Patients are expected to be moved back into parts of Wales' only children’s hospital by Thursday.
The Noah's Ark Children's Hospital for Wales was closed because of water damage yesterday due to torrential rain earlier in the week.
Eighteen children in total were moved to other child health areas.
Phil Barry, Directorate Manager for Child Health, said: “All the staff involved have been fantastic. Our priority has been to provide an environment and safe care to all those affected by the incident."
Work to determine the exact cause and to asses the extent of the damage to the higher floors will continue over the next few days.
Patients are expected to be moved back into parts of the Children's Hospital for Wales within the next 36 hours.
Work to determine the cause of flooding yesterday, and to assess the extent of damage to upper floors, where water has been found in the electrical trunking systems and light fittings, will be continuing over the next few days.
All the staff involved have been fantastic. Our priority has been to provide an environment and safe care to all those affected by the incident. Clinical, estates and operational services staff have been working together to begin putting things right and re-establish care in the Children’s Hospital.
We are now hoping to be able to move the first group of patients back into the Children’s Hospital by Thursday which is a testament to the hard work everyone has put in.

Cardiff and Vale University Health Board says services at the hospital have remained in place, and has advised patientsand their families to come to the hospital as normal, unless they are told otherwise.
Dr George Findlay, Cardiff and Vale University Health Board's Clinical Board Director for Children and Women, told ITV News that between six and 12 inches of water had flooded the top two floors of the Children's Hospital for Wales - and some ceiling tiles had come down with the force of the water.
Cardiff and Vale University Health Board said that "torrential rain" yesterday caused water to enter the Children's Hospital for Wales.
The hospital has been "temporarily evacuated" while the extent of water damage is assessed.
It says 18 patients have been safely moved to child health areas in the main University Hospital of Wales building, and are being cared for by staff from the children's hospital.
Our teams were superb in swiftly moving children out of the affected areas and identifying safe and appropriate areas within the main hospital as temporary accommodation.
No-one was injured in the incident and everyone has remained calm, with staff helping patients and their families settle in to their new environments. Our estates team is currently assessing the damage but it is likely the Children’s Hospital will be out of action for the remainder of this week.

Paediatric emergency and elective inpatient services have not been affected.
The cause of the flooding is currently being investigated.
An art exhibition by young patients depicting their experiences of hospital has been described as 'eye-opening' by staff working in the health sector.
Looking at the way the children have expressed themselves through their artwork gives us, as adults and clinicians, a very different perspective on what it’s like to be a young person in hospital.
We hope that this year’s art project has provided our young patients with an opportunity to express themselves through creative work and helped them feel more comfortable at what can be a worrying time in their lives.

Children's Commissioner Keith Towler will today visit Noah's Ark Children's Hospital for Wales to unveil an art exhibition depicting young patients' experiences of hospital.
The youngsters have worked alongside artists from Valley and Vale Community Arts for the project, which is funded by the Arts Council of Wales.
Many patients have long-term conditions which make them frequent visitors to the children's hospital.
Through the project, they turned to paint and pencils to share their their emotions as they went through treatment.
Linda Hughes-Jones, who works for Cardiff and Vale University Health Board and also led the project, said the artwork is 'eye-opening' and has given health workers 'a different perspective' on how it feels to be a young person in hospital.
The artwork will be displayed on the hospital walls, as well as appearing in a short DVD.
Schoolchildren have unveiled the names and designs they have chosen for the new areas of the Children's Hospital for Wales. Building work to extend the current site is underway, and when it's finished, the hospital is expected to treat around a 100,000 young people every year. Esyllt Carr reports.
