|
D. Wang reports that recently the overhead crane has been exhibiting a delayed start (approx. 1 min) when operating in local mode. This issue applies
to the main hoist's up/down functionality only and does not seem to apply to other motion axes. T. Kauss briefly investigated but did not find any obvious
cause. |

Scott Adair from Riada sales came to site to complete diagnostics on the ONICON flow meter. He could not determine the problem and believes that
there was a short in the head. He has taken the flow meter for what should be warranty repair. The flow meter is for diagnostics only, the conditioning
station can still operate without it. |

Testing was performed on August 9th on the ISAC nuclear ventilation system to determine if the existing ventilation system can achieve the required cell
depressions for both SHC and NHC under all expected configurations and if a proposed modification to the DDC control system can provide acceptable stability
and response time for the system. The proposed control system observes the lower of the SHC depression or the NHC depression + 10% (to avoid stability |

The North Hot Cell shielding window gaskets have been changed and the window has been filled with new oil. Although there was no noticeable
oil leaks before starting the job, the gaskets had not been changed since initial installation approximately 15 years ago, so they were done now as part
of construction of the new cell. The work took place between January 26 – Feb 8, 2017 following the attached PDF “Full procedure |

A meeting was held on May 4, 2016 to determine the scope of the North Hot Cell project. The following was agreed upon by those in attendance:
The NHC will be a designated target change hot cell. It will be capable of performing all routine target operations (target removal/installation,
leak check, electrical check, video inspection, post irradiation examination, target waste packaging and removal) using the same method currently used |
