4OA5 Other Activities (TI 2515/191)
The objective of Temporary Instruction (TI) 2015/191, Inspection of the Implementation
of Mitigation Strategies and Spent Fuel Pool Instrumentation Orders and Emergency
Preparedness Communication/Staffing/Multi-Unit Dose Assessment Plans, is to verify
that licensees have adequately implemented the mitigation strategies as described in
the licensees Final Integrated Plan, which was described in letters dated
January 25, 2016, (ADAMS Accession No. ML 16033A353) and July 20, 2015,
(ADAMS Accession No. ML 15205A342) and the NRCs plant safety evaluation
(ADAMS Accession No. ML 16158A432) and to verify that the licensees installed
reliable water-level measurement instrumentation in their spent fuel pools. The
purpose of this TI is also to verify the licensees have implemented Emergency
Preparedness (EP) enhancements as described in their site-specific submittals and the
NRCs safety assessments, including multi-unit dose assessment capability and
enhancements to ensure that staffing is sufficient and communications can be
maintained during such an event.
The inspection verifies that plans for complying with NRC Orders EA-12-049, Order
Modifying Licenses with Regard to Requirements for Mitigation Strategies for Beyond-
Design-Basis External Events (ADAMS Accession No. ML12054A736) and EA-12-051,
Order Modifying Licenses With Regard to Reliable Spent Fuel Pool Instrumentation
(ADAMS Accession No. ML12054A679) are in place and are being implemented by
the licensee. Additionally, the inspection verifies implementation of staffing and
communications information provided in response to the March 12, 2012, request for
information letter and multiunit dose assessment information provided per COMSECY-
13-0010, Schedule and Plans for Tier 2 Order on Emergency Preparedness for Japan
Lessons Learned, dated March 27, 2013, (ADAMS Accession No. ML12339A262).
The team discussed the plans and strategies with plant staff, reviewed documentation,
and where appropriate, performed plant walk downs to verify that the strategies could be
implemented as stated in the licensees submittals and the NRC staff prepared safety
evaluation. For most strategies, this included verification that the strategy was feasible,
procedures and/or guidance had been developed, training had been provided to plant
staff, and required equipment had been identified and staged. Specific details of the
teams inspection activities are described in the following sections.
1. Mitigation Strategies for Beyond-Design Basis External Events
a. Inspection Scope
The team examined the licensees established guidelines and implementing
procedures for the beyond-design basis mitigation strategies. The team assessed
how the licensee coordinated and documented the interface/transition between
existing off-normal and emergency operating procedures with the newly developed
mitigation strategies. The team selected a number of mitigation strategies and
conducted plant walk downs with licensed operators and responsible plant staff to
assess: the adequacy and completeness of the procedures; familiarity of operators
4
with the procedure objectives and specific guidance; staging and compatibility of
equipment; and the practicality of the operator actions prescribed by the procedures,
consistent with the postulated scenarios. The team verified that a preventive
maintenance program had been established for the Diverse and Flexible Coping
Strategies (FLEX) portable equipment and that periodic equipment inventories were
in place and being conducted. Additionally, the team examined the introductory and
planned periodic/refresher training provided to the Operations and Security staff
most likely to be tasked with implementation of the FLEX mitigation strategies. The
team also reviewed the introductory and planned periodic training provided to the
Emergency Response Organization personnel. Documents reviewed are listed in
the attachment.
b. Assessment
Based on samples selected for review, the inspectors verified that the licensee
satisfactorily implemented appropriate elements of the FLEX strategy as described in
the plant specific submittals and the associated safety evaluation and determined
that the licensee was generally in compliance with NRC Order EA-12-049. The
inspectors verified that the licensee satisfactorily:
FLEX strategies for postulated external events.
- integrated the FSGs into existing plant procedures such that entry into and
departure from the FSGs were clear when using existing plant procedures.
- protected FLEX equipment from site-specific hazards.
- developed and implemented adequate testing and maintenance of FLEX
equipment to ensure its availability and capability.
- trained the staff to assure personnel proficiency in the mitigation of beyond-
design- basis events.
- developed means to ensure that the necessary off-site FLEX equipment
would be available from off-site locations.
The inspectors verified that noncompliances with the current licensing
requirements, and other issues identified during the inspection, were entered into
the licensees corrective action program.
c. Findings
No findings identified.
2. Spent Fuel Pool Instrumentation
a. Inspection Scope
The team examined the licensees newly installed spent fuel pool instrumentation.
Specifically, the inspectors verified the sensors were installed as described in the
plant-specific submittals and the associated safety evaluation and that the cabling
for the power supplies and the indications for each channel were physically and
electrically separated. Additionally, environmental conditions and accessibility of
the instruments were evaluated. Documents reviewed are listed in the attachment.
5
b. Assessment
Based on samples selected for review, the inspectors determined that the licensee
satisfactorily installed and established control of the spent fuel pool (SFP)
instrumentation as described in the plant specific submittals and the associated safety
evaluation and determined that the licensee is generally in compliance with NRC Order
EA-12-051. The inspectors verified that the licensee satisfactorily:
- installed the SFP instrumentation sensors, cabling and power supplies to provide
physical and electrical separation as described in the plant specific submittals and
safety evaluation.
- installed the SFP instrumentation display in the location, environmental conditions
and accessibility as described in the plant specific submittals.
- trained their staff to assure personnel proficiency with the maintenance, testing,
and use of the SFP instrumentation.
- developed and issued procedures for maintenance, testing, and use of the reliable
SFP instrumentation.
The inspectors verified that noncompliances with the current licensing requirements,
and other issues identified during the inspection, were entered into the licensees
corrective action program.
c. Findings
No findings were identified.
3. Staffing and Communication Request for Information
a. Inspection Scope
Through discussions with plant staff, review of documentation and plant walkdowns,
the team verified that the licensee had implemented required changes to staffing,
communications equipment and facilities to support a multi-unit extended loss of offsite
power scenario as described in the licensees staffing assessment and the NRC safety
assessment. The team also verified that the licensee had implemented dose
assessment (including releases from spent fuel pools) capability using the licensees
site-specific dose assessment software and approach as described in the licensees
multi-unit dose assessment submittal. Documents reviewed are listed in the
attachment.
b. Assessment
The inspectors reviewed information provided in the licensees multi-unit dose
submittal and in response to the NRCS March 12, 2012, request for information letter
and verified that the licensee satisfactorily implemented enhancements pertaining to
Near-Term Task Force Recommendation 9.3 response to a large scale natural
emergency event that resulted in an extended loss of all alternating current power
(ELAP) to the site and impedes access to the site. The inspectors verified the
following:
- Licensee satisfactorily implemented required staffing change(s) to support an
ELAP scenario.
- EP communications equipment and facilities were sufficient for dealing with an
ELAP scenario.
6
- Implemented dose assessment capabilities (including releases from spent fuel
pools) using the licensees site-specific dose assessment software and approach.
The inspectors verified that noncompliances with the current licensing requirements,
and other issues identified during the inspection, were entered into the licensee's
corrective action program.
c. Findings
No findings identified.
