The amendment is effective as of its date of issuance.
The amendment modifies the ANO-1 TSs to require the ANO-1 purge valves be closed whenever the reactor coolant system temperature is equal to or greater than 200*F. This amendment also updates pages i and it of the TS Table of Contents.
I The application for the snendment complies with the standards and l
requirements of the Atomic Energy Act of 1954, as amenced (the Act),
and the Commission's rules and regulations.

ENCLOSURE i RESTATEMENT OF STAFF POSITION 1.
Purging / venting should be minimized during reactor operation because the plant is inherently safer with closed vent valves (centainment) than with cpen lines which require valve action to provide ccntainment.
(Sericus censideration is being given to ultimately requiring that future piants be designed such that purging / venting is net required during operatien).
2.
Scme purging / venting en current plants will be permitted ;rovided that:
a) purging is needed and justified for safety pur;oses, and b) valves are judged by the staff to be 50:5 cperable and reliable, and c) the estimated accunt of radicactivity released during the time required to close the valve (s) follcuir.g a LOCA either 1.
does not cause the total dose to exceed the 10 CFR Part 100 Guidelines; then a goal should be established which represents a limi: en the annual hcurs of purging ex;ected througn each particular valve, or ti. causes the tctal dose te exceed the guideline valves; then curging/ venting shall be limited to 90 hcurs/ year.
3.
Furging/ venting should not be cermitted when valves are being used that are known to be not c;erable er reliable under transient or accident ccnditions.
