Equipment Class representation is defined as 90" plus 2 "for mounting channel. This would be all outlier since itfails to meet the intent of Caveat #1.

Revision 4.4 (7/24/2013)

Outliers

Persons who resolve outliers should have the appropriate qualifications.

• SeIsmic Capability Engineer

• Lead Relay Reviewer

• Systems Engineer

Utility Responsibility

• Resolve using existing procedures

• Identify and lusHly unresolvable outliers

• Explain Implications

Revision 4.4 (7/24/2013)

Typical Methods of Resolving Equipment Outliers

• Modification of equipment

• Replacement

• Obtain more Information

• Vendor qualification reports • Drawings • Reports from other utilities

• Select alternative safe shutdown path

Unit VillA - Outlier Resolution S0103-03IVIIiA (VIOE0) VCWKE'I(V2 PM4 (7/93)

Outliers

Some oCltliers can he resolved as a group by resolving the bounding case. Caveat #1 (requiring bounding by the-equipment class) is not met in these three cases, becau.se the heights of the cabinets plllS the mounting channels exceed 92 inches.

Other methods of resolving outliers:

• In-situ testing

• Shake table testing

• Specific data base review

• Analysis or other engineering evaluations

5

Revision 4.4 (7/24/2013)

Outliers

GIP screening criteriafor relays are conservative.

Specific shake table testing can be conducted.

Example of Outlier Resolution Methods

Method Example

_ Anchorage modification _ Top brace cabinet

_ Replace _ New lead calcium battery replaces lead antimony

_ Analysis _ Battery racks without bracing

_ Data base _ Submersible pumps

_ Testing _ Compact components. new relays

_ Alter shutdown path _ HPCI VS. LPCI

_ Regeneration of spectra _ More realistic demand

Unit VillA - Outlier Resolution S01O:;·():jIVIlIA (VIDEO) VGWKOIKVl PM! ,7·<::"

Outliers

Olltlier resollltion techniques for relays:

• Modify the circuit

• Relocate the relay

• Replace the relay

• Stijfen the relay nW1Ultillx

• Use other jllstijiahle approaches

7

Revision 4.4 (7/24/2013)

Outliers

Top bracing of cabinet increases capacity in two ways:

1) Reduces anchorage load 2) Raises naturalfrequenc.:y

Regenerating in-structure response spectra may demonstrate that the equipment capacity exceeds demand.

Other outlier resolution methods may be used if justified.

The information on this OSVS is, to the best of our knowledge and belief, correct and accurate, and resolution of the outlier issues listed on the previous page will satisfy the requirements for this item of equipment to be verified for seismic adequacy:

Approved by: (For Equipment Classes #0 - '22, all the Seismic Capability Engineers on the Seismic Review Team (SRT) should sign; there should be at least two on the SRT. One Signatory should be a licensed professional engineer. For Relays, the Lead Relay Reviewer should sign.)

Walkdown Approaches--------

Walkdown Approaches

• High Intensity

• Low Intensity

• Combination

\lillO-IS

Comparison of Approaches

Time VWOt4P

High Intensity Evaluation

• Numerous SRTs Needed

• Concentration of Talent Can Improve Judgment

• Performed During a Short Period of TIme (During Outage)

• Coordination is Essential

\IIAD-IS

Section VIII.D - Planning and Conducting Walkdown

Revision 4.4 (7/24/2013)

Low Intensity Evaluation

• One SRT Could Do All Work

• Most of Work Done Over Extended Period of Time (During Plant Operation & Outages)

• Records Collected as Needed

• Less Impact on Plant Activities

VlllOole

Combination Evaluation

• Staff Seismic Engineers Do Bulk of Work

• Seismic Capability Engineer Supervises Work

• Work Done Over An Extended Period of Time

• Senior SRT Performs Thorough Review & Walkdown Over Short Period of Time

Factors Affecting Selection of Walkdown Approach

• Background and Experience of Available Personnel

• Budget

• Outage Schedule
