NO.____NSTX-CALC-11-08 DATE___12/12/00_____ ORIGINATOR___C Neumeyer________CHECKER____R. Hatcher___Rev.___0__ PURPOSE: This calculation updates the NSTX plasma disruption calculation from that originally reported in NSTX-CALC-11-01, SPARK Plasma Disruption Simulation which consisted of an axisymmetric, midplane symmetric SPARK run, and an LRSIM run as a cross check. The update described herein accounts for two changes since the earlier work, namely 1) there are no jumpers between the passive plates, and 2) the level of current is increased to 1.5MA. REFERENCES: 1) NSTX-CALC-11-01 2) 13-001212-CLN-01, Minutes of Meeting on Extension of Ip Range to 1.5MA 3) 72-990816-JB-01, Axisymmetric Equivalent Model of NSTX See NSTX-CALC-11-01 for information on LRSIM I/O formats. ASSUMPTIONS: Midplane symmetric disruption 1.5MA/9mS; Per ref. 3, toroidal gap resistance between each primary passive plate pair is 300&! and between each secondary passive plate pair is 400&!; 3) Plasma modeled by two cylindrical conductors at R=0.8m, Z=+/-0.6m, a=0.6m; PF3, and PF5 coils shorted, others open. CALCULATION: See attachments. CONCLUSION: Design basis conditions are established. Compared to prior work (with jumpers between passive plates), current in passive plates is much lower, and current in vacuum vessel is much higher.   8[dz|v CJOJQJ >*OJQJ >*OJQJOJQJ 23Z[@A{|} $0  $  $0 $$ 23Z[@A{|}" t v      '" t v $ & F0 $ & F0  $0 $P/ =!"#$% |HH(EG(HH(d'` [0@0NormalCJOJQJmH <A@<Default Paragraph Font  &     3B%%&BLCharles Neumeyer3Macintosh HD:Desktop Folder:Calc 11-2-0 Cover SheetCharles Neumeyer3Macintosh HD:Desktop Folder:Calc 11-8-0 Cover SheetCharles Neumeyer3Macintosh HD:Desktop Folder:Calc 11-8-0 Cover SheetCharles Neumeyer3Macintosh HD:Desktop Folder:Calc 11-8-0 Cover SheetCharles Neumeyer3Macintosh HD:Desktop Folder:Calc 11-8-0 Cover SheetCharles Neumeyer<Macintosh HD:Temporary Items:AutoRecovery save of Calc 11-8-Charles Neumeyer3Macintosh HD:Desktop Folder:Calc 11-8-0 Cover Sheet  hho()hho()@l@,(@@GTimes New Roman5Symbol3 Arial3Times7 Chicago9New York"A cLF1jLfcLF. !+2dCalc 11-2-0 Cover SheetCharles NeumeyerCharles Neumeyer Oh+'0 $ @ L X dpx'Calc 11-2-0 Cover SheetalcCharles Neumeyer ShharNormal Charles Neumeyer Sh6arMicrosoft Word 8.0h@m@hud@0 ld@Ye  ՜.+,0 hp  'PPPL1- Calc 11-2-0 Cover Sheet Title  !"%Root Entry F1d'1Table WordDocumentSummaryInformation(DocumentSummaryInformation8CompObjX FMicrosoft Word DocumentNB6WWord.Document.8
