1 LaSalle Environmental Audit Response to Request for Additional Information Index #:

018 RAI #: LU-02 Category: Land Use and Visual Resources Statement of Question:

The NRCs supplemental environmental impact statement (SEIS) for LSCS license renewal will include a description of fuel at the LSCS site that mirrors Section 3.1.6.1 in the NRCs 2013 GEIS (ML13107A023). To facilitate the staffs preparation of this section, provide the following information:

a. How much nuclear fuel does each LSCS unit contain in pounds or metric tons? The approximate or average weight is sufficient.

b. On average, what percentage of reactor fuel does Exelon replace during each outage?

c. Describe the use and storage capacity of all onsite fuel storage tanks, including diesel, gasoline, and natural gas.

d. How does LSCS power its heating, ventilating, and air conditioning systems?

e. Does LSCS have an onsite waste oil incinerator(s)? If so, please describe the incinerator(s).

Response

a. Each LSCS unit contains approximately 140.0 metric tons uranium (MTU)

b. At each refueling outage, approximately 36 percent of the reactor fuel is replaced in the refueled unit.

c. A description of the use and storage capacity for onsite fuel storage tanks is provided in the table below. [Source: Exelon Generation LaSalle Generating Station Spill Prevention Control and Countermeasures Plan, Rev. 19,April 2015.]

d. In general, LSCS heating, ventilating, and air conditioning systems that are classified as engineered safety features are powered from on-site redundant essential power sources and remain operable during loss of offsite power. Non-safety related heating, ventilating and air conditioning systems in the power block are powered from an onsite power distribution system and would shut down on loss of offsite electric power. Non-safety related heating, ventilating and air conditioning systems in outlying structures are powered from an offsite power distribution system and would shut down on loss of offsite electric power.

e. LSCS has no onsite waste oil incinerator.
