| AGREEMENT STATE REPORT |
| |
| ANCORE (previously SAIC) had requested to delete three nuclides from their |
| CA RML. One of the items ANCORE asked to be deleted were fuel rods |
| containing SNM. A letter for additional information concerning |
| transfer/disposal of the fuel rods went out on May 25, 2000 but received no |
| response. Tom Schell contacted the current RSO, David Mahood. Mr. Mahood |
| stated that the fuel rods were sent to Combustion Engineering before he came |
| to ANCORE. Mr. Mahood further added that his questions to the previous RSO |
| failed to produce any new information or documents concerning the fuel rods. |
| Tom Schell also contacted Brian Horn of the US NRC and the US Nuclear |
| Tracking Database confirms the transfer of the three fuel rods to SAIC in |
| San Diego, a different California license, in September 1989. A review of |
| the Compliance and Licensing Folders SAIC's San Diego License (License |
| Number 2290-37) was done but independent confirmation relating to the |
| receipt of fuel rods containing SNM at SAIC in San Diego were not found. A |
| Note: California regulations only require record keeping for three years, |
| however 10 CFR 150.16 appears to have been violated. Personnel of |
| California Radiologic Health Branch were informed. |

| 10 CFR PART 21 NOTIFICATION FOR DISCREPANT WEIGHT OF SPENT FUEL RACKS |
| |
| Spent fuel tacks removed from Byron Nuclear Power Plant were discovered to |
| have as-found weights ranging from approximately 8,200 to 10,500 lbs more |
| than the weights used in the analyses supporting the original design and |
| licensing of these racks and in the design of the lifting equipment used to |
| lift the racks. The analyses related to seismic loadings, bearing pad |
| design, spent fuel pool liner fatigue, and possibly others used to design |
| and license these racks may no longer be conservative when the additional |
| weight is considered. The actual impact on these analyses has not, to our |
| knowledge, been evaluated. The impact on the design of the lifting |
| equipment is that the design safety factors for the lifting equipment, while |
| still above 1.0, may not meet the minimum safety factors in NUREG-0612 and |
| associated reference documents. |
| |
| Braidwood Nuclear Station has four similarly designed racks provided by the |
| same supplier. |
