13. 13 PVNGS installed a fire protective material Thermo-Lag 330-1 on electrical raceway systems from 1983 - 1987
NRC Generic Letter 92.08 - Thermo-Lag fire endurance, ampacity, seismic integrity, quality and Quality Assurance Program vendor data suspect
PVNGS ELECTRICAL RACEWAY PROJECT
14. 14 PVNGS committed to determine installed as-built weight of Thermo-Lag. Average weight per square foot, 1-hr fire barrier, TPE (thickness 0.80"; density 71 lbs/ft3) = 4.73 lbs/ft2
Resultant over-weight conduit following incorporation of Thermo-lag data into raceway weight tracking database
Unit-1 = 787 overweight conduit runs
Unit-2 = 578 overweight conduit runs
Unit-3 = 449 overweight conduit runs PVNGS ELECTRICAL RACEWAY PROJECT

20. 20 GTS UNISTRUT CAPABILITIES GTSTRUDL UNISTRUT Design
Specifically designed for nine (9) different UNISTRUT cross-sections
Code checked based on AISI "Specification for Design of Cold- Formed Steel Structural Members" adopted August 19, 1986 w/ December 11, 1989 Addendum
Design Code name = AISI89
Table name = UNISTRUT
Profile names = P1000, P1001, P1001A, P1001B, P1001C, P10013, P1001A3, P1001C41, and P1004A ref. UNISTRUT Metal Framing, General Engineering Catalog No. 12
21. 21 AISI89 Code Parameters are grouped into 3 general categories:
System Parameters
System Parameters monitor SELECT and CHECK Command results (Section 7.2 of Volume 2A)
Control Parameters
Control Parameters decide provisions to be checked; specify comparison tolerances - seldom used except CODETOL
Code Parameters
Code Parameters specify information / coefficients referenced in the code GTS UNISTRUT CAPABILITIES

GTS UNISTRUT CAPABILITIES
23. 23 GTS UNISTRUT CAPABILITIES CODE CHECK command executes code provision checks and
Returns top 2 highest ACTUAL/LIMITING values
24. 24 GTS UNISTRUT CAPABILITIES Troubleshoot “failed” members using the SUMMARIZE CODE CHECK command to print computed code provision values
25. 25 UNISTRUT Connection Analysis and Design Feature
MEMBER RELEASE command of Section 2.1.8.2 of Volume 1 modified to include a TYPE option for elastic connection specifications developed for APS connection types GTS UNISTRUT CAPABILITIES
26. 26 Elastic Connection option in the MEMBER RELEASE command provides an elastic spring restraint between one or both ends of the member and the incident joints
‘elastic.con’ file installed in GTSTRUDL installation directory
ASCII file contains elastic connection types, connection force/moment capacities, Translational / rotational elastic connections at the ends of the members
Free format data to be specified
Number of elastic connection types stored in file
Connection Type ID; Capacities = FX, FY, FZ, MX, MY, and MZ; followed by Spring Values = KFX, KFY, KFZ, KMX, KMY, and KMZ
Directions X, Y, and Z = local coordinate system of the member
Capacities/elastic connection springs in GTSTRUDL default units (inches, pounds, and radians)
Fixed DOF= 999999 value GTS UNISTRUT CAPABILITIES

29. 29 GTS UNISTRUT Feature Benefits
Code Checking Capabilities greatly expedited post-processingresults - PVNGS Conduit Systems were determined to meet Seismic Category 1 requirements
UNISTRUT code check is available to all users; Documentation available upon request
Code Check based on AISI 1986 Edition (w/ 1989 Addendum) Load Capacity Determination procedures - cold formed steel equations are force-based; not stress-based equations (similar to AISC LRFD concept)
GTS UNISTRUT CAPABILITIES
30. 30 Provide REDRAW SOLID capabilities – Beta angles for non-symmetrical shapes are difficult to verify without REDRAW SOLID
