Re: Freedom ofInformation Act Request

Dear Mr. Powell:

Pursuant to the Freedom ofInformation Act,5 U.S.C. 522, as amended and 10 C.F.R. Part 9.41, the Wisconsin Citizens' Utilhy Board (CUB) requests the following documents:

1. Please provide any and all documents that contain information on the results of the demonstration of examination techniques of VSC-24 lid welds, which began in April,1998, at Palisades nuclear plant.

For purposes of this request, please consider " documents" to include reports, studies, test results, correspondence, memoranda, meeting notes, meeting minutes, working papers, graphs, charts, diagrams, notes and summaries of conversations and interviews, computer records, electronic mail and any other form of written communications including internal NRC memoranda.

Pursuant to and in compliance with 10 C.F.R. 9.41 of the agency's regulations and 5 U.S.C. 552 governing requests for waiver of fees, CUB puts forth the following information.

CUB was incorporated pursuant to Chapter 181,1979, of the Wisconsin Statutues. CUB is exempt from Federal income tax under Section 501(c)(4) of the Internal Revenue Code. CUB is also exempt from Wisconsin franchise tax.

The restricted fund (public interest fund)is exempt from Federal income tax under Section 501(c)(3) of the Internal Revenue Code. The fund is also exempt from Wisconsin income taxes.

. The public interest fund was established on February 1,1981, and reorganized on April 28,1986 .

{ to correspond to the new stmeture of the CUB. The fund engages in charitable, scientific, literary and educational activities on behalf of CUB.

CUB has 26,000 members who are residential ratepayers in Wisconsin. CUB represents the more than two million residential ratepayers in the state. CUB's purpose continues to be the statutory purpose set forth under sec.199.02, Wis. Stats.: -

' ~

....to promote the health, welfare and prosperity of all the citizens ,

of this state by ensuring effective and democratic representation of -

individual farmers and other individual residential utility consumers ,

before regulatory agencies, the legislature and other public bodies and by providing for consumer education on utility service costs and on benefits and methods of energy conservation.

CUB seeks the requested information to become informed of the results of the demonstration of examination techniques of VSC-24 lid welds at the Palisades nuclear plant.

The examination techniques were being tested to determine their usefulness in identifying the -

acceptability of VSC-24 lid welds. Demonstration of examination techniques of VSC-24 lid welds were also conducted at the Arkansas Nuclear One plant during March,1998. The results .

of those tests are the subject of FOIA/PA 98-164. A Wisconsin utility's plans for loading VSC-24 casks with high level radioactive waste will be affected by the results of the demonstrations.

CUB intends to use the information to assist it in its participation in any proceedings before Wisconsin regulatory agencies, and as part of CUB's ongoing effort to educate the public on nuclear energy issues in Wisconsin.

The information sought, is not, to the best of our knowledge, in the public domain. The general public in Wisconsin has displayed great interest in nuclear energy issues and have a direct interest in information regarding the operational performance of the VSC-24 cask. A Wisconsin utility currently uses the VSC-24 cask to store spent nuclear fuel near the shore of Lake Michigan.

CUB has. demonstrated its ability and commitment to inform the public on all important nuclear energy issues in Wisconsin. CUB provides this information free of charge through newsletters, educational pamphlets, and correspondence to its members, other residential ratepayers, legislators, and policy makers, and has neither a commercial nor a private interest in the agency records sought.

Under the amended fee waiver standard, CUB is clearly entitled to a full waiver of all search, review and duplication fees. This standard calls for such a waiver, "if disclosure of the information is in the public interest because it is likely to contribute significantly to the public' understanding of the operation or activities of the government and is not primarily in the commercial interest of the requester." 5. U.S.C. 552(IX4XAXiii).

In light of the foregoing, CUB meets this standard on its face. CUB has no commercial ,

interest in this matter, but rather seeks this information to help the general public and state regulatory agencies better understand the role of the federal government in regulating the nuclear power industry. .

