Palisades Nuclear Plant Conmnitedto Nudea Operated by Nudear Management Company, LLC October 18, 2005 Mr. Robert Schaaf Sr. Project Manager Office of Nuclear Reactor Regulation U.S. Nuclear Regulatory Commission Mail Stop 0-11 F1 Washington, DC 20555 Palisades Nuclear Plant. Response to Suoplemental Questions Concerninn Radioactive Solid Waste Management

Dear Mr. Schaaf:

Enclosed, please find the supplemental information regarding Palisades Nuclear Generating Plant radioactive solid waste management. This information is in response to your supplemental questions in a September 9, 2005 e-mail and subsequent September 12, 2005 conference call. Enclosure 1 and Table 1 provides responses and information to address your inquiries.

Please contact me at 763-295-1309 should you need further clarification.

Sincerely, James Holthaus Environmental Project Manager Nuclear Management Company, LLC Palisades Nuclear Plant

Enclosure I NRC Question la:

1.Attachment 4 of the Annual Radioactive Effluent Release and Waste Disposal Reports (RERWDRs) summarizes all solid radwaste classification, sources, volume shipped, and curie and nuclide content.

a. Please clarify whether this table indicates waste shipped from a third party processing center to a disposal facility or shipped from the Palisades site.

NMC Response to NRC Question la:

The tables contained in Attachment 4 of the RERWDRs for 2000-2004 summarize waste shipped from the Palisades site for treatment or processing. These totals may Include waste sent out for volume reduction; thereby the final waste volume will be lower and may not be realized until following years.

NRC Question Ib:

lb. Provide the volumes listed in Attachment 4 of the RERWDRs are for waste shipped from a third party to a disposal facility, what were the volumes shipped from Palisades in 2000, 2001, 2002, 2003 and 2004? Provide tables similar to those given in Attachment 4 of the RERWDs for the waste shipped from the site in each year.

NMC Response to NRC question Ib:

Attachment 4 of the RERWDRs summarizes waste shipped from the Palisades site.

Table 1 (see attached) identifies the number of shipments of solid waste from the Palisades site, waste class (AS, AU, B. C), location of shipments, total volumes shipped, total curie counts and principal radionuclide compositions for the years 2000, 2001, 2002, 2003 and 2004.

NRC Question 2:

2. How many waste shipments were made from the Palisades site in 2000, 2001, 2002, 2003 and 2004 and where were the shipments sent?

NMC Response to NRC Question 2:

During the period 2000-2004, Palisades made an average of 16 shipments of LLW per year. Table 1(see attached) provides the number of waste shipments made per year from the Palisades site and locations of where the shipments were sent.

Page 1

NRC Question 4: (No Question 3 was provided)

4. What were the quantities (in terms of volume and curie content) of LLW by class (A, B, and C)and mixed LLW generated during 2000, 2001, 2002, 2003, and 2004? What were the inventories stored on site at the end of each year? Where were they stored?

NIMC Response to NRC Question 4:

The quantities of LLW generated in the years 2000-2004 are as follows (after volume reduction):

Year Amount Generated Year-end Estimate Storage Location

_ Stored On-Site2 2000 2834 f 3 total 7106 ft3 East Radwaste Storage Building 2001 3185 ft total 3357 ftP East Radwaste Storage Building 2002w Class A: 1784.7 f3 2860 3 East Radwaste Storage Class B: 145.8 ft3 Building 1930.5 ft3 2003, Class A: 1214.0 ft3 3230.2 ft3 East Radwaste Storage Class C: 180.1 ft3 Building

_________1394.1 f Bilin 2004, Class A: 1400 ft3 ft _4234 East Radwaste Storage Class B: 100ft3 Building

___1500 f 1From Michigan Department of Environmental Quality Annual Low-Level Radioactive Waste Management Surveys.

2 Year-end estimates include 1900 f 3 of containment building concrete material (D-block) removed during steam generator replacement, currently stored adjacent to the Steam Generator Storage Building. This number was not accounted for in Palisades' Annual Low-Level Radioactive Waste Management Surveys to the Michigan Department of Environmental Quality, 2000-2004. The numbers provided here serve as an update to Question 14 A in Palisades' Annual Low-Level Radioactive Waste Management Surveys to the Michigan Department of Environmental Quality, 2000-2004.

Curie content of LLW generated is usually calculated during shipping; therefore, there is currently no estimate of the curie content of waste generated for each year.

Yearly volume estimates of LLW generated do not include 20,000 f 3 designated for disposal of old steam generators, currently stored on-site in the Steam Generator Storage Building. Palisades' old steam generators (2) are designated as decommissioning disposal items.

No mixed waste was stored on the Palisades site from 2000-20q4, nor ES any stored at present. However, Palisades is permitted per the site Treatent Storagb and Disposal (TSD) permit to store up to two 55-gallon drums of lead waste fron plant operations (i.e.

lead paint removal). The Low Level Mixed Waste Unit is located in the East Radwaste Storage Building, inside the Palisades owner controlled area.
