| Title | 24-Hr Incident Report - Safety System Actuation |
| Event Description | At 0830 hours0.00961 days <br />0.231 hours <br />0.00137 weeks <br />3.15815e-4 months <br />, Autoclave #5 in the X-343 Facility experienced a Steam Shutdown due to high condensate level alarm (B) actuating. The autoclave was in TSR applicable Mode IV 'Feeding, Transfer or Sampling' when the actuation occurred. This is considered a valid actuation of a 'Q' Safety System. The autoclave was placed in Mode VII 'Shutdown' and declared inoperable by the Plant Shift Superintendent (PSS). An investigation is underway to determine the cause of the actuation. No release of radioactive material occurred as a result of the incident. This is being reported in accordance with UE-RA-RE1030 Appendix D.J.2. 'Safety Equipment Actuations.'
The licensee notified the NRC Program Manager and will notify the DOE site representative.
Following an investigation into the circumstances surrounding this incident by PORTS Nuclear Regulatory Affairs and Engineering, a recommendation was made to the PSS Office that this event be retracted. The recommendation was based upon the determination that 'Steam Shutdown' occurred as a result of an invalid signal to 'B' condensate level alarm. The follow-up testing of the redundant 'A' condensate level probe and condensate drain system confirmed a high condensate level condition was not present when 'B' condensate level alarm actuated. Per the reporting criteria as stated in PORTS SAR section 6.9, Table 1, criteria J.2, this is not a reportable event due to the 'Q' system actuation being caused by an invalid signal. Based upon the information provided, the PORTS PSS Office is retracting this event. Notified R2DO (Henson) and FSME EO (Morell). |
