RidsNrrDorlLpl3-2 Resource | Dear Mr. Hanson: | ||
Darrell Roberts Richard Skokowski Allan Barker Carole Ariano Linda Linn DRPIII DRSIII Jim Clay Carmen Olteanu | On April 11, 2016, the U. S. Nuclear Regulatory Commission (NRC) will begin a triennial | ||
baseline Component Design Bases Inspection (CDBI) at the LaSalle County Station, Units 1 | |||
and 2. This inspection will be performed in accordance with NRC Baseline Inspection | |||
Procedure 71111.21. | |||
The CDBI focuses on the design, maintenance, and operation of risk-significant components | |||
associated with one or more accident scenario or systems. The components to be reviewed | |||
during this baseline inspection will be identified during the in-office preparation week that occurs | |||
prior to the first onsite inspection week. In addition, operating experience issues, associated | |||
with the component samples, will also be selected for review. The inspection team may request | |||
scenarios to be performed on the simulator. This request would require support from your | |||
simulator staff to validate scenarios, simulator time, and a crew to perform the actions which | |||
would most likely occur during the second onsite week. The team will work closely with your | |||
staff early on during the inspection process to ensure this activity can be accomplished with | |||
minimal impact. | |||
The inspection will include three weeks onsite. The inspection team will consist of six NRC | |||
inspectors, of which five will focus on engineering/maintenance and one on operations. The | |||
current inspection schedule is as follows: | |||
Onsite weeks: April 11 - 15, 2016; | |||
April 25 - 29, 2016; and | |||
May 9 - 13, 2016. | |||
B. Hanson -2- | |||
The team will be preparing for the inspection, mainly during the week of April 4 - 8, 2016, | |||
as discussed in the enclosure. | |||
Experience with previous baseline design inspections of similar depth and length has shown | |||
that this type of inspection is extremely resource intensive, both for the NRC inspectors and the | |||
licensee staff. In order to minimize the inspection impact on the site and to ensure a productive | |||
inspection for both parties, we have enclosed a request for information needed for the | |||
inspection. | |||
It is important that all of these documents are up-to-date and complete in order to minimize the | |||
number of additional documents requested during the preparation and/or the onsite portions of | |||
the inspection. Insofar as possible, this information should be provided electronically to the lead | |||
inspector. The information request has been divided into three groups: | |||
* The first group lists information necessary for our initial inspection scoping activities. | |||
This information should be provided to the lead inspector no later than February 29, | |||
2016. By March 11, 2016, the lead inspector will communicate the initial selected set of | |||
approximately 20 components. | |||
* The second group of documents requested is those items needed to support our in- | |||
office preparation activities. This set of documents, including the calculations associated | |||
with the initial selected components, should be provided to the lead inspector at the | |||
Regional Office no later than March 30, 2016. During the inoffice preparation activities, | |||
the team may identify additional information needed to support the inspection. | |||
* The last group includes the additional information above, as well as plant specific | |||
reference material. This information should be available to the team onsite on April 11, | |||
2016. It is also requested that corrective action documents and/or questions developed | |||
during the inspection be provided to the lead inspector as the documents are generated. | |||
The lead inspector for this inspection is Néstor J. Féliz-Adorno. We understand that our | |||
licensing contact for this inspection is Dwi Murray of your organization. If there are any | |||
questions about the inspection or the material requested in the enclosure, please contact | |||
the lead inspector at (630) 829-9739, or via e-mail at Nestor.Feliz-Adorno@nrc.gov. | |||
This letter does not contain new or amended information collection requirements subject to | |||
the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). Existing information | |||
collection requirements were approved by the Office of Management and Budget, Control | |||
Number 3150-0011. The NRC may not conduct or sponsor, and a person is not required to | |||

SUBJECT: LASALLE COUNTY STATION, UNITS 1 AND 2 - REQUEST FOR INFORMATION
FOR AN NRC TRIENNIAL BASELINE COMPONENT DESIGN BASES
INSPECTION; INSPECTION REPORT 05000373/2016007; 05000374/2016007
Dear Mr. Hanson:
On April 11, 2016, the U. S. Nuclear Regulatory Commission (NRC) will begin a triennial
baseline Component Design Bases Inspection (CDBI) at the LaSalle County Station, Units 1
and 2. This inspection will be performed in accordance with NRC Baseline Inspection
Procedure 71111.21.
The CDBI focuses on the design, maintenance, and operation of risk-significant components
associated with one or more accident scenario or systems. The components to be reviewed
during this baseline inspection will be identified during the in-office preparation week that occurs
prior to the first onsite inspection week. In addition, operating experience issues, associated
with the component samples, will also be selected for review. The inspection team may request
scenarios to be performed on the simulator. This request would require support from your
simulator staff to validate scenarios, simulator time, and a crew to perform the actions which
would most likely occur during the second onsite week. The team will work closely with your
staff early on during the inspection process to ensure this activity can be accomplished with
minimal impact.
The inspection will include three weeks onsite. The inspection team will consist of six NRC
inspectors, of which five will focus on engineering/maintenance and one on operations. The
current inspection schedule is as follows:
Onsite weeks: April 11 - 15, 2016;
April 25 - 29, 2016; and
May 9 - 13, 2016.
B. Hanson -2-
The team will be preparing for the inspection, mainly during the week of April 4 - 8, 2016,
as discussed in the enclosure.
Experience with previous baseline design inspections of similar depth and length has shown
that this type of inspection is extremely resource intensive, both for the NRC inspectors and the
licensee staff. In order to minimize the inspection impact on the site and to ensure a productive
inspection for both parties, we have enclosed a request for information needed for the
inspection.
It is important that all of these documents are up-to-date and complete in order to minimize the
number of additional documents requested during the preparation and/or the onsite portions of
the inspection. Insofar as possible, this information should be provided electronically to the lead
inspector. The information request has been divided into three groups:
- The first group lists information necessary for our initial inspection scoping activities.
This information should be provided to the lead inspector no later than February 29,
2016. By March 11, 2016, the lead inspector will communicate the initial selected set of
approximately 20 components.
- The second group of documents requested is those items needed to support our in-
office preparation activities. This set of documents, including the calculations associated
with the initial selected components, should be provided to the lead inspector at the
Regional Office no later than March 30, 2016. During the inoffice preparation activities,
the team may identify additional information needed to support the inspection.
- The last group includes the additional information above, as well as plant specific
reference material. This information should be available to the team onsite on April 11,
2016. It is also requested that corrective action documents and/or questions developed
during the inspection be provided to the lead inspector as the documents are generated.
The lead inspector for this inspection is Néstor J. Féliz-Adorno. We understand that our
licensing contact for this inspection is Dwi Murray of your organization. If there are any
questions about the inspection or the material requested in the enclosure, please contact
the lead inspector at (630) 829-9739, or via e-mail at Nestor.Feliz-Adorno@nrc.gov.
This letter does not contain new or amended information collection requirements subject to
the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). Existing information
collection requirements were approved by the Office of Management and Budget, Control
Number 3150-0011. The NRC may not conduct or sponsor, and a person is not required to
respond to, a request for information or an information collection requirement unless the
requesting document displays a currently valid Office of Management and Budget Control
Number.
