1.0 -PURPOSE This attachment describes the method to be used -tojumpercontainment isolation valves CV-1910 and CV-1911 should they become closed during accident conditions (Containment Isolation). -Inorder to sample the Primary Coolant System (PCS),

CV-1910 and CV-1911 must be open.

2.0 REFERENCES

2.1 Palisades Administrative Procedure 9.31, "Temporary Modification Control" 3.0 INITIAL CONDITIONS ANDIOR REQUIREMENTS 3.1 CV-1 910 and CV-1911 are the containment isolation valves on the PCS chemistry

,sample lines. In the event of a containment isolation signal due to Containment High Pressure (CHP) and/or Containment High Radiation (CHR), CV-1910 and CV-1911 will close.

3.2 To obtain a sample of the PCS under accident conditions using the NSSS panel, it will be necessary to bypass the CHP and/or CHR relay contacts to open these valves.-

4.0 PROCEDURE 4.1 I&C shall verify availability of instrument air before starting Jumpering. This Jumpering can only be performed if instrument air is available..

4.2 1I&C or Electrical Maintenance may obtain jumper set and #10 link nuts from Emergency Maintenance Kit 9 in the Operations Support Center (OSC).

4.3 Request Operations to place HS-1910 and HS-1911 in the open position (CV-1910 and CV-1 911 should remain shut.) Advise Operations that while jumpers are being placed, they will lose valve indications. Valve indications will-be restored after jumpers are in place.

Proc No El-7.0 Attachment 1 JUMFERING CV-19'10 AND CV-1911 Revision 8 FOR PCS- SAMPLE OR SAMPLE LINE FLUSH Page 2 of 3 4.4 Inside C-13 Panel NOTE: Circuits involved labeled P1 are 125 VDC positive supply to valve position indication.

a. Locate 13TV4-28 (P1) scheme S-21 (M201, Sheet 40) and open link.
b. Attach appropriate end of jumper to P1 side to link using #10 nut and link wrench.
c. Locate 13TV6C-19 (91) scheme S-21 (M201, Sheet 113), string jumper so that it is out of the way so as not to be pulled apart, and attach other end of jumper using #10 nut and link wrench.
d. Close link at 131V4-28 (P1) scheme S-21 (opened in a). Verify position indication restored and CV-1910 still closed.
e. Locate 13TV1I1-112 (P1) scheme S-22 (M201, Sheet 35) and open link.
f. Attach appropriate end of jumper to P1 side of link using #10 nut and link wrench.
g. Locate 13TV8C-24 (91) scheme S-22 (M201, Sheet 113), string jumper along floor under grating so it is out of the way and attach other end of the jumper using #10 nut and link wrench.
h. Close link at 13TV11-112 (P1) scheme S-22 (opened in e). Verify position indication restored and CV-1911 still closed.

4.5 Inform Operations that jumpering operation is complete and to place HS-1910 and HS-1911 in the closed position. Returning either hand switch back to the open position will now cause valves to open.

Proc No EI-7.0 Attachment 1 JUMPERING CV-1910 AND CV-1911 Revision 8 FOR PCS SAMPLE OR SAMPLE LINE FLUSH Page 3 of 3 WARNING Once sampling valves are open, a potential exists for High Radiation Fields to be created at the NSSS Panel.

4.6 Request Operations to caution tag HS-1910 and HS-1911 indicating that CHP and CHR relay contacts are jumpered out for CV-1910 and CV-1911.

4.6.1 If the valves remain jumpered open for longer than one shift, then 'Caution tags shall be required. ""

4.7 Removal of Jumpers 4.7.1 I&C or Electrical Maintenance obtain permission from Shift Supervisor to remove jumpers on CV-1910 and CV-1911.

4.7.2 Inside C-13 Panel S NOTE: Circuits involved labeled P1 are 125 VDC positive supply to valve position indication.

a. Locate 13TV, 1-112 (P1) scheme S-22 and open link.
b. Remove appropriate end of jumper using a link wrench.
c. Locate 13TV8C-24 (91) scheme S-22 (M201, Sheet 113) and remove jumper using a link wrench.
d. Locate 13TVI1-112 (P1) scheme S-22 (M201, Sheet 35) and close link.
e. Locate 13TV4-28 (P1) scheme S-21 and open link.
f. Remove appropriate end of jumper using a link wrench.
g. Locate 13TV6C-19 (91) scheme S-21 (M201, Sheet 113) and remove appropriate end of jumper using a link wrench.
h. Locate 13TV4-28 (P1) scheme S-21 (M201, Sheet 40) and close link.
