01/17/2012 Revised Commitment Description Operation in the recirculation mode of Control Area Ventilation (CAV) is no longer required during deliveries of Ammonium Hydroxide to prevent exceeding the toxicity limits specified in Regulatory Guide 1. 78 Revision 1.
Justification for Change The practice of placing CA V in recirculation mode of ventilation during receipt of Ammonium Hydroxide is no longer required during normal deliveries since implementation of a design change that reduced the ammonium hydroxide delivery volume.
The original installed ammonium hydroxide storage tank held a volume of 3000 gallons. The postulated release of the chemical directly from a 2000 gallon tanker while onsite during delivery was determined to challenge the toxicity limit specified in Regulatory Guide 1.78 Revision 0. Administrative controls were therefore implemented into S1/2.0P-SO.CAV-0001 to instruct the Salem control room to place the ventilation system in the recirculation mode of operation every time a tanker of ammonium hydroxide was delivered to the site.
Design changes 80070384 and 80072671 implemented the use of 350 gallon totes of ammonium hydroxide to lower the risk of spills and personnel
Attachment LR-N13-0088 Page 2 of 3 injury during filling. The new chemical addition system is designed such that one tote serves as the in service inventory while another tote sits on top of the in service tote and is supplied with a quick-disconnect and is used for filling the other. Rupturing one tote would have the potential to allow a release of approximately 700 gallons of ammonia hydroxide. A catastrophic failure and release of 800 gallons of ammonia hydroxide was evaluated to occur at the closest point of the chemical container dike curb to each individual control room ventilation intake in calculation S-5-CAV-NEE-1868 Revision 1.
The analysis concluded that the worst case scenario caused a control room concentration of ammonium hydroxide of 36 ppm. The limit specified in Regulatory Guide 1. 78 Revision 1 is 300 ppm, which is significantly higher than the calculated 36 ppm.

TSI for units 1 and 2 will be issued by 12/92 to limit the time the D vital instrument bus may be inoperable during modes 1-4: The allowed outage time will be no more than 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> and will be addressed in the evaluation for the TS. The TSI will remain in effect until extension of the allowed outage time or deletion of the TSI is justified by further evaluation or the tech specs are changed to include the D inverter Source Document:
