Page 3 of 10 Chapter 1: Introduction and Summary 1.1 Facility Status On July 1,1998 the University of Illinois Nuclear Reactor Laboratory filed for permanent cessation of operations with the U. S. Nuclear Regulatory Commission (NRC) effective at midnight, August 9,1998. On October 5,1998 technical specifications in support of SAFSTOR for the UlUC Nuclear Reactor Laboratory were submitted for review and approval by the NRC.

The facility is currently in the process of preparing for SAFSTOR (details in Chapter 2) and expects to have all preparations complete by January 1,1999.

1.2 Why SAFSTOR

)

Title 10 Code of Federal Regulations part 50.82 (b) (4) (i) states that the proposed decommissioning plan for a non-power reactor must include "7he choice of the alternativefor decommissioning with a description of activities involved. An alternative is acceptable afit providesfor completion ofdecommissioning without sigmfcant delay.

Consideration will be given to an alternative which providesfor delayed completion of decommissioning only when necessary to protect the public health and safety. Factors to be considered in evaluating an alternative which providesfor delayed completion of decommissioning include unavailability of waste disposal capacity and other site-specipe factors afecting the licensee's capability to carry out decommissioning, including the presence ofother nuclearfacilities at the site. " The University of Illinois is placing the facility in a SAFSTOR status based on an estimated shipping date for the TRIGA fuel of 2010 at the earliest (see attached letter from INEEL Spent Fuel Program). The University of Illinois Nuclear Reactor Laboratory is a stand alone facility and cannot commence decommissioning until the fuel is shipped offsite. This situation forces the facility into a SAFSTOR decommissioning option.

! 2.1 Fuel Movement and Storage in order to better facilitate future fuel inspections with minimal fuel movement the fuel

! will be moved to the Bulk Shielding Facility. This action will minimize the potential for damage to a fuel element since this is greatest when an element is being moved. l This will also reduce the amount of time and effort required to inspect the fuel by l placing the elements in racks that allow for visual inspection without having to move the fuel element. New fuel storage racks for the Bulk Shielding Facility (BSF) have been I manufactured based on the approved Safety Analysis P port design. These racks were ,

then installed in the BSF through a 50.59 approved by the Nuclear Reactor Committee l l (see Figures 1 and 2):.

Figure 2 All fuel elements will be visually verified for their serial number and measured for length and bend prior to being placed in long term storage in the BSF.

2.2 Monitoring Systems During the SAFSTOR period the Reactor Administrator and Reactor Health Physicist will have other duties and responsibilities elsewhere on the UIUC campus. In order to better monitor all parameters within the building a computerized monitoring system will be installed :o allow remote monitoring of the reactor building. This system will take inputs from sensors and display them on a computer screen. This computer will be accessible through a network to the reactor staff anywhere on campus through a secure password access In this way the staff may monitor the building critical parameters without necessarilly having to enter the building daily. The facility will be verified by a physical check at least weekly. At a minimum the following parameters will be input to the computer monitoring system:

. TRIGA pool level

. TRIGA pool temperature

. TRIGA pool conductivity

. BSF pool level

. BSF pool temperature

. BSF pool conductivity

. Area Radiation Monitors

• Continous air monitor

. Tunnel sump alarm

. Vault sump alarm

l I

A surveillance schedule has been developed to ensure that the fuel and support systems are monitored appropriately. An example of the schedule can be seen in Figr.rc 3. An

! example of the weekly and quarterly surveillance sheets may be seen in Figures 4 and 5

! respectively. These schedules are examples and subject to change.

2.4 Facility Staffing l

l The University of Illinois has made a commitment to maintain a minimum of two individuals on approximately a 25% time basis for the facility. This commitment is specified in Technical Specification 6.1.2 to be the R.eactor Administrator and the  !

Reactor Health Physicist. Qualification requirements for these individuals are also '

Chapter 3: Funding for SAFSTOR and Final Decomnissioning i

! 3.1 SAFSTOR funding l

In addition to the commitment for staffing previously discussed, the College of l Engineering will provide the necessary funds for maintenance of the support systems in the Nuclear Reactor Laboratory during the SAFSTOR period. These expenditures are estimated to be a maximum of $23,000 per year not including salaries.

3.2 Decommissioning Funding and Update In early 1998 the University of Illinois contracted to GTS Duratek Radiological I Engineering and Field Services to perform a decommissioning cost estimate. The current cost estimate to fully decommission the UlUC Nuclear Reactor Laboratory is l $4,378,380 in 1998 dollars. This estimate will be updated on a biennial basis for intemal planning purposes. At such time that a fuel shipment date is expected a new decommissioning cost estimate will be contracted as part of a full decommissionir.g plan.

At such time that the fuel is shipped offsite and final decommissioning is begun the necessary funds will be appropriated from the State of Illinois to complete the task.

SUBJECT:

Receipt of University of Illinois Spent Nuclear Fuel at the INEEL (OPE-SFP-98-254)

REFERENCE:

1) Richard L. Holm letter to Peter J. Dirkmaat dated July 13,1998.

2) October 17,1995 DOE / Navy / State of Idaho Consent Order / Settlement Agreernent on Spent Nuclear Fuel and Nuclear Waste.

3) Telephone conversation between E. D. Houck, LMITCO, and Mark Kazsor, University of Illinois, on June 19,1997.

Dear Dr. Holm:

This letter responds to your request (Reference 1) Ir. quiring when the Idaho National Engineering and Environmental Laboratory (INEEL) could receive spent nuclear fuel (SNF) from the University of Illinois (Ul) reactor in accordance with the Idaho Settlement Agreement l (Reference 2), the INEEL cannot receive domestic SNF before January 1,2001. In

implementing this constraint, a tentative receipt schedule for domestic SNF receipts has been developed. The schedule currently identifies receipt of the Ul SNF in 2020 and is based on the UIinput last year (Reference 3).

With the decision to close down the reactor in 1998, we recognize your need to have the shipping date moved up if possible. For your planning purposes, the INEEL could probably support any post 2009 receipt date given sufficient notification and funding. Receipt of the Ul SNF from 2001 through 2009 is currently precluded due to high priority SNF receipts already l

scheduled and limitations on the number of receipts within the State of Idaho as established by the Settlement Agreement.
