ENCLOSURE 1 PROPOSED CHANGE TO TECHNICAL SPECIFICATIONS SALEM GENERATING STATION, UNIT NOS. 1 AND 2 FACILITY OPERATING LICENSES DPR-70 AND DPR-75 DOCKET NOS. 50-272 AND 50-311 Description of Change LCR 87-14 This amendment adds an Action Statement to the Hydrogen Analyzers Technical Specification (TS) 3.6.4.1 for Salem Unit Nos. 1 and 2 addressing the situation where both analyzers are inoperable.
This Action Statement would read as follows:
"With both hydrogen analyzers inoperable, restore at least one analyzer to OPERABLE status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or be in at least HOT STANDBY within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />."
This amendment also modifies Surveillance Requirement 4.6.4.1 by adding requirements for a CHANNEL CHECK once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and a CHANNEL FUNCTIONAL TEST once per 31 days.
The Surveillance Requirement would read as follows:
"Each hydrogen analyzer shall be demonstrated OPERABLE by the performance of a CHANNEL CHECK at least once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />, a CHANNEL FUNCTIONAL TEST at least one per 31 days, and at least once per 92 days on a STAGGERED TEST BASIS by performing a CHANNEL CALIBRATION using sample gases containing:
- a.
Two volume percent hydrogen (low span), balance Nitrogen, and
- b.
Six volume percent hydrogen (high span), balance Nitrogen.
Justification for Change This Action Statement allows operation of the plant for 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> with both hydrogen analyzers inoperable.
It is consistent with the direction given in Generic Letter 83-37, entitled "NUREG-0737 Technical Specifications."
This Generic Letter contained Staff guidance regarding an acceptable containment hydrogen monitor (analyzer) TS.
This guidance reads as follows:
"Two independent containment hydrogen monitors should be operable at all times when the reactor is operating in Power Operation or Startup modes.
LCO for these monitors should include the requirement that with one hydrogen monitor inoperable, the monitor should be restored to operable status within 30 days or the plant should be brought to at least a hot standby condition within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.
If both monitors ar~ inoperable, at least one monitor should be restored to operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or the plant should be brought to at least hot standby condition within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />."
This amendment adds an Action Statement consistent with the above guidance addressing the situation where both hydrogen analyzers are inoperable.
Increased Surveillance Requirements are also being proposed associated with the added Action Statement.
The requested surveillance tests and time intervals are identical to the model hydrogen analyzer TS surveillance requirements provided in GL 83-37.
SIGNIFICANT HAZARDS CONSIDERATION The proposed changes to TS 3/4.6.4.1 do not involve a significant hazards consideration because operation of Salem Unit Nos. 1 and 2 in accordance with these changes would not:
(1) Involve a significant increase in the probability or consequences of an accident previously evaluated.
The hydrogen analyzers provide containment hydrogen concentration indication to control room operators under accident conditions.
The operation or failure of this systems does not lessen any safety systems' ability to perform its design function.
These changes are consistent with the guidance provided in Generic Letter 83-37.
(2) Create the possibility of a new or different kind of accident from any previously analyzed.
The hydrogen analyzers provide indication only.
Their failure to operate cannot create the possibility of a new or different kind of accident.
(3) Involve a significant reduction in a margin of safety.
The hydrogen analyzers, while being required by TSs, do not have an active part in the determination of a margin of safety.
They only provide control room indication of containment hydrogen concentrations during accident conditions.
The added Action Statement and increased Surveillance Requirements are consistent with the guidance given in Generic Letter 83-37.
Furthermore, the increase in the surveillance requirements confirms the operability of the hydrogen analyzers at more frequent intervals.
This provides earlier and more frequent indication to plant operators of the status of the system, thus increasing the probability that it will function as required.
Also, the Commission has provided guidance concerning the application of its standards set forth in 10CFR50.92 for no significant hazards consideration by providing certain examples published in the Federal Register on March 6, 1986, (Federal Register Vol. 51, No. 44).
One of the examples of an amendment which will likely be found to involve no significant hazards consideration is "a change that constitutes an additional limitation, restriction or control not presently included in the technical specification; for example, a more stringent surveillance requirement."
The TS change requested falls into this category in that it increases the control of the hyrdrogen analyzers by adding a requirement to perform a CHANNEL CHECK once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and a CHANNEL FUNCTIONAL TEST once per 31 days.
