Questions Re: Review of LaSalle 10 CFR 50.71(e) - April 12, 2012 UFSAR Update Rev 19 Ms. Simpson, Exelon Generation Company, LLC (EGC) submitted Updated Final Safety Analysis Report (UFSAR) revisions pursuant to 10 CFR 50.71(e) for LaSalle County Station Units 1 and 2, to the U.S. Nuclear Regulatory Commission by letter dated April 12, 2012. In review of the UFSAR updates, below are questions related to recently approved licensee amendment requests:

1. LAR 199/186 authorized the installation of NETCO inserts for LaSalle Unit 2 Spent Fuel Pool.

FSAR Section 9.1.2.2.3 reflects that these changes will occur over an extended period of time.

In response to the Boraflex degradation, neutron-absorbing inserts will be placed in the fuel racks of the Unit 2 spent fuel pool. The placement of these inserts will be part of an installation campaign that is to occur over an extended period of time.

By letter dated January 6, 2012, EGC informed NRC that the NETCO insert campaign was completed on December 29, 2011. Please clarify the effective date of the UFSAR revision or explain these differences.

2. LAR 202/189 authorized LaSalle Station to allow receipt of low-level radioactive waste. Please explain whether changes were needed to the UFSAR and the Fire Protection Report as a result of the approval.

3. LAR 204/191 authorized Revised BWR RCS Leakage Detection Instrumentation Requirements.

Please explain whether changes were needed to the UFSAR to clarify system descriptions or facility operations as a result of the approval.

4. Section 9.2.1.1.1 was revised to change the emergency makeup to the spent fuel pool from 50 gpm to 300 gpm. Discuss if a 50.59 screening was performed and whether analyses or engineering evaluation were revised to support this change.

5. Attachment A of EGC letter dated April 12, 2012, states that multiple sections were revised for the Alternative Source Term LAR (Amd Nos. 197/184) and MUR Power Uprate LAR (Amd Nos.

198/185). Please provide a list of UFSAR Section changes for each approval.

Please advise whether a call is need to clarify any of the questions above. A response by December 14, 2012, would be appreciated. Please feel free to contact me with questions or clarifications.

Subject:

NRC ID: AMENDMENT 202/189 LICENSING BASIS QUESTION

Description:

Originator: STEPHEN T SHIELDS Supv Contacted: Guy Ford Condition

Description:

License Amendment 202/189 was received in July, 2011, and authorized LaSalle to receive low-level radioactive waste from other Exelon sites for storage in the IRSF. When the Amendment was approved, plans to actually receive waste on-site had been indefinitely put on hold because an alternative waste site had opened.

The Amendment was put on the books after confirming that the affected corporate procedure had been revised, and the URS implementation action item list was complete. The EC was held open pending any site specific implementation requirements should the station begin receiving low-level waste in the future.

In late 2012, the NRC Project Manager (NRR) did a periodic review of the current UFSAR against recently approved License Amendments, and developed a list of questions related to these Amendments. Because the UFSAR books are only updated every two years, it is understood that they lag behind in showing implementation of recent Amendments. The NRC therefore checks to ensure that the required UFSAR change requests have been submitted, and other administrative requirements have been met.

When answering these questions, it was noted that there was no UFSAR change request associated with the IRSF Amendment. This was initially thought to be appropriate, as there were no physical changes to the facility and no discussion in the SER regarding changes to the UFSAR.

However, further review identified that, in the attachments to the original License Amendment Request, UFSAR changes that "might" be required were listed. This list was identified to the cognizant Design Engineer, and on 1/17/2013, an UFSAR Change Request (LUCR-275) was approved and issued to incorporate the needed changes. The NRC Project Manager was provided the LUCR number and a description of the changes.

On 3/5/13, during the bi-weekly Project Manager telcon, he requested assurance that, since the Amendment was not being utilized at the current time, the attributes of the SER were being met, and that any outstanding actions to receive low-level waste were being tracked in the Corrective Action Program. He was informed that these issues would be entered into the CAP.

There were no other issues identified with the responses to the Project http://eamgenco.ceco.com/cap/servlet/ReportFullARServlet 3/7/2013

Full Action Request Report Page 2 of 3 Manager's questions.

Immediate actions taken:

None required.

Recommended Actions:

30 day ACITs should be issued to Reg. Assurance, Design Engineering and Chemistry (RW) to review License Amendment 202/189 and the SER to verify that all implementation needs, e.g., calcs, drawings, UFSAR changes and procedures, to support the Amendment have been completed.

Additionally, a 45 day ACIT should be issued to Chemistry (RW) to determine whether any site procedures/processes will require revision in order to receive low-level radwaste under this Amendment, and to track implementation of these changes to closure.
