PLUG WELDING (continued)

NOTE

Weld should have uniform runout of weld flash and no evidence of

cracking in weld runout. Plug should be visually perpendicular

to the reservoir.

[30]

Visually inspect weld for acceptability.

IF the weld appears acceptable,

[a]

THEN mark "YES" in the "Visual Inspection Acceptable"

column of the Check Sheet/Data Sheet

[b]

IF the weld appears unacceptable,

THEN mark "NO" in the "Visual Inspection Acceptable"

column of the Check Sheet/Data Sheet

[31]

IF this is the first reservoir of the day,

OR the first reservoir after an electrode change,

OR the first reservoir after a fixture change,

THEN contact Health Physicist to check for off-gassing from plug.

Health Physicist:

[a]

Verify the off-gassing rate from the reservoir plug is less than

1.0x10-5 microcuries per cc of air.

[b]

IF the Health Physicist identifies that a reservoir exceeds the

off-gassing rate limit,

THEN STOP this procedure,

AND Contact supervisor immediately.