2 O___________________-__-_-_-

For the reasons cited above, CUB's request falls squarely within the Congressional intent in enacting the Freedom ofInformation Act and the fee waiver provision. CUB, therefore, asks that the NRC grant a full fee waiver for this FOIA request.- -

Thank you for your anticipated cooperation. If you have any questions in regards to this' ,

request, please feel free to contact me at your earliest convenience. Please contact me before -

acquiring and sending the requested information if the fee waiver is not applied.

  • Sincerely, Dennis Dums

Update on the VSC-24 weld issues The following is in response to your request for the status on the VSC-24 weld issues.

j Update on the VSC-24 weld issues:

Last week, the VSC-24 Owners Group (Sierra Nuclear Corporation, Pt. Beach, Palisades, &

ANO) successfully demonstrated a technique to ultrasonically examine the VSC 24 structural-lid closure wold using time-of flight technology during an NRC inspection at Palisades. This was a major milestone in the process for resumption of fuelloading. Other milestones foi the VSC 24 Owners Group and the Individuallicensees include training and qualification of personnel to perform the examinations, closure of the remaining RAls, and completion of site specific safety evaluations, procedure changes, and training.

NRC remaining milestones include issuance of the inspection report for ultrasonic examination, review and issue documentation to close the Sierra Nuclear Coporation CAL issues related to fuel loading, and site specific inspections to verify implementation of corrective actions and commitments. The target for completion of items and resumption of fuelloading is June / July 1998.

Subject:

VSC-24 UT Inspection Update The inspection team is on a tight schedule this moming and requested not to have a call with us this moming unless absolutely necessary. However, they provided me with the following update The Time-of Flight UT method is a workable method to UT the both casks loaded in the future and those already loaded and in service.

The data scatter is within an acceptable range to be covered by the proposed acceptance criteria.

The inspection will continue in-office for one more week to allow the VSC 24 Owners Group to submit its UT Guideline Document. The document will contain generic information to be included in the loading procedures for each utility and the procedure for UTing previously loaded casks.

The utilities are building a new mock-up which will be used in the future to certify new UT analysts. The mock-up will be controlled such that the location of the flaws will not be known to those individuals being certified.

Overall, things look favorable for the utilities to implement the Time-of Flight UT method.

Please call me with any questions.

Key inspection areas:

Perform a detailed review of the UT methodology employed to examine the structurallid closure weld. This includes actual demonstration of the UT equipment, operation, selection of the proper signals, data acquisition, data analysis, and data interpretation.

The UT technology will be demonstrated, on a full diameter mock up, under simulated field conditions including restrictions on access to the weld volume, elevated temperatures, etc. Evaluate differences between the mock-up and field conditions.

Review tabulated data on UT scans to determine error band on UT method. Data '

includes detection, sizing, type of flaw, location and orientation. Has the VSCOG determined an error band? If so evaluate the adequacy of the error band and the method for detemining it.

Review UT examination procedures. Verify that there are adequate controls described in the procedures t; ensure that personnel are qualified (to take data and/or interpret data), ,

the essential variables are controlled, and that the procedure is sufficiently detailed to  !

produce reliable and repeatable results. An examination strategy with a logic tree format 1 is expected. Evaluate the various branches of the logic tree.

Evaluate UT issues P. Scan lasue 1 UT.'near field" effects. What measures will be taken to address i l UT examination in the near field regime to assure reliable and repeatable I examination results?

P-Scan issue 2 - Transducer size. For flaw sizing, it is generally better to use transducers that produce the smallest practicable sound beam cross section at the

flaw location. The transducer described by the VSCOG produces a sound beam cross sectxmal area much larger than most of the flaws that are being sized. What measures is the VSCOG taking to ensure accurate flaw sizing with the transducer proposed for this UT examination technique? May provide a test block for

. examination by VSCOG. l l
