Entry  Thursday, November 01, 2018, 13:57, Keith C Ng, Other, Other, Other, nuclear venillation in hot cells not working 
Randomly checked on the nuclear ventilation for the Meson Hall Hotcells and discovered they were not running again (both magnahelic gauges displayed
zero). Attempted to restart the fan manually and the control box seems to not be working. Matt McClean has been contacted and they will look into the problem.

The nuclear ventilation is currently not running in the RHMH hot cells.

 The west side manipulator was removed from the hot cell using the new manipulator removal frame.  The operation went smoothly and required
about one hour with two operators after everything had been prepared.  No contamination was found on the manipulator thru-tube or slave arm.  Only
50cpm were measured on the wrist assembly of the slave end.
Entry  Tuesday, March 27, 2012, 13:14, Isaac Earle, Repair, Target 1, Target, Water removal from T1 monolith downstream.jpgsouth.jpgupstream.jpgM13.jpg
All water was removed from the base of the target hole in the T1 monolith using a suction tube device and wypalls.  Video inspection was performed
and revealed standing water in the unused 4" beam line pipe facing south as well as on the bellows on the M13 beam line.  (Photos attached)
Vacuum group is currently pumping down on the T1 volume to remove the remainder of the water.

 Four water sensors have been installed on top of the T1 monolith.  These water sensors were wired and brought to the area during the 2014
shutdown, but installation was delayed so that the top of the monolith could be painted first.  The sensor labels (attached to the sensor cable) are:
T1, T2, T6, and T8.  The location of each sensor is documented on the diagram below.  Two photos of the top of the monolith are also attached.
Entry  Friday, January 17, 2014, 15:41, Isaac Earle, Standard Operation, Target 1, Target, Water Purged from T1 & T2 Targets 
Water was purged from the T1 and T2 targets using compressed air.  The water is stored in a labeled bucket on the BL1A blocks near the T2 cooling
package.  The bucket is approximately 100µSv/hr on contact and 10µSv/hr at 0.5m.  Isaac's coveralls had 500cpm on them after this job and were dropped off at active
Entry  Wednesday, January 07, 2015, 17:27, Isaac Earle, Repair, Target 2, Water Leak, Water Leaks at T2 Cooling Package 
The T2 cooling package was visually inspected today after blocks were removed.  With the cooling package off the following leaks were observed:
- Collimator A return line ball valve: ~ 2 drops / second
- Collimator B return line ball valve: ~ 1 drop / 3 seconds
Entry  Monday, January 20, 2014, 11:51, Isaac Earle, Repair, Target 2, Water Leak, Water Leak from Meson Hall Mezzanine Near T2 
 A water leak developed this morning from a city water supply line at a hose connection near the T2 expansion tank.  Water was observed to
be dripping off the mezzanine onto the plastic sheet covering the T2 cooling package.  The leak has been stopped and the leaky fitting is being repaired
by Carston Frasden.
Entry  Thursday, May 24, 2012, 18:26, Isaac Earle, Repair, Target 2, Cooling, Water Leak From T2 Cooling Package (Disconnected from Target) 
 Today I noticed a "NOT OK" signal from T2 water expansion tank warning level sensor.  I checked the water level in the tank and
confirmed that the water level in the tank had indeed dropped.  The water package is currently not connected to the target so it is not possible for
this water to enter the beam line.  
Entry  Wednesday, January 22, 2014, 15:41, Isaac Earle, Standard Operation, Target 2, Water Leak, Water Drained From Suck Tube Released 
 After approval from RPG, the water drained from the suck tube, which was stored in a bucket in the RH lab active sink area, was released to the
active drain.  Even after rinsing, the bucket still had a slight field from the base, so it has been labelled and will be kept in the active sink
area.
Entry  Tuesday, March 25, 2014, 18:24, Isaac Earle, Development, Target 2, Water Leak, Water Detecting Sensor Install at T1 & T2 9x
Water detecting strips were installed around the T1 and T2 areas today with Doug Preddy and contractors from SMT Research.  Four sensors were installed
at various locations on each cooling package.  Four sensors were installed on the top surface of the T2 monolith.  In addition, four sensors
were routed for future installation at the T1 monolith (it is currently covered by blocks and requires cleaning and painting before sensor installation).

Six 5 gallon pails were transferred this morning from a temporary storage bunker in the Warm Cell to the Rad Waste Pit for long term storage.  The
pails contain various BL1A active waste from the East Hot Cell including dozens of irradiated beryllium and graphite targets.  The field from the
pails ranged from 0.1 to 9mSv/hr at 0.5m.  The work was performed according to the clean-out procedure (Document-142965). 
Entry  Thursday, August 27, 2015, 15:47, Isaac Earle, Repair, Other, Water Leak, Warm Cell Water Window Seal Replacement Update 
Since the previous E-Log the following tasks have been completed:
- Panel spacer rods installed at 4 locations in each tank (two top, two bottom at approximately 1/3 and 2/3 the way across)
- Spacer rods expanded only slightly to begin compressing the rubber window spacers while still leaving at least a 8mm gap between window and frame

Entry  Monday, September 28, 2015, 11:33, Isaac Earle, Repair, Other, Water Leak, Warm Cell Water Window Repair Complete 
The warm cell water window tanks were filled on September 17 after 2 weeks of curing time.  A water leak was found coming from the seals of a plastic
pipe joining the two tanks near the top.  This was repaired using rubber gaskets and quick cure caulking.  The tank was refilled on September
18 and no longer leaked from that location.  The sand filter was backflushed with the water exhausted to the grass area outside the hot cell lab until
