

ENERGYSOLUTIONS CASK INVENTORY
DOT 7A Type A casks – 80 unitsincluding 6-80-2, 8-120A,10-142A, 14-170,14-190,14-195,14-210,14-215 and21-300 casks models Type B Packages – 10 units (including
8-120B, 10-160B, 3-60B) IP-1 Packages - 4 units (including
18-450, 27-415 and IP-1 TCT caskmodels)
3-60B CASK UPDATE Newly designed 3-60B Type (B)
Cask was built within one year Most of lessons learned from
fabrication of 8-120B casks wereimplemented No significant issues during
fabrication, receipt inspection anddry runs were identified
3-60B CASK UPDATE
Development of handling and maintenance procedures along with work instructions Dry runs at EnergySolutions and WCS
facilities Field load testing of the equipment Development of special fixtures to be used
during horizontal/vertical handling of the cask Completion of the first annual maintenance Two successful loading at Vermont Yankee
NPP Capturing lessons learned
OPERATIONAL EXPERIENCE
Monitor physical condition of casks, inspect for damages and perform periodic maintenance.Common issues: Backing out of threaded inserts
from closure bolt holes Improper use of ratchet
binders Damage of MT&E equipment Minor damages of cask
components
EQUIPMENT IMPROVEMENTS Replacing ratchet binders on old 8-120B casks Long awaited restoration of casks/packages is
underway Improvement in a periodic leak test methodology
for Type (B) packages Procurement of brand new trailers for all 8-120B
cask is underway
CUSTOMER INTERFACE IMPROVEMENTS
Establishment of EnergySolutions Web based Customer Portal https://customerportal.energysolutions.com which provides access to the following essential documentation:• Cask Manuals which includes cask related procedures• Safety Analysis Reports and Certificates of Compliance• Technical Bulletins• Position Papers • Newsletters on significant developments/events distributed
to the cask users. In addition, EnergySolutions customer (s) are provided with Payload Qualification Verification Support for Type (B) packages
TYPE (B) CASK TRAINING FOR CASK USERSHands-on training on 8-120B cask which includes: Handling of the cask and its major components Inspection of critical components of the cask Cask closure Pre-shipment leakage rate testing consideration Proper reporting of non-compliant components
BARNWELL LOGISTICS FACILITY (BLF)
Cask and cask trailer maintenance work is performed in the cask maintenance facility in Barnwell, SC Limited cask and trailer maintenance is performed at satellite
locations located at EnergySolutions Bear Creek (TN) and Clive (UT) facilities.
TYPICAL MAINTENANCE ACTIVITIES AT BLF
Maintenance of the cask components ( fasteners, ratchet binders, tie-downs) Maintenance of trailers ( mechanical and electrical work) Refurbishment of the cask and trailers ( sanding, painting) Replacement of cask components with minor and medium
weld repairs ( ex. changing Type (B) casks impact limiter skins) Change of cask seals and maintenance/ periodic leak
tests Load tests of lifting attachment of the casks and
components NDE inspections (VT,MT,PT,UT)
LICENSING UPDATE (8-120B CASK)In 2015: CoC Rev. 22 (Current): Include cladding tubes in 8-120B
secondary lids as part of authorized configuration. In 2016 (In progress): Amendment request was submitted to add gross- dewatered resins
as one of authorized payloads. Response to NRC RAI’s were provided on May 12, 2016 Anticipated acceptance of Amendment request by NRC is Fall of
2016In 2017 (future work) Add additional payload specifications by introducing a family of
shielded inserts for 8-120B casks
LICENSING UPDATE (10-160B and 3-60B CASKS)
10-160B cask (USA/9204/B(U)F-96)Rev. 22 of CoC was authorized via timely renewal process onAugust 14, 2015 with expiration date of October 31, 2020. Noplanned Amendment request for this CoC is expected at thistime. 3-60B cask (USA/9321/B(U)-96)Rev. 2 of CoC USA/9321/B(U)-96 was authorized via timelyrenewal process on September 30, 2015 with expiration date ofSeptember 30, 2020. No planned Amendment request for thisCoC is expected at this time.
SHORT AND LONG TERM GOALS
Purchase and refurbishment of trailers for Type (A) and Type (B) casks. Introduction of new casks into fleet/ refurbishment of the existing casks. Complete annual load tests and NDE for 8-120B casks that have 4
lifting points (fully comply with NUREG-0612 requirements). Purchasing of new cask ancillary components and keeping readily
available inventory on hand (ratchet binders, gauges, manifolds, fasteners).
Continuous improvement of procedures based on the latest regulatory and standards requirements, industry practices and customer’s input.
Improvement of the user experience during pre-shipment leak tests in accordance with new revision of ANSI N 14.5-2014.
Enhancing EnergySolutions Web based Customer Portal
PRE-SHIPMENT LEAKAGE RATE TESTING BASED ON ANSI N14.5-1997
ANSI N14.5 “ American National Standard for Radioactive Materials – Leakage Tests on Packages for Shipment” Certificate of Compliance for 8-120B/10-160B packages
along with Chapters 7 and 8 of respective Safety Analysis Reports (SAR) and ANSI N14.5-1997 provide leakage rates test requirements. ANSI N 14.5-1997 requirements for training/qualification of
users performing pre-shipment leakage rate test Section 8.5: Trained and qualified personnel shall perform leakage testing in accordance with written procedures and document the results.Section 8.8 : Leakage rate testing shall be performed in accordance with a written quality assurance program.
UPCOMING CHANGES FOR THE PRE-SHIPMENT LEKAGE RATE TESTING ASSOCIATED WITH ANSI N14.5-2014
NRC INFORMATION NOTICE 2016-04 : ANSI N14.5- 2014 Revision and Leakage Rate Testing Considerations, May 28, 2016 ANSI N 14.5-2014 Revision and Leakage Rate Testing
Considerations by JoAnn Ireland, NRC presented at NMSS/DSFM REG CON on November 19, 2015 It is expected that ANSI N 14.5-2014 essential requirements will be
incorporated in 8-120B/10-160B package CoC’s in 2017.
ANSI N 14.5-2014 requirementsMain changes that will be imposed by ANSI N 14.5-2014 for pre-shipment leakage rate testing:Procedures/Equipment Procedure shall be qualified to ensure meaningful leakage test results Pre-shipment leakage rate resting procedures shall be approved by
personnel whose qualifications and certifications in the NDT of leak testing includes certification by a nationally recognized society at a level appropriate to the writing and/or review of leakage test procedures (ASNT NDT Level III in Leak Testing).
Procedure and equipment for pre-shipment leakage rate testing may be changed.
Qualification to perform pre-shipment leakage rate testing Testing shall be performed by personnel qualified and certified in
accordance with American Society for NDT (ASNT) SNT-TC-1A ( Level II).
EnergySolutions’ Initiative To Upcoming ANSI N14.5-2014 Requirements
In anticipation of incorporation of ANSI N14.5-2014 requirement (in 2017): Effort is under development to qualify leakage test procedures for
8-120B and10-160B casks based on new requirements. Effort is under development to develop EnergySolutions NDT
written practice ( based on SNT-TC-1A) to cover a pre-shipment leakage rate testing and qualify/certify EnergySolutions limited staff to perform a pre-shipment leakage rate testing on 8-120B/10-160B casks (as NDT Level II with Limited Certification). Cask users will have a choice between qualifying their own NDT
personnel that will operate under user’s QA program or using approved/qualified/certified subcontractors to perform a pre-shipment leakage rate test.
